Sound lags during music playback - Nexus 7 Q&A, Help & Troubleshooting

Hi guys. I got myself a 32gb, wifi only version of N7. Upgraded it instantly to 4.2.2 . Nothing to complain about in the first 2 days.
After that, I noticed that, when I play music (stream through upnp on local network or play mp3 / flac files on local storage - tested several players, bsplayer, google player, poweramp...), and do some other stuff on the tablet at the same time - surf, or just 'click around', or swipe through my documents - occassionally I experience short sound dropouts, like the I/O-load would be too high or something. Please note this isn't bluetooth thing some people experienced, I use regular phones. It happens sometimes when I do some trivial stuff...noticed it all over the place, while starting an app, surfing, writing something in the Google search window, searching people on FB, opening a browser (empty) tab, even clicking on application button to see the list. It can be really anything, it doesn't happen a lot but it's there.
I googled the problem but couldn't find anyone with similar issues. Read on the other hand a lot about general performance issues of the Nexus 7 after 4.2.2 upgrade, about (visual) lag, so I figured, even though my eye didn't catch that on my device (this is my first experience with 4.x.x so it looked fast and smooth enough to me), I decided to revert to 4.1.2 and see whether there would be any difference. I can't say I could see/hear improvement, maybe a slight one, but I still get to experience occassional chops in my music, which is very annoying, this should be ridiculously easy for a 4-core processor to accomplish. It's unacceptable. I even checked that CPU wasnt overloaded when these chops occured (in fact, it was only around 25%-30% when the chops occured, perhaps the peaks were too short for program to register them - I dunno)...
I also tried everything people suggested here regarding general performance issues, disabling this and that, Currents, factory resets, cleaning cache partition...you name it. Nada.
Anybody experienced similar thing? Don't know if I have faulty unit or if this is bug in software (Samsung Galaxy S3 had a similar thing when it got out, even though the sound pops were of different nature and occured under different circumstances - took several software upgrades until it got fixed)...I'm thinking of returning it and go for iPad mini or something.
Thanks in advance for any feedback.

The results of this have varied but there are some who attest that this works.
Have you disabled auto-sync in Google Currents (Blue Circle Icon)?
If not, try that; this has worked for me.
Open up "Google Currents" Hit the 3 dots on the top right -> Settings -> Scroll down and UNCHECK "Enable background sync"
Remember these results have varied, but it fixed the issue with my tablet. Also I heard there were some issues (although if someone can confirm them further for us--that'd be appreciated!) with the RAM in many Nexus 7s so stressing out the ram and filling up your SDcard to the max will cause it to have stutter issues too.

Hi and thanks for the suggestion,
Disabling the background sync in Google Currents was actually the first thing I did. I believe I tried out everything that was suggested so far on the net regarding the general performance issues. I used Forever Gone app to fill up all space and then delete it, I wiped the cache partition in bootloader mode, I even did a factory reset, and eventually I re-flashed it back to 4.1.2 (it did improve then but the music lag / pops were still not entirely gone). SD-card space-thing cannot be the issue either as I have like 23gigs free.
Now I even noticed that video playback is effected by occasional sound pops. When I play video in full screen, not doing anything else, it still happens. Rarely but it does happen.

Returned it and took money back. Will look for other options soon. This thing was too 'beta' for me.

Sound Drop Outs While Tablet is "Off."

