[Q] Cyanogenmod 11 slowdown - Galaxy S 4 Q&A, Help & Troubleshooting

I have been working with Cyanogenmod on my Samsung Galaxy S4 for a while now. Since a month or so, I am experiencing terrible slow down. I work fine when i reboot the device, but after a minute or so, still slow. I can't compose a message because the keyboard does not follow input, launcher takes a few seconds to switch pages, ... And the strange part, RAM usage is below half.
I tried using a stock rom after that, which worked fine, no slow down at all. Now I'm running Cyanogen again, and the slow down still happens. I switched from dalvik runtime to ART, no luck. Tried cleaning all caches, no luck. Does anybody have an idea? And is this the right place to ask people?

[Q] Nexus 4 Freeze and Crash

Hi All,
I'm currently experiencing a problem, that I know has popped up on this forum a couple of times, but not for the Nexus 4 specifically.(As far as I know....)
The problem appears to be random freezes, where the device just stops, screen freezes, no hardware or software buttons respond, and requires the power button to be held down for a few seconds to restart... It happens once or twice a day, at random intervals, mainly when i'm at the home screen or just browsing Chrome (Beta).... My Nexus is running the latest Nightly of CyanogenMod 10.1, build 20130529, although this was happening on the RC1 build too... Also running the latest franco.kernel 3.4.0 and Clockwork Recovery. Haven't partitioned, restored any backups etc as of yet. I also have about 230 apps, so if it could be software related, there's i high chance one of those has got something to do with it!
A suggestion or solution that doesn't involve fiddling around with ROMs, kernels and other stuff would be great, i'm not much good at that sort of thing and don't allocate much time to fiddling about with my phone, but nevertheless if required i could give it a shot....
Thanks,

Nexus 7 2013 random freezing

Hi guys i got some freezing issues, anyone got an idea what could it be? i'm totally new to Android/tablets, so other then this info, i don't know what else to say, or explain the issue better, it just freezing for like 5 sec, and after it works normal, its random freezing. I hope anyone can help me, thanks.
Is it when you update or install apps?
This is normal, the OS can freeze for a few seconds during write operations.

What ROM and kernel are you using? Are you over clocked?

No overclock at all, Kernel - 3.4.0-g9e52a21
Build number JSS15R all stock here. No custom ROM's..
I experience the same BS on an all stock WIFI model (2013.06 date code). Thought it was JB 4.3 teething pain but my Note 3 running 4.3 doesn't do it. Have mainly noticed it playing Great Big War Game where it'll randomly freeze the whole tablet once per launch for about 10 secs where nothing responds (show touch, home, switch task, etc.) then it'll either return to normal or prompt with dialog to wait or close. Have also had it happen in Modern Combat 3 along with the random app close that, again, doesn't affect Note 3. Haven't seen newer apps affected so perhaps it's a software issue and is fixable but it's irritating nevertheless considering it's a Nexus device and after correcting the touch issues with ts10 firmware update. Going to try reflashing the stock image to see if it fixes it otherwise looking forward to dumping this Asus for a Note 10.1 2014 LTE. My Note 10.1 2013 and Note 2 have been 100% solid with never a crash, hang or touch issues.
I had freezing problems when i was trying out the TS20 fix. TS10 seems to yield erratic behaviour randomly after each reboot.
Ever snce i've been testing the ones between TS10 and TS20. TS16 works better for me than TS18 - just being more responsive but both has no reboot issues. Am testing TS14 now and it seems better than TS16 but i needed more time to run it. None of the 14,16 and 18 has given me any kind of freeze after 24hrs of testing on multi-touch intensive apps.
You might wanna give 16 a try... i will be posting a more detailed update in sfhub's thread when i'm done with TS14 and TS12 testing.
Cheers
Thanks for the answers guys, but this is really new to me, i got no idea what is TS 14, TS 18 or TS16, can you guys explain me a bit? thanks.
I had the same issue. Please see my observations at post: http://forum.xda-developers.com/showthread.php?p=46082214#post46082214
However, I have recently tried to uninstall all apps (backing up with titanium backup) and installing back in bunches. With only the apps/games I use daily, the issue appears to have subsided, and I am trying to slowly bring apps back to see what the issue is.
Original post for consolidation purposes:
When it happens: Touch intensive Games (drastic, MMOJ, Dumb Ways) appears to be when the 3D GPU is NOT in use, netflix, when paused for a short while.
What happens:
1. Screen does not update display appears frozen
2. No response from nav bar icons
3. Power, volume buttons give no response.
4. If audio was playing right before it froze, it will keep playing as if nothing wrong.
5. If I hit the power button or the nav button then let it sit for a few minutes, suddenly it will react to every press I did in quick motion and go back to normal.
5a. I had show touches enabled, which showed a random number of the frozen touches working in quick succession when it "unfroze"
6. Sometimes requires a hard restart with no response.
When it started: Right before the Q update starting rolling out, did not have issues out of the box.
Purchase date and location: Right around the time of launch from best buy, 32 GB 2013 version
Troubleshooting steps: Safe mode (doesn't appear as often), full factory restore to the Q image when the R image started rolling out. Issues were gone for a short timeframe, then returned
Config information: Stock, latest firmware version, rooted via TWRP (latest version installed), and SU.
Observation: Appears to occur in select situations, and I believe I always have a GMAIL notification right when it un-freezes.
Let me know what you think and if it should be merged with a different topic, didn't see anything about it un-freezing when it was frozen or audio still playing.

