I apologize if this ends up being long winded, I want to lay out all the details.
So I recently purchased (what I had believed to be) second hand Nexus 6P. It is in perfect physical condition however, no signs of ever being used. Battery is great, performance is great, speakers are great, camera amazing, and screen is perfect. However two odd things started to occur which I believe stems from the same issue. When hanging up phone calls the hanging up process would hang for a long while and either eventually hang up or the system would soft reboot. After reboot notifications are still set to priority only "call management", although it is easy to adjust and bring it out of that. However no audio/mic works at all (Play Music and YouTube give an error that they cannot play). No audio from speaker, or from headphone jack. I could however connect to a Bluetooth speaker and audio plays just fine. I then went to do a proper shutdown of the phone (using the power button menu), and when I manually booted it back up all audio works find again. I plug in headphones and start listening to music on Play Music. After a while however, playback fails and all the audio on the phone is once again dead...queue soft reboot. And repeat the whole process again. If I'm listening to headphones and I do anything to activate the microphone, audio crashes and go through the whole process again.
So I decided to make sure it was all up to date all the way to OTA 7.1.2. Once I did and I tested, the same issues above occurred over time. So then I thought maybe if I used Nexus Root Toolkit and did a full manual wipe and reinstall of 7.1.2 factory image from Google. Phone issue initially went away, but audio playback through headphones persisted and eventually the phone issue manifested itself again.
Today I decided that I do a full wipe again and try and install Pure Nexus 7.1.2, non rooted with BeanGapps and vender image (following the entire process here to a T.) I have not been able to replicate phone issues, however the audio playback and headphones issues are easily repeatable.
TL;DR - So this leaves me with a few things;
1. I can use the phone by never connecting it to external audio source perfectly fine, no problems at all.
2. Phones calls may sometimes get stuck at hanging up, and the result is a crashed audio system.
3. The only way to temporarily solve this issues is to shutdown via holding down lock button and Power-off using the menu that appears. And then manually starting the phone back up again.
So I'm not sure if this is a hardware or software issue. The fact that it persists between full wipes and reinstall of different roms makes me think it to be hardware. Although the temporarily fix of proper shutdown and manually start back up makes me think the OS/Kernal is somehow "clearing a buffer" or something in it's proper shutdown process. Which without doing leads to the audio system being completely down. Therefore on soft/dirty reboots the audio system is still down.
As an added bonus my sim card was a Micro SIM, before I opted to take the scissors to it instead of buying a nano sim. It works (so I thought), it just doesn't fit in the tray quite right. I tested recently with a proper nano sim from a different phone, and everything worked perfect. Then I swapped my franken sim back in and...it worked perfectly fine.
I did search for this issues in previous posts but all I could find was this. The issue (s)he describes is exactly the same issue as me, but his/her solution does not seemed to have worked. I am inclined to try doing a full wipe again and flashing completely stock older version though.
Any help, suggestions, etc are greatly appreciated. And thanks to the developers of Pure Nexus, it seems to be very polished and I'd love to use it daily driver.
Since you are having the issue after a clean install of stock and a clean install of Pure Nexus I don't see how it could be anything but a hardware issue. You could try to flash a custom kernel if you really think the kernel is an issue but I doubt that it will do much good. You could also try a clean flash of a different rom (I recommend Dirty Unicorns which is very smooth and stable) but again I doubt that it will do much good since you seem to have a hardware issue. You might have bad memory which is getting cleared when you reboot the phone.
I fear you may be correct. When you talk about bad memory, I don't want to misconstrud what your trying to say. Would there be a buffer for the DAC for example that is bad? Or do you mean the RAM or the flash memory itself?
It is very disappointing. This phone is perfect otherwise. I'd like another 6P, but I am concerned I then get one with battery 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.