Hi Folks:
Is anyone else having this problem?
New Info as of 16 July. Sound Still Skipping
Unfortunately, I'm still having sound file skips when the tablet is off.
I did some more Google research on this, and I found several instances with regard to phones having sound problems with skipping and popping sounds while playing. Nearly all of those seemed to be related to either headphone issues or the Bluetooth xceiver.
I originally though this problem was specific to Overdrive Media console, but it has also turned up in the Music app. I also installed a couple of other music/sound apps to see if it may be app specific, but all of them had the same consistent behavior of the sound file...pausing at random intervals....and then continuing after a few seconds when the screen...was turned off. The skips DO NOT happen when the screen is on.
Going through Erica Rene's thoughts I went into the Running Applications Manager and turned off several services I wasn't using, including Neo Player, 3d Gallery, Skype, and even Music. I initially thought that worked, but I was wrong. Same behavior.
This morning I did a factory reset. No change in behavior.
Since I just started using the tablet for audio books and podcasts I honestly don't know if this problem was there in 3.0. When I did the factory reset I thought the tablet might go back to 3.0, but I was wrong. I am still on build Acer_A500_4.010.08_COM_GEN2 after the factory reset.
There seems to be nothing wrong with my hardware that I can see. These skips happen with the headphones in or out. The only thing that triggers it is turning off the screen.
Insofar as software is concerned, I've not done anything more except rooting the tablet (which survived the factory reset process, which did surprise me! ). Beyond putting in another ROM - which, unless I can get some specific thoughts that it will fix the problem, given my experience level I'm a bit leery of doing - I can't see how software would fix it now.
Is anyone else seeing this???
Thanks!!!!
=============================
I've searched Google and here on XDA for this and not found anything, so I'm hoping that someone can say something.
When I play a sound file on my A500, and then turn it off, the sound continuing to play is a very iffy thing. This works on my Nexus One phone, so I assumed it would work here. On my phone I start a sound file running (music, podcast, audio from an audio book or Google reader) and then I turn the phone "off" to conserve the battery, of course. The sound continues to play.
When I do the same thing on the A500 it is very rare that the sound continues to play. Sometimes it will stop as soon as I turn the tablet off, sometimes it will continue for several seconds and then stop, sometimes it will continue for several seconds and then pause for a couple of seconds and continue in this loop for the life of the file.
I originally thought that this was a specific issue with the audio books in the Overdrive Media Console program, but I've now encountered it with Google Reader and playing things through either Music or Rockplayer Lite.
Has anyone seen this yourself, or does anyone have any thoughts? Details on the tablet are below:
OS: AndroidOS 3.1
Build: Acer_A500_4.010.08_COM_GEN2
Rooted
Could be some of the apps not playing fair.
Do you have a task killer or any add on management app.they can cause this
Also in settings sounds.there is a check button to control this.
Also do not hit the back button on the apt this will kill it
I had Google music going off when I would hot the power buttonbtobturn off display and it was ina task killer ibaccidently installed something I had on USB drive for my cell.it had a setting to close all apps on display off or sleep.
Erica:
Thank you for your reply. Oddly enough, something along those lines may be it.
I've not modified my tablet much beyond rooting it. I've not uninstalled applications and don't have a custom ROM.
You mentioned that something might not be playing fair. I have no add on management application, nor any task killer I'm aware of. The Applications area of Settings has been doing what I need in that department fine for me. So I went in and looked at what services were running, and specifically turned off the services and programs I know I was not using: Skype, NemoPlayer, PhotoBrowser, Acer Sync. I then tried a sound file, turned off the tablet and it did continue to play steadily.
Now I guess I just have to figure out which program is the culprit, but it seems evident that one of them is.
Along those lines, perhaps you can answer something else for me: Those programs I mentioned above basically started running services on bootup. How do I stop that? I don't use NemoPlayer, for example, and so have no reason to have any service from it starting. I took a look at the Settings->Applications area and don't seem to see anything there that indicates what gets started upon bootup.
Thanks!

I use titanium backup. It has a option to not only backup. But can freeze apps.Im not sure but you might need to have root for this feature.there are other apps on market to freeze them maybe someone can help by telling the app they use.just do not remove any apps Acer put on your tab.
You can get root easky look in Dev area
Put some new information in teh original post.
My sound also cuts out when tablet goes to lock mode. I thought it was certain apps. Removed everything as far as widgets anything running in backround on home screen but I still have the same issue its random. Tried a clean wipe/install basic apps root explorer and still had it happen. I thought it might be a audio codec problem. In Honeycomb 3.0 I was able to play AVIs with AC3 in mobo and nemo player now I cant in 3.1.

Acer 4.010.02 Gen1
i have the probleme too with the sound when it goes to sleep when i stream webradio !
Just a thought, along similar lines when my screen is off sound will cut out after about 15 to 20 mins. I think for you as others have said you have something else that is causing the problem. For me I think it's just a system timer. Don't know how to fix it.
i have experienced a similar thing with some Roms I've tried and with them it was the built in overclocker that was the culprit. I had to change the profile in the overclocker to enable the playback while the screen was off. Same goes for overclocking apps such as setcpu.
I'm experiencing a skip with my email notification. I recorded a short notice (similar to you got mail) & it does a 5 second pause 1/2 way through. Didn't do it prior to 3.1

Nexus 7 extremely slow :(

I got my Nexus 7 in the first batch from Gamestop on the day of release. Initially, the performance was very fast, even faster than my Galaxy S2. However, after a couple of weeks now, it has become extremely slow. It is still stock, havent even rooted it. It is a 16gb model, and has close to 10gb free. I have tried clearing cache, closing all running applications, restarting but nothing really has worked.
The problem is almost every app is very slow. I get a notification of an email, i click on it and then stare at the white email screen for almost 10 sec before it opens up (the regular email app). It almost feels like a different device now than what i bought few weeks back. Other applications that run equally slow - Google Reader, Chrome, WSJ (this is perhaps the worst), Fluent News Reader. I am not much into games so havent tried a lot of them.Oh, and it is no match now to my Galaxy S2 Skyrocket or even HP Touchpad Cm9 that i got rid of last week.
I don't want to exchange it as it does not suffer from all the other problems being reported here (and am afraid that the new one might exhibit those). Please help.
Just a guess, but you most likely loaded something on it that is doing that. Check what you have installed on it, perhaps uninstalling some of the larger things to see if you can figure out what is holding it up.
Stock Nexus 7 Image
If cleaning the device does not work, you can always flash back to the stock image, which can be found on developers.google.com
Be sure to backup your apps and data!
or for the most simple of us...
Setting>Privicy>Factory reset.
That will remove any app that might be causing it.
Be warned tho, i think on this device it wipes the internal storage...
how is your WiFi signal?
seeing how almost every app require internet access, the delay could be it trying to connect.
Actually I thought that too... but my wireless signal is very strong in my small apartment and i have 30mbps line. I checked with speednet app and i am getting 13mpbs down, 4 mpbs up on nexus 7.
I am happy that this seems like my issue only - i will try to remove apps one by one to see if it helps or worst case, i will do a factory reset.
I was wondering if there are any known culprit apps responsible for memory leaks or something.