Please refer to this thread for a fix:
http://forum.xda-developers.com/showthread.php?t=2428133
The fix from the thread above helps with many touchscreen issues including freezes.
At least it helped with mine. I was experiencing freezes and so called "sticky touches" (like when you short tap on something and the device interprets it as a tap and hold).
My device came with pre-Q and went through three OTA updates. After reflashing with factory R image minus wiping data (remove -w from flash-all.bat file) and with ts10 all appear to be better so far. Modern Combat 3 still randomly closes but it could be Gameloft's crappy coding. Need to run it for a few more days to confirm but reflashing factory R image with ts10 offer the best experience so far.
Mine does too now in addition to the already random reboot. The freezing happens when I try to input text on the keyboard.

[Q] Snapchat is slow as hell

So I've got a rooted AT&T Note 3. It's running the original ROM but modded like crazy. For the past couple of weeks, Snapchat has been horribly laggy. Every action takes a few seconds. The camera takes 10-15 seconds to load, and then freezes for up to 30 seconds before loading again. I have uninstalled, restarted, and reinstalled many times. Any ideas on how to fix this?
Nothing else is laggy or buggy at the moment on the phone. I have not subscribed to the beta either. When the keyboard finally loads in snapchat, it types fine. I've got a OnePlus One coming in a few weeks, but I'd like to get Snapchat working normally again until then.
Thanks in advance.

My Snapchat done this exact same thing, it was on my Nexus 5 though. I put it down to the ROM and /or Xposed (was using keepchat). Sure enough once I reflashed and reinstalled it worked fine. Not sure why it does this but it was the first time it had ever happened to me.
Try dirty flashing your ROM. And don't use so many xposed tweaks. See if it resolves, then wittle down which mod is messing with it.

