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 guys.
I'm here to share a problem I'm having with my Nexus 6P: it often gives a crash randomly, needing to be restarted by force.
This does not happen because of a specific app and sometimes happens even at boot , when Google logo still not appeared.
I already using the phone about two weeks.
I received him with rom stock 6.0.1 and had the upgrade to Nougat available.
I thought the upgrade to 7.0 would correct the problem, but it was not what happened.
From the update I also felt that the crashes were more frequent when the battery was at a very low level, between 20 and 15% (as commented in a reddit threat that I can't copy here).
Following some recommendations that I found , I formatted the Nexus 6P with the factory settings to see if the problem returned.
Yes, it happened again.
I formated again and was gradually installing my apps to check if it was not a specific app.
I did it at last three times.
On these occasions, apps like Google Keep, Duolingo, ES File Explorer, Google Fit, Podcast Republic and even the Play Store gave the crash.
I formatted again and installed each app one by one again to try to identify a culprit and had the same results.
To try to work around the problem, I decided to go for a clean install of the entire OS with the latest build using the SDK (adb and fastboot).
Even with the flash of the latest build I continued to have this crash problem.
So I decided to go for custom roms.
I installed Pure Nexus and Sinless, and continued having problems with crash.
I tried to install the CyanogenMod, but failed. After flashing the rom, GAPPS and vendor image, the device crash in the Google logo.
My last attempt was to go deeper and replace the kernel as well.
I installed ElementalX (7.0) and Pure Nexus as ROM.
In the beginning, I still had many crashes, so decided to make some changes in the kernel ElementalX.
In a desperate attempt, I decreased the CPU clock all to minimum (1248 MHz).
Interestingly the crashes started to occour less frequently, but they still happen randomly and unexpectedly.
I have no idea if this reduction in CPU speed had any effect or was placebo.
What matters is that I'm still having crashes and I wonder if anyone has any idea of this solution to my problem.
Thank you guys!
PS.: the return of the phone is not an option. I'm in Brazil.
PS2.: sorry for my bad english.
Wow you have exhausted every idea... Return sounds like all that's left unless you wanna try putting the phone in the oven to see if it's just bad solder.

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.
I had retired my Nexus 6 a while ago due to the speaker issue that's been plaguing these devices. I decided not to sell it as it would be an issue for the next user, so I instead kept it in case of an emergency.
Certain issues have lead me to recommission the device, so I decided I'd see what's new. So far it is clear that there was never a fix, and some people swear that pressing on the speakers fixes the problem (whether temporarily or permanently). I never believed this as the only thing that seemed to fix it (temporarily) when touching the speakers is tapping on the speakers, but that seems to be related to the device rotating (which has also been known to let the volume go back up) and something within the gyroscope (something that some have brought up as well). My Nexus 6 unlike many others has the bigger problem where the volume will go down regardless of battery percentage, and it was terrible as there was never an instance in which I could truly use the speakers.
Reading around I have seen other "solutions" emerge, but never anything concrete. On a YouTube video's comment sections I saw one person mention that Franco.Kernel fixes this, for me this did nothing. On another forum I read a guy who said his issue stopped using Lean Kernel, and that it may have something to do with mp_decision. Unfortunately for me, I like to stick to the latest version that was officially released (in this case 7.1.1) and Lean Kernel doesn't seem to have made it that far. I gave up on experimenting for the sake of the speakers at this point and settled on my favorite rom which is Dirty Unicorns, using the final 7.1.1 build (somebody was nice enough to provide links as I could not find it anywhere and their official page only has their Oreo based builds). Obviously the speaker issue persisted here. At this point I wanted to see if there was a Kernel with good features and battery life and came across a thread that mentioned BL4CKB1RD Kernel. I flashed that and was a happy camper as my phone runs cooler (no difference has been made to my 4 hour average screen on time) and ultimately lag free. Reading the maker of the kernel's current set up using the kernel, I decided to copy it a bit by limiting my maximum CPU frequency to 2.5GHz and using said governor profile. I came across the mp_decision setting and turned it on just out of curiosity (I have no clue what it does). Later on, I went to watch a YouTube video and before I could connect my headphones, the video was playing...with perfect sound. I thought I was going crazy, so I let it play for a bit longer. No volume drop. I picked up the phone, moved it around, rotated it, blasted the volume to the max and still not a single drop. For literally an hour I watched videos and absolutely no volume issues. I decided to undo all kernel changes and reboot to see what would happen. Still no volume changes. I also decided to lock the CPU and GPU maximum frequency to produce more heat, still nothing. I played Subway Surfers which was a guaranteed instant volume drop, nothing. Rebooted several times more, let the battery die, speakers are still perfect. Could this kernel have fixed my issue? Maybe. It is also worth noting that before flashing the kernel, I ran a command via terminal emulator (requires root) that I read about BEFORE flashing the custom kernel, and I never rebooted my Nexus 6. The command can be found here (there was another thread that also included it but also linked to this thread):
https://forum.xda-developers.com/nexus-6/devs-only/speaker-amplifiers-nxp-tfa9890-research-t3236518
Anyone with the speaker issue should perhaps start by this command, reboot and see what happens. If not, try using BL4CKB1RD kernel and see what happens? If still nothing, try toggling mp_decision on and then test.