I have noticed how mine has been very sluggish when there are apps upgrading in the background or installing, etc. Maybe turn off auto update for play store?

If you send me a PM, I'll give you my email address and I can help you narrow it down by using screenshots of your app drawer.
install watchdog task manager lite, it monitors app in the background and tells you which one is causing problems.
have you tried turning off gps (location service) and see if hats the issue?
same thing

Just wanted you to know you aren't alone here...I have been seeing the same exact behavior on mine. I have started to uninstall apps one by one. I must be a bad app or something. If not I'm gonna wipe it and start over. It does feel disconcerting to go from easily the best tablet experience I have ever had to it becoming so sluggish.
i have the same problem, mine did the same thing on stock, ran great for a week or two, then became unbearably slow. so i rooted it and it wiped all data and the problem seemed to be fixed. then another week or two passed and its back to slow. i found out after testing with quadrant it has something to do with the i/o on the device, because the i/o score was abnormally lower than all the devices. putting a custom kernel will help, but still the i/o score is still quite low. i dont want to wipe all data again and if anybody knows a fix it would be greatly appreciated
nexus 7 has Kingston eMMC, it is better then the crummy Prime Hynix eMMC, but is eMMC none the less, not proper NAND flash/SSD
Well you could've had a bad app that is bogging your system down. A factory reset may be the only option so you can start fresh

Check the cache size of your Google Playbook or Magazine apps. It keeps downloading large files (400 mb) and may fill up your storage...causing it to slow down?
Having the same issue after owning it for two days. I really wanted to like this tablet,but between the sluggishness, and other various shortcomings, I'm going to be returning mine.
I deleted WSJ app and it seems to have helped a lot - not as fast as new, but a lot better. One thing which still irritates me is email app which just seems to be too slow...
Sorry to say but mine so fast I can't keep it down it trys to fly away lol

Same
has anyone been able to figure this out? I'm having the same problems and I've been running watchdog but there been no out of control process is on my device. I have wiped the device and the same thing just keeps happening after a little while it'll get very slow. it happens more often than not when there something in the background downloading are using the internet, but it's definitely not my connection because I've had no problems with any other devices.
Been getting similar behavior recently. cm10 euroskank, trinity 7.
Edit: in logcat, getting stuff like
I/Choreographer(10656): Skipped 30 frames! The application may be doing too much work on its main thread.
W/InputEventReceiver(10656): Attempted to finish an input event but the input event receiver has already been disposed.
I think I may have come across a solution. For me, the slowdowns were always connected to when something was downloading in the background, or when a process was using data, so I went through and turned off syncing on any non-essential Google services and other apps, and it seems to be working much better right now.

[Q] Note 3 - Alarm / Music issues?