SM-N900W8 & CM11 M12 bugs and issues :(

I have a Canadian Note 3 (SM-N900W8), it's KNOX 0x0 rooted and I have CM11 M12 installed. I have been using only the M builds since I got this phone, I didn't even set up Touchwiz when I got it, I rooted and installed Cyanogenmod out of the box.
Now, with the new CM12 builds coming out, what happened to CM11, are they going to fix the remaining issues? Or did they just bail on legacy KitKat users because I'm having TONS of problems and I don't want lollipop, it runs like absolute crap for the nightlies right now and CM11 M12 isn't much better. Bluetooth takes a couple of attempts to connect, when it does my phone runs super slow to the point it force restarts. For instance, if I'm driving around, listening to music on the car stereo, pull over some where, find a new album on Google Music, start playing that, it's all good, do this a few times, every time I use my phone it gets slower and slower until it force restarts and then bluetooth has trouble connecting again. I've tried this on a few other vehicles of different brands and aftermarket stereos and it's the same result.
Audio is all funky when bluetooth is on too, it sounds like robots for the system sounds and if bluetooth drops while it's connected the music starts playing from the phone and sounds all roboty. I always do clean flashes too and the latest Paranoid Android GAPPS every time I reflash, the ROM is fine out of the box, works flawless for the first few days but after awhile, it becomes so bad I have to backup, wipe, reflash, and start over for another few weeks.
Another issue is somewhere between M8 and M12 one of the builds corrupted my SD card, I tossed in a second new card, it was corrupted again, FutureShop won't give me another one and said my phone is breaking them so I'm SD-less right now.
There are also quite a few apps that force close, but always at random, it's never when doing the same thing over and over, for instance, I can be scrolling through G+ and it tells me settings has stopped working, wasn't even using settings, didn't even have it open, haven't clicked it since booting my phone, just randomly stops working for no reason, this also happens all the time with the Camera, it says it just stops working when I haven't even used it and then if I try to use it, it says the camera is disconnected and won't work until I reboot.
I turn my phone off every night while it's charging and turn it back on every morning so every morning it gets a fresh restart, and I have to restart my phone probably 5ish times a day, if I'm using bluetooth more then normal then there's quite a few more unintentional reboots in there as well.
The last issue, which is a known issue is NFC not working, is there a fix for this yet? I kinda miss this feature and with how flawed CM11 is getting I don't know where to turn since they always seemed to be the most stable out of everything I've tried.
Any before anyone says Temasek's CM builds, I tried it, the final for CM11, it was worse then M12, it's exactly the same as M12, but every issue happens more frequently. Also, the pull down menu (when pulling down from the top right to show toggles), the bottoms of the last row was cut off so it didn't look very appealing either, it also used WAY more battery life, I usually get a full day out of one charge, so around 18 to 20ish hours on one charge, with temaseks cm11 I had to charge my phone half way through the day, sometimes my phone would just die on me without me knowing, the battery usage was always Android System.
A new problem that just happened lastnight was Google Keyboard was deleted and only the voice search would work, but "voice search can't be reached" so I couldn't search for another keyboard app from the playstore. I also used the stock GAPPS so AOSP keyboard is replaced with Google Keyboard, I had to reflash again this morning because I couldn't figure out the keyboard thing, there wasn't even a keyboard under languages in settings so I had no options to pick which keyboard to use. When I reflashes this morning I used the Modular GAPPS to it keeps the AOSP Keyboard just in case this happens again but I'm getting really tired of only having a reliable phone for a few weeks.
So, are there any fixes for these issues?
Bluetooth taking multiple attempts to connect
Bluetooth forcing random reboots
Bluetooth making audio from device all funky and sounds like a robot
Corrupting SD cards
Random system apps stopping without me even using or opening them
Google Keyboard vanishing
Are there any stable ROMs I could try for the HLTE? Maybe one that has working NFC? I'm almost thinking of going back to stock *throws up in mouth* but I don't know what else to do with how many bugs there are and Lollipop is only getting worse with the issues.
I'm also trying to avoid Lollipop because everything is white, Note 3 is an AMOLED display, each pixel illuminates on it's own so white screens use WAY more battery life then black ones which was a feature of Temasek's CM11 that I liked, had the option in settings to make everything black like the good old days.
So guys? Really out on my luck here, not sure what the next step is, any fixes for these problems? Any other ROM's I could try? Would flashing a new recovery and reflashing CM11 M12 fix some of these issues? I'm using Xiaoli CWM v6.0.4.7(20140125). Would the fact that KNOX isn't tripped have something to do with this? I really don't understand why there aren't more posts for these issues which leads me to believe I'm one of the only ones experiencing them.
Any help or suggestions would be greatly appreciated
EDIT:
I forgot to mention that when recording audio or video, it's as if the mic gain is set on full so even the slightest sound is pure distortion, normal talking volume and it clips, I found an app that lets me choose between the mics and when I pic the external mic, it's all muffles as if something is covering it but my phone wasn't in a case while I was testing so I'm not sure what the deal is there but I can't record any decent audio with this and when I record in 4K using Cinema FV-5, all the videos turn out looking like Anaglyph 3D but all pink and green, it's really weird and I don't understand why, but 1080p at 60fps works fine.
I am on CM12 and luckily have had no issues at all. I came from KK 4.4.4 and still have the NB7 BL and modem. I tried one of the guys slim ROMs alpha builds but had issues (probably operator error) but I've tried Bluetooth, GPS, WiFi , LTE etc and everything is good. Not sure what to tell you. I do however always wipe internally and d/l all my apps again through WiFi. A bit cumbersome I know but it won't give me any residual data.

T-mobile s5 laggy

Hello everyone, I have an annoying problem. My device tasking very slow, camera, facebook, intagram, and almost all other apps, turns on take a log time, even quit takes up to 5 seconds. I tried few factory resets, flashed original ROM. Still have same problem. I think all the T mobile apps causes this problem, is there any ROM without these apps. For G900T. Or there any way to install G900F or other rom. Waiting for your answers, thanks