Hi Friends!
I am having a strange problem in my samsung galaxy s4 (Gt-i9500).
I was on stock 4.4.2. Unrooted. One day suddenly my Device is muted. Means no audio on music/video Player. No audio on notification. No touch sound. No screen lock sound. No sound on call. Caller can't hear me too. No sounds on headset too.
I tried reboot, reset, format, removed SD card, Flashed Stock firmware in Odin, Flashed Custom Roms but nothing worked.
Visited Samsung service centre . They tried flashing the firmware. Then said they need to change the motherbord. Because my Device is out of warranty they said it will cost me around Rs 7000/-. I don't want to spend that much because i know that this is not a hardware problem. How do i know that??
Now the intresting and strange part of the problem. Every time When i switch on my Device in morning sound works properly. Everything works including calls. There is a small lag in calling interfere. When i touch mute or Speaker phone there is a lag of 1 or 2 second in activation. Same while receiving calls. But Sounds works perfectly. For weeks . UNTIL i reboot or switch off. After reboot again same problem of no audio.
To solve this i have to switch off my Device for a whole night and switch it on in morning. Every time this works. In every ROM this works.. I wonder what is the reason behind the problem and solution.
Please help me to solve the problem Permanently .

He said that he flashed custom roms.
I don't really know what to say since it happens on different roms. That means it can't be a software problem. Unless it's cause by software unaffected by flashing other roms
You have clearly established that it is a hardware issue because you are getting consistent results in software across roms. Everyone else can state to you most highly elusive issues in roms are solved by clearing dalvik cache and factory reset and in extreme cases deleting user data from the recovery. That hasn't worked so it can't be a software issue. Your audio processor is even lagging as you say even when it is operating within its manufacturer specifications in a newly installed rom. Unless you can trace back what you could have changed unknowingly on a hardware level, trying to do it on a software level is futile, its not meant to be as complicated as your thought line makes it. Surely..... you took it to as Samsung Service Centre, unless you can prove that you ran hardware lab tests showing clearly that your individual audio hardware components aren't failing by showing that they are yielding manufacturer hardware specifications at every test, you are going round in circles.
Hardware failure occurs on 3 levels:-
1) Total instant failure with no temporary workarounds
2) Noise suppression failure (Introduction of noise)
3) Waning hardware performance.
Yours seems to fall in the 3rd option. The unfortunate bit is that the audio hardware processor is located on the larger board (motherboard) as a fused component and not on the easily replaceable flex daughter board below the speaker. Unfortunately you might end up forking out that Rs7k eventually. Samsung should have designed the phone in such a way that you don't need to replace the entire mobo for such an issue.
That's the detailed and informed explanation. I am impressed by your knowledge. Thanks for replying .
Nexus 4.
Android 5.1.1
Kernel version 3.4.0-perf-gdffc258
I have had this phone for over 2 years. For last 6 months it has given some problems.
I had an issue 3 months ago where it would stall at the welcome screen for Android.
Factory reset worked on this occasion.
NOW I have major issues with
1. No sound heard. (neither speaker nor headphones)
2. Using the volume key slows the systems right down and no effect on sound (i.e. still cant hear anything)
3. Whatsap call cant be placed or received (if i try it hangs the system)
4. Normal phone calls have the same issue but I can still hear sometimes and the mic also does work but interrupted and laggy.
5. Youtube open but does not play video or audio at all.
6. Spotify can play but no music is heard
7. Screen dims out at times totally
8. After reboot it gives error "Launcher is not responding" . I use the basic version no fancy launchers.
I HAVE tried clearing the cache and resetting to factory but nothing works at all !
Is this a hardware issue or software ? Any tips how to fix it. Thanks
Possible loose connection inside the phone? Was the phone ever dropped or exposed to moisture?