I've had my Verizon Galaxy Note 3 since 10/13-10/14, pretty close to when it was released at Verizon. I've loved it, loved its tons of features, since I got it, and have had many people jealous. (I upgraded from a Galaxy Nexus, a heck of a reliable phone, when I realized that the Nexus 5 would also not go to Verizon.) In the past 6 weeks, i've encountered some curious behavior that i'm stumped and frustrated by. Overall, I love the phone.
Notes: I have searched and searched and searched for help, via Google and via XDA / AndroidCentral / other sites. My phone is un-rooted (never rooted), and has not been factory reset, dropped, submerged in liquids, or in any way mishandled. My phone uses the stock launcher and aside from some games, does not have a ton of apps installed.
However (Stated verbosely but with detail):
1) On two separate occasions, my Alarm has crashed. I used my Galaxy Nexus for nearly 2 years without ever having it fail to wake me (with many roms in between); I used my Droid X for nearly a year prior without ever having it fail to wake me, and before that my Blackberry Storm 2 for nearly a year without it failing. I'm not used to my phone failing me as an alarm.
In both cases, last Thursday (11/21) and today (11/25), I woke up to my phone acting as though the Alarm was still going off. (The notification bar indicated I should either Snooze / Dismiss the Alarm). I woke up about an hour after it should have went off, and there is absolutely zero possibility that I slept through the alarm going off that long. When I unlocked my phone, in both cases, it indicated the Alarm app had crashed.
I was using Timely on my Galaxy Nexus for the last few months of it as my daily driver, and then for the first few weeks on this phone. I immediately assumed it was the culprit, and went back to Alarm Clock Plus (the app I had used for nearly the entire time on my Nexus). This morning, Alarm Clock Plus crashed (with the 'Wait / Report / Close' options), and i'm now more confident that Timely was not the culprit.
In both cases, with both apps and on both days, after I clear the error, I had a similar experience.
- On Thursday, I pressed the power button to turn off the screen, and when I pulled the phone out of my pocket about 20 minutes later, it was completely powered off. However, I could not power it back on by pressing the button, and had to perform a battery pull to turn it back on.
- Today, I had pressed the button to perform a restart, and only tapped it instead of pressing + hold. Same thing happened: it turned off the screen but also somehow powered it entirely down, and required a battery pull to start it again.
- After Thursday's debacle, I have rebooted my phone multiple times, so it's definitely not because of an uptime related issue.
The only thing I can think of for the above scenario, is that I did have it work (the alarm) without any issues for a few weeks, and both issues (and some other random crashing of Google Plus, etc) have been following the update that was released by Verizon.
2) This is an issue i've experienced for the entire life of the phone, and is flummoxing me and extremely frustrating. I loved using the Droid X and then Nexus as my music player (both via headphones and definitely in the car via the Aux on my older stereo). On my Nexus I experimented with different Equalizers, including ones from Google Play (I liked 'Equalizer' quite a bit actually), and then I tried out and enjoyed Beats (or whatever it is now called, NexusLouder or whatever), to great enjoyment. Music sounded awesome.
On my Note, I expected at least a marginally similar level of audio (to that of the Nexus without Equalizer), until I rooted (which I have not done yet). I am facing (like others have sporadically reported) and issue where it appears that my Audio or Equalizer or something is turning off or turning on between songs. I'll plug it in to my car stereo, slap it in the window mount thing, and let it ride. It plays one track (sometimes two) without issue. Then, it will play a song either really quietly or really loudly. (I don't mean the volume has changed; it has not and I have verified this). The solution i've found is to go back (or forth) a track and then return to the same track, which has resolved this 100% of the time .... until a few tracks later. /rinserepeatrage
- I have tried this with the same Equalizer app, a few other Equalizer apps, and even without a Google Play Equalizer app (using only the built in one).
- On my Nexus and now my Note, i'm using Google Music, and use the pre-downloaded/cached songs.
- I have tried clearing the data / cache for Google Music and uninstalling / reinstalling it, to no effect.
- The only interesting thing i've noticed is that after the Verizon Note update (I believe), the audio appears to only get softer, rather than getting ear splittingly louder.
- Additionally, this seems to occur much more frequently when the screen is off.
Today I am going to the Verizon store and they will likely tell me they have to perform a Factory Reset (which is why I haven't already done one) before they'll give me another one, in the case that it is a hardware issue. I will very carefully be monitoring and see if this corrects / resolves either issue. I also intend to NOT install the update if I have any say (I don't know how not-rooted phones work with updates, i.e. if it is required or prompts for update, etc) If any of you have any ideas, solutions or suggestions, i'd be very open to them. I love this phone, but I absolutely hate that these two very important functions are not working consistently.
Well, i've been to Verizon and as expected, they heard my issue and thought that a factory reset might be the solution.
Their logic, which is not terribly shaky, was: the recent update (or even the factory pre-load of the OS) could have config or factory fragments / blahblahblah that a clear of the data / cache / etc could resolve. This made sense to me.
After the reset, we tried to recreate the Google Music bug in the office, no such luck, all looked good on the home front. I tried a few more songs on the way home, still not able to recreate the issue. I got home, all my stock apps updated, then I went through and installed apps, blah blah blah. I also cached the songs for an album so I could continue to confirm my confidence in this as being resolved.
I then went for a drive not too long ago, and the issue occurred again. I also noticed (though it may have existed prior to the factory reset) a new issue / symptom. When I scrub, like clockwork, the issue shows up. Song plays perfectly, I scrub (even only a few seconds forward), equalizer is gone and the music is much quieter. I have no clue what to think now. I will be hesitantly trying to recreate the alarm clock bug over the next few days. I also may try the old 'uninstall apps until I can't recreate' method too, for at least the Music bug.
If any of you all have thoughts, that would be extremely appreciated. Else, i'll keep reporting info as I get it, maybe this will help someone else.

Sorry to hear that! I know i've seen other reports on the interwebs saying similar things, but did not see any threads with discussions about theories or investigation, beyond the 'me too' I see often (which is entirely fine, and unfortunate for those who also have this issue!). Having the volume helps a ton, but i'm surprised I didn't see more analytical or critical thinking / discussion happening in the many threads, and figured i'd just get the ball rolling and hope this helps others (even if it's just mostly me putting findings down).
That said, I have more information to offer.
1) Alarm - Day 1, following the Factory Reset yesterday, it started without issue (not unexpected). I expect that the issue (if it does) will re-appear sometime around Friday - Saturday.
- Other than installing some apps (as mentioned previously) mostly things like Netflix and some games, I have not installed anything that (from what I can see) should interfere with an Alarm app
- I am presently using Alarm Clock Plus (the second of two apps I encountered the issue in); this is for consistency, and also because the app worked without issue for over a year prior to this
- I have not 'Turned off' any apps, though previously (prior to the Factory Reset) I had turned off some apps mentioned in other XDA threads as not required by the system to run (mostly Verizon and Samsung apps)
- I am not and have not rooted this phone at any time; this is 100% stock Android at this point (well, as Stock as a Samsung phone gets)
- After speaking with a few friends, they have confirmed that: this issue has occurred with the stock Alarm Clock app and another 3rd party app (one I have not tried yet) as well; but one friend has not experienced any Alarm issues at all (though he may just not be aware of them, so i'm taking his account with a grain of salt)
2) Music - To add to my previous notes about the issue around the equalizer ..
- I am able to (as indicated previously) re-create the issue on-demand by scrubbing
- I can re-create the issue relatively reliably by hitting 'Pause / Play', and I didn't see a difference (in ability to reproduce) whether it was from the lock screen or in the app that I hit 'Pause / Play'
- It does appear that (with inconsistent results) I experience the Equalizer turning off / on by itself, if I keep listening to songs the issue seems to reverse. (i.e. Song 1 is fine, Song 2 - Equalizer turns off, Song 3 or Song 4 - Equalizer turns back on) I encountered this just a bit before this post, and sure enough, after hitting 'Pause / Play' I was able to verify that the Equalizer had turned back on.
- I am now 100% positive it is the Equalizer being horked by the phone / OS / something. This is based on replication of the issue (where it sounds like it gets soft) being the exact same sound as when the Equalizer is just turned entirely off.
A few things to test today / next few days:
Alarm issue:
-None at this time; keep observing
Music issue:
- Google Play Equalizer app (see if issue occurs still outside of the stock Equalizer)
- Try non-Cached music to see if this is a factor (including 'Pause / Play'; song scrubbing; etc)
- Try an alternative to Google Music (this is not a practical solution to me, but would provide comparison data)
Last note:
- After completing the Factory Reset and hearing my story yesterday, the Verizon rep did inform me that I could bring the phone back, if the issue keeps happening, and exchange it for a refurb. I'd rather avoid this if possible, as I feel like i'm not as confident it is a hardware issue as before, but this is an option (and may be an option for others wishing to try this path). Obviously, I hadn't rooted, so the Manufacturer's Warranty was available, so YMMV.

- Try an alternative to Google Music (this is not a practical solution to me, but would provide comparison data)
Last note:
- After completing the Factory Reset and hearing my story yesterday, the Verizon rep did inform me that I could bring the phone back, if the issue keeps happening, and exchange it for a refurb. I'd rather avoid this if possible, as I feel like i'm not as confident it is a hardware issue as before, but this is an option (and may be an option for others wishing to try this path). Obviously, I hadn't rooted, so the Manufacturer's Warranty was available, so YMMV.

My stock alarm crashed yesterday. Woke up to a completely black phone. Only the pulldown would get out of the crashed alarm app. Quite unfortunate. 100% stock, unrooted.

Sorry to hear that
On a similar note, if anyone can re-produce the Music issue i've mentioned, that would help me confirm i'm not crazy or alone in my issue.
Of note:
Music:
- I have attempted to recreate the issue in Pandora, but was unsuccessful. The audio remained unchanged when I did a Pause / Play (I was unable to scrub, unsure if that's a Premium feature or just not a thing with Pandora). I will not be able to try a local song with another music app until I am home this evening.
- I was able to recreate the issues (scrubbing, between track loss of equalizer, pause/play) with the Google Play equalizer app 'Equalizer' reliably.
- I was able to recreate the issues (scrubbing, between track loss of equalizer, pause/play) using both Cached music and Streaming, with stock and 3rd party equalizer
After searching for awhile for an already open bug report, I have opened up a bug report on the AOSP site, in case you are interested, for the Music issue: 62864 is the defect number; I am unable to link it since i'm still not yet a real boy.
I will hold off on creating one for the Alarm issue until I am able to recreate it post-Factory Reset.
This will likely be the last update until post-Thanksgiving, and will hopefully bring a measure of consistency (if the Alarm error returns) or confidence (if it doesn't) to the information I have.
Music:
- I was able to recreate the issue with scrubbing and 'pause/play' with a song located directly on the phone (not downloaded/cached via Google Music)
Other notes:
- I've seen other sites with similar sounding issues for different phones, such as the Galaxy S4, well before the Note 3 came out
- This is noted as being a bug with the equalizer, but not specific to the .api or .dll or whatever Android calls reusable things (as this is an issue with not just the stock equalizer, which points to some system dealie rather than the specific equalizer)
- I have not yet tested another app such as PowerAmp or similar, but suggested workarounds on the GS4 issue thread (on AndroidCentral) indicate disabling the equalizer altogether (not a great workaround) or using another app (not confirmed as a workaround; by me or the thread)
- One other forum suggests it is due to a bug in the OS with the equalizer not having a persistent icon in the notification bar, and suggests using another app (the 'Equalizer' app from Google Play is suggested) to resolve; this thread was started in May of 2013, but does point to it turning off during playback, not in between songs
- Still another person does report the issue I have experienced, with the issue displaying when the screen is off during the change from one track to another; this person also indicates WinAmp did not resolve this issue (implying that: A) local tracks are not the fix, and B) that another player is not)
Alarm:
- Day 2 after Factory Reset, the alarm went off again without issue
- I have had difficulty with finding many other threads or information; if you are reading this and have experienced this, it would be helpful for information to note that you have had it, and if you have the MJ7 update (or whatever) that too would help
- I might end up doing a bit of 'set an alarm for 5 minutes' testing and see if I can recreate the issue with any reliability
Learning is fun! Happy Thanksgiving and/or Hanukkah everyone!