It has been dropped but not from a great distance and also it has a good case. It can be that there was some problems with moisture given there was incessant rain recently and I might have used it for a sec or so.
Would such a problem cause even the software to be slow or hang ? (like whatsapp, calling, youtube)
What do u suggest in this case ?
Did the problems appear shortly after the drop or after slight exposure to moisture?
I suggest removing the back of the phone and check the moisture sensors and look for residue on the circuit boards.
Before doing troubleshooting on the hardware, I would try a full flash back to pure stock lollipop and KitKat, to see if that solves the problem. If that is a no-go, then it would be time to inspect the hardware.
Thanks ! Could u please point me to as to how to get it back to pure stock Is. Thanks
Hey guys! I am not able to listen to music or open youtube videos or even do anything related to output of audio of my phone. On Google play music, I get "Couldnt pay tax requested" and on youtube I get playback error. I am not able to make calls as well.
I have flashed numerous images and the issue still persists. If anyone could guide me towards the right direction that would be great.
I bought the phone 7 months ago and suddenly this incident took place. I was running stock 7.1.2 when this happened by the way
Thank you for the help.
First of all, 7.1.2 is a Beta stage not a release.
Second, If you can have sounds on other options such as ringtones and so on, then it is an OS issue and a clean flash might solve it.

Thank you for the reply.
No sound from Ringtone as well. Like no audio is playing on my phone at the moment.

So how can you tell if it isn't a hardware issue and not Android problem?
I haven't heard of what you are describing as being a known bug in 7.1.2. You can try a factory restore but personally I would do a clean flash of the latest stable Google image and see if it fixes your problem. And I would use the flash-all.bat command like Google suggests rather than flash all the parts individually like the Heisenberg guide on XDA tells you to do. I don't suppose you are running any audio mods on your phone? And you checked the obvious? Your phone isn't in Airplane Mode, Do Not Disturb isn't activated, sound shows the various volume levels aren't at 0?
Having same issue, no audio at all from speakers, cant play youtube / googleplay music or videos, headphone jack does not work eighter, wont even detect the headphones, soft reset/ hard reset wont work, havent tryed out rooting and changing rom or reverting from 8.0 (currently running), apart form audio everything works fine, im still trying to figure out warranty as its still in its period, but without proof of purchase they are beeing jerks so far, so im rooted with some ideas is ive had previous experiences with phones, might it be possible for audio drivers to go missing or messed up? or should i take it to a repair shop and see how much theyll ask for it? or shuld i just upgrade to something better and let this brave hero die alone, maybe use as hotspot in my car haha
Hello.
My friend got a nexus 6p one year ago. One month ago he started to have problem. He was on stock rom
-First when he pressed the touch screen he heard small weird noises (hard to describe)
Then progressively :
-Speaker stopped working
-he could not play youtube video in you tube app : a weird error message (every time different) appeared. Gallery videos don't work as well
-But weirdly enough video played in the web browser including youtube videos, works, still without sound.
-He cannot make calls
-Jack plug doesn't works either, but he can use his Bluetooth headphones
We tried to install a custom rom (lineage os). We succeeded, but the above problem appeared again.
Then we flashed the factory image [url]https://developers.google.com/android/images[/URL] for nexus 6p. We also succeed but the above problem appeared again.
Thanks in advance for your help

The 6P has two speakers, and they wouldn't both fail at the same time. Sounds like he's damaged the phone somehow. The audio jack and speaker output both not working seem to back this up. I've seen the headphone jack part available separately, and there are guides available to replace it. Before flagging it as a hardware issue and opening the phone up, you want to make sure you wiped the phone completely by formatting the partitions (system, userdata, cache) and use the flash-all.bat included with the full Google image. There is a remote chance it is software related, but I doubt it.
You could always flash a custom kernel, use a kernel manager app to turn off the large core cpu and see if the problems go away. If they do its related to the build problem that causes the 6P to boot loop but those particular symptoms aren't familiar. It's still worth a try if flashing the stock image doesn't fix the problem.

Yes. You can always turn it back on but turning it off apparently fixes the permanent boot loop problem on the Nexus 6P. If the problems you are describing are related to the same build problem then turning it off might make them go away. Sometimes people's phones would start acting odd before going into the permanent bootloop. That phone could be on its way there.
this is purely a guess but the problem may be hardware related with the headphone jack. it could have a physical short somewhere. if thats the case the device may think a headphone jack is being used and wont play through speakers because its being told its plugged in. But wont play because of some physical short or an open.