My alarm crashed a couple times with my unrooted Note 3. After I rooted, no more problems with Alarm or anything else crashing.
My advice??
Root & load SafeStrap 3.65 HAppY Thanks Giving
Are you using any battery-saving apps? That could create issues like this, especially if the app messes with wakelocks.
I am rooted with the stock MI9, and alarm crashed one morning. Apparently there is a bug, root or no root. All I had to was restarting the phone and it worked after that, but it may crash anytime, I'm afraid.
Sent from my SM-N900V using xda app-developers app
Update (12/2):
So, after a Thanksgiving break and more time for more research...
Alarm:
- Since the Factory Reset, I have not had the alarm fail
- From Thursday Morning to Sunday Morning, I did manually / individually set an alarm for each day; unknown if this is a factor
- I do not use any power saving anythings (I don't even use the built in Note power saving mode)
Music:
- Audible (the Amazon Audiobook App) did not display this behavior
- I have not had a chance to try to uninstall until I cannot recreate this
Related to above?
- Once more I set the phone down (this time after using it very liberally for the past few days, and then on an 8 hour drive home yesterday) on a coffee table, not hard or anything, and it would not turn on
- Weirdly enough, although the power button, home key (or whatever the physical key in the middle of the phone is called) would not turn the screen on, but when I pulled the stylus out (on a whim), the screen turned on but was not responsive
- Battery pull resolved this, but I never saw any errors / errored apps / etc
- I am more firmly believing that at least this part is related to a hardware issue and will be going to Verizon tonight for my Manufacturer's Refurb or whatever
Notes:
- I am not using any crazy apps, mostly games and such, all straight from Google Play and none are those obviously suspect apps (like the many strip poker, etc, that are very shady)
- Although I have a decent volume of apps (probably about 40 or so from Google Play, not including the Verizon pre-loaded), I have fantastic battery life still
- I do not have any power saving anything turned on, on the phone, and do not use auto-dim, or anything like that
- Since the factory reset, I have not 'turned off' any apps
- I do have a Sandisk Ultra 32GB microSD card, this could be a factor
- I have a Model: SM-N900V UD (in case the Refurb is a different model)
That's all for this update, will keep updating as I have more information to share. (Still assuming that at least someone is finding this helpful, if not, i'll keep playing quietly in the corner)
More updates -
Alarm:
- The Alarm functioned without issue once more this morning (this time the result of a recurrent alarm, and not a manually set alarm)
- I am beginning to suspect that after the latest OTA, it gummed up something and just required a Factory Reset to un-gum
- The alternative is that the issue with the unresponsive screen is related, but the times I experienced the Alarm issues were accompanied with an error indicating the Alarm app had crashed
Music:
I played around with a few settings and did some app-investigation and learned stuff.
- I DO have 'All Access', though i'm unsure how that would impact the equalizer
- Surround vs. Stereo does not make a difference, issue is still present
- Adapt Sound On does not make a difference
- Adapt Sound 'Turned Off' does not make a difference
- Having the S Pen out does not make a difference
- I went through and wrote out every single app installed on my phone, Google, Samsung, Verizon, Play, etc ... and found a total of 356 apps. The breakdown was: 326 Pre-Loaded/Verizon, and 30 that I installed. I have uninstalled all but about 5 apps (Alarm Clock Pro, Business Calendar, Facebook, Outlook.com, A Better Camera, and Safe In Cloud) and the issue is still present
- I cleared the Cache / Data and 'reverted' Google Music to the pre-installed/factory installed version: v5.1.1107K.753159 and after this was completed, the issue was NOT re-creatable (at least the 'scrubbing' part)
- I re-installed the most current Play version: v5.2.1301L.891271 and the issue was NOT re-creatable (at least the 'scrubbing' part)
- My working theory is ... well, no, I don't really have any idea now; I thought the version could be an issue, but that doesn't appear true. After the Factory Reset, the version would have been reset as well, but the issue returned, so maybe it takes time?
Note:
Due to the other mentioned issue (where I set my phone down and it randomly is unresponsive) I will be receiving my Manufacturer's Refurb on Wednesday-ish (depending on whether or not FedEx tries to deliver when i'm at work or not). The hope is threefold: 1) that this resolves the issue with the random unresponsiveness, 2) this resolves the issue with Google Music, and 3) this resolves the issue with Alarms. This would confirm a hardware related issue as being the source of all three, but if either of the other issues return, this means one of two things: 1) the issues are software related, or 2) the statistically unlikely but possible situation where I received two bad units.
To any readers: I've asked before, but figure i'll ask again.
1) Have any of you experienced the issue with Google Music's equalizer shutting off when scrubbing, in between tracks, or similar?
2) Have any of you experienced the issue with the Alarm not going off, AFTER receiving the latest OTA?
3) If you have experienced either of the above issues, have you performed a Factory Reset after the OTA?
Update: 12/5
Alarm:
- No issues since the Factory Reset still
- Really starting to think the Factory Reset was the key
Music:
- Still all kinds of things going on; tried another reset to 'stock' Google Music but issue came back
- More research seems to find this issue with other 4.3 phones like the Galaxy S4, etc
Notes:
I have now received my Manufacturer's Refurb. I'm about to go through the process of the switchover, but I wanted to note something I found interesting. On the sticker behind the battery, (where the IMEI and all that business is), I noticed one difference between the one I bought in the store and the refurb.
Model is unchanged, so is SKU and FCC ID. Right below 'Made in China' and above 'IMEI' I see a number. On the one I bought was '13.09', but the refurb is '13.10'.
Does anyone else have any other numbers? Is that a revision or something like that? Just wondering if that could mean another run of the hardware or something. Or if it's nothing of course, whatever.
I'll update again once I have more info from the refurb. /crossingfingers
I have the same problem. I have had my Note 3 for a week, and yesterday a third party alarm crashed (Sundroid). Then today, the stock alarm app crashed. Do you use a widget for your alarm? I do. This is stock, unrooted, very few apps. Is there more information I can give to you?

Good questions I do not use a widget, and with regard to the Alarm, I think the one big question is: Have you received the MJ7 OTA? (If you go into About Phone and look at Build Number, the last 3 characters tell you if you have the latest OTA). If you do, I would suggest a Factory Reset, which is painful but appeared to resolve the issue for me.
Updates: (12/6)
I have received my Manufacturer's Refurb and have completed the process of switching over (including a Factory Reset after the OTA update). I am still curious what the 13.10 means on the sticker with the IMEI (since my previous phone at 13.09).
Alarm:
- The alarm worked without issue on Day 1 with new device
- All signs right now point to: If you have Alarm issues, and have received the MJ7 OTA, perform a Factory Reset; seems to resolve it
Music:
- On the Manufacturer's Refurb I was able to quickly confirm the presence of the bug
- This is looking more and more like an issue with either 4.3 or some Samsung software issue
- I would suggest submitting a bug report to Google and also posting a review on the Google Music software, see if we can get Google to look into it
Thoughts:
- Is there a Google Music .apk for 4.4? Does it require Root to side-load if so?
- I wonder if anyone with a Nexus 5 (or other device with 4.4) can recreate the issue
I didn't read thru everything here, but I use Alarm Clock Plus (the paid version) and it has never crashed once on me.
I bought my N3 the day they where released and used it everyday on first the stock ROM & now Beans ROM..
I am on the updated mj7 firmware etc.etc.

How long ago did you root it? I'm assuming you performed a factory reset or a cache/data clear (or similar) as part of the rooting process, so i'm leaning towards that being the reason it has been stable. That said, if my theory holds that it is related to the MJ7 firmware and needing to be cleared out or whatever, that also means that it likely wouldn't be affecting everyone.
Are you able to replicate the issue with equalizer? I hadn't thought to ask if Rooted users experience it too.

When the mj7 tar was released, I did an odin flash of that to reset everything in my stock ROM slot.
I still had beans ROM in slot one with safestrap and it didn't affect that.
I have had no music problems whatever, but I use WinAMP with the viper sound mods. I have 800 gigs of music on my 64 gig card that I play thru headphones or hdmi out in my truck.

Unfortunately, i've already heard that a good way to resolve this issue is to install the Viper sound mods, but was hoping to prove whether or not Rooting / Rom-ing it (without Viper) made a difference.
Of note -
Music:
- I turned off the equalizer entirely, figuring i'd just deal with it with a more flat sound, and after playing 2-3 songs, the music got really loud; after doing a pause/play, it went back to normal. I verified (before pause/play) that the equalizer was still off
- I am still unsure why my friend couldn't recreate this, as if it is a software issue, any Note 3 should be able to recreate it

Heavy lag

Hi guys,
Has anyone noticed heavy lag and freezing when using the phone. I don't have a lot of apps installed and i have disabled most apps that i don't use and the phone is still giving me issues.
Any advice is appreciated. [emoji4]
I switched from RAZR MAXX HD and this phone is a space rocket in comparison to my old Droid. Have you tried factory restore? Then if it lags - I would try to return it to Moto.
Check CPU utilization. Maybe some app hangs on. I've noticed that noozy (music player) lags like hell when album is over and player remains in notification bar.

I have the same problem, I tried to removing as much as possible automatic start calling but often when I uncheck the receiver this puts me "failed" in Rom Toolbox, I have tried Xposed Auto Boot module, but I do not feel that it works.
But for me, I have a lot of app instaled and my UI is very modified (Nova Launcher, Gravity Box, various Widget), so I know why he lag, but I still find it overheating lot and that's what most do slow.
Hi, I am having same issue. My configs was same as you, @Trinytix, but I had uninstalled all of them because lag issues. And now I continue to have same lag issues. When I use the standard cam for five minutes it become freezy and lag and sometimes I lose some photos. All the time it is burning. Just stops to burn when I leave it without work about 30 minutes. I think the problem is the snapdragon 810 but in other foruns some say that the problems with this processor was fixed.
I've been having similar issues, I got really into theming (using nova prime) the last couple of months and at the end of January the phone started to really lag hard. A couple weeks ago I stopped being able to open any apps other than the phone and google's messenger. I tried to factory reset from settings and could not (device gets stuck un the power down sequence), so I went the recovery mode route. reinstalled a fraction of my apps, put back a much stripped down version of my theme, and things were mostly ok, if a little laggy. However, the phone insisted that there was no SD card (internal or external) despite there being a 64GB card, which would sometimes show up when viewed in settings, some apps (podcast addict) were able to access the internal memory, but others couldn't (cameras, sms, photos, music). Yesterday the keyboard ceased to launch for more than a split second at a time, and would not take any input (you would not believe how infuriating this is unless you've experienced it first hand). In an attempt to regain some functionality I started uninstalling everything that I don't consider vitally important (bus app, podcasts, messenger) couldn't get through more than 1 or 2 at a time because multiple windows would stack telling me processes like "motorola" "android" and "media" had stopped. I did succeed in stripping away all the automation apps and theming apps (tasker, nova, icon packs, etc). I can't even place a phone call on the first try.
Oh and to add insult to injury I have to darned green lines about 0.5cm wide now.
Looks like hw problem or system got corrupted. Try to re-flash whole system but if is hw...

Android 10 stable UI lag

Hi,
I've noticed a UI lag when switching between apps or transitioning from an open app to home screen. This didn't happen in the Android 10 beta rom. Anybody have the same issue? I clean flashed the stable android 10.
I can confirm this issue in the stable release. But I would like to add that this lag was already in the beta release and is in my testing not app specific. I would clear the cache and make a reboot.
Go into developer options and disable the three animation types. Everything runs MUCH faster with them off.

I have, and while it does suppress animations, it actually feels less polished. And anyway, it does not resolve the UI lag which is really visible when using th app switcher. It's dropping below like 10fps. As if some gfx acceleration was disabled or the phone was completely overwhelmed
Anyone found a fix? I experience the lag every once in a while, though it's prevalent enough to be annoying.
I am having this literally every time i use the alt-tab like feature. Oneplus managed to **** up the one thing (butter smooth) Google has been bragging about for several versions ???
A simple fix would be toh format device once, as I have clean flashed and I don't face any lags

Turn off auto brightness .. maybe it can help
I have been reading up on the A10 stable release posts and I saw a lot of people mentioning the issue that you are talking about here.
Many of them suggested a full format. So basically setting up your device as a new device.
I cannot confirm if this works for everyone but a lot of people are saying that after a fresh install they are not facing any issues.
All of the points mentioned above are just what I read from xda and op forum posts. I personally have not made the switch yet and probably wont be doing so soon.
Hey guys. I encountered the same problem on my Nokia 9. Not quite sure why this error doesn't get noticed by more people.
I think I fixed it for me though.
In my case it seemed that the OLED always on screen (which shows notifications and the time) was the problem in my case. It would always show that there are notifications even if there weren't any and that started adding up. So while the rest of my phone ran buttery smooth, the notification bar and lockscreen began looking like a Diashow. 2-5 fps sometimes. What I think is happening is that all these notifications are buggy and the always on screen can't get rid of them.
So my fix was turning that off and then restarting my phone. Since that everything runs smooth again.
If there is another thread I should post this to please tell me but I only found this one.
Hope it helped.

I think the issue is just : it's a ****show of awful coding, optimisation and non-existent testing. If manufacturers' programmers put in half the effort debugging their software we as "powerusers" at xda/reddit/... put twisting our brains in and out trying find correlating explanations and workarounds as to why we get UI lags or other absurd bugs (like 5GHz wifi not working anymore) on the 10th ****ing iteration of Android, we wouldn't have all of this. It all boils down to the general idea that because it is consumer grade product, quality check is just a non-subject. Apparent quality is just enough at product launch, and further updates (if they do get round to releasing them) can brake everything without manufacturers being held accountable.
The update showed up on my phone on the 25th, but, I'm NOT updating. 9 is too damn stable for me, & I don't see any "features" in 10 that will benefit me.
After reading all this i am not going to update to 10. Yet happy with 9.17.

Narrowed down some parameters
I have the OnePlus 6, and have similar issues, that include swapping apps being slow, but not just the swapping of apps, any app that has typing in it, seems to DIE when I start typing. Maybe this is a google keyboard issue or something? I notice the issue most in the Microsoft Teams mobile app. It also tends to only happen when at least 2 apps are open, if it's on it's own, it seems to do fine.
This might just be coincidence but I went into dev settings and turned on "strict mode" and now I can't get it to lag like it previously did.
I just looked at my running services (dev options > running services) and saw that my Bluetooth was using 2.2GB of ram, and youtube was 1.7GB of that. I toggled bluetooth off, then back on and it reset this. I have not modified the strict mode setting above... still have not had any lag, will update this thread if I do get more lag.

Lagging issue I've seen many reporting in xda on the stock rom OOS 10.3.0. But 5GHz is working as expected. I can confirm it because I'm using 5GHz WiFI now and then

After a night/day of normal testing with this, where I would normally have issues, I have not had and of the lag I mentioned above. This seems to have fixed some things. So, I would suggest that you first check to see what running processes are using all the ram, and then turn on strict mode in dev settings, if that doesn't solve your issues. I also have Ram Boost option turned off.
I experience the FPS drop quite often after the update. It's especially noticable when scrolling pages, switching between apps, pulling down the upper panel. The slowness seems to disappear temporarily after closing all apps. But I can't say that some particular app causes the lag.
UPD: A simple test to recreate the problem. I push the square button to switch between apps. Start swiping finger left-right and watch the animation smoothness. After 5-10 seconds comes the wave of low FPS, which lasts for a couple of seconds. Then the process repeats. The slowness doesn't seem to depend on some exact apps that are open.
UPD2: Well, I've just found out that the problem isn't constant throughout the day. There must be some connection to applications running in the background or something like this.