I just ordered a nexus 6, is this issue common? Does it affect stock rom or custom roms? I have a Moto X Pure at the moment, Nexus 6's brother, it has a similar issue where the sound cuts out when the phone is switched from portrait to landscape and vice versa but only affects custom roms. Its doesnt lower the volume though

For most the issue occurs at low battery, and the drop isn't major. I've seen some videos of people with this specific problem and I laugh because they don't know have it as bad as us with the major drops regardless of battery life. So pretty much the low battery volume issue is more common than the worse one, and you could say it is a common issue.
We had a white one that had absolutely no issues except a faster battery drain (perhaps because the speakers worked?!).

Yes.
For what it is worth, mp-decision is Qualcomm's own hotplug: it turns the processor cores on and off depending on need. I guess it may use other tricks as well, to optimize power / performance.
No obvious reason that it should affect the speakers, but you never know.
Does this thread address the issue with SEVERAL 8.1 ROMs I've used, in which the speaker phone does not function during calls... and during calls alone. I can play media just fine... IMMEDIATELY after the speaker not working on the calls. I CAN however plug a headset in and communicate normally . Just desperately seeking an answer or I guess I'll go back to 7.1.2
So now nexus 6 is running pie roms nearly perfect . Unfortunately this sound problem persists… it is truely fristrating
So is there any kernel that can fix it in pie roms? Thanks
I have been using my nexus 6 for a couple of years now and had the speaker issue about a year ago and went into recovery and wiped cashe and the. Did a factory reset. Did an OTA update and everything was fixed.
Last weekend I finally flashed TWRP and then rooted with Magisk. Went to install myself5's Bata version of Carbon room running pie... Not sure what happened but had error code 7 and bricked the phone. Had to wipe it out and went though Google to get an old OTA and reflashed and thankfully got my phone back. Tried the process 3 other times and got the same result. Each time no speaker issue.
The last time I tried it I left it alone and didn't even put TWRP on it but now the speaker problem comes and goes.
5 min agot I was playing YouTube music with no issues, made a phone call, then back to YouTube and now the bottom speaker quit and the top speaker is very quiet.
Any ideas on what could have cause my issues and can someone direct me to where Ii can find more information or what I'm doing wrong on on flashing new roms?
Currently running Android 7.1.1 build NGI77B

I've honestly encountered this problem a couple times but rebooting/flashing fixed the problems. Worst case scenario go back latest Google ROM with WUG's software, then you can install TWRP, then a custom ROM like Nitrogen ROM.
Sent from my shamu using XDA Labs
I know nothing about what anyone is saying, but I would like to add that using Viper4Android, and using "eXtra loud" at "Moderate" with the max gain at 4x and the max output at 0db completely gets rid of the low volume problem. Viper works system wide so it fixes it for Netflix, etc
Hope this helps guys

Sorry for the late reply, I had to put the Nexus 6 on hold due to another issue with it. I tried your kernel with the latest official version of Dirty Unicorns, but unfortunately it does not boot. It will boot fine without flashing the kernel.

Having this same issue using the NitrogenOS Pie rom. Updated from 7.1.1 (didn't have this issue with 7.1.1).
Is it better with the Oreo 8.1?

No . I can confirm that all oreo roms got the same bug .
For me am using android x unofficial pie rom with popcorn kernel. This combination seems to fix this bug !
Try them or even try the kernel with nitrogen os rom .It may work..

Unfortunately no. Mine WAS working perfectly. The charge port broke after about two weeks after I made this thread (my luck), and after having it repaired, the problem seems to have gotten worse. For one, it no longer works in the configuration I mentioned in this thread (mind you, I did not reset it or anything). It also now varies from rom to rom, with the bigger issue now being that the top speaker ceases to function on certain roms, including the way I had it. Now, it drops volume for everything, and most of the time the top speaker will be weaker for the slight moments both decide to work.
New problem
Hi Crossvxm. I have had a Nexus 6 for two years. When I wiped it to sell it, the audio problem started. I had PureNexus.
I did what you suggested. I turned on mpdecision with BlackBird kernel and kernel auditor. I installed su terminal, to execute these commands with root access:
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0034/force_calib
echo 1 > /sys/bus/i2c/drivers/tfa9890/8-0035/force_calib
And the full volume audio came back! Videos, youtube, all working again! But, the audio in calls worked no more. So, after that, I wiped all, installed PureNexus 7.1, Nitrogen 8.1, stock 7.1... I tried everything, but the audio in calls never returned. When I reinstalled all these roms, the low volume problem appeared again, but the audio in calls never came back. Even WhatsApp calls have no audio. The microphone still works, because the other person indeed can hear you.
Do you have an idea about how can I solve it? At least to leave it usable as phone. Thank you very much for sharing your knowledge and time.

This sounds like what happened to me recently. The configuration I mentioned in the very first post worked perfectly. After taking it to have the charge port fixed, the top speaker stopped working, and you could not hear the top speaker at all during calls. I thought the store broke it, but after giving up using it for some time, I realized that it would randomly try to output sound from the top speaker. After starting all over (flashing back to stock and flashing my same configuration again), the problem changed to where the top speaker was very low in sound when both speakers felt like working. I flashed the latest Dirty Unicorns based on 8.1 along with Popcorn Kernel by athulele but unfortunately it did not boot (as mentioned in his thread, the kernel is Lineage based).
I gave up on the Nexus for a few more days. When I decided to give it another go, I flashed the latest LineageOS (along with root for it via their own separate flashable zip), flashed Popcorn Kernel, installed Kernel Adiutor from Google Play (yes, it's spelled that way), installed the Terminal Emulator for Android and ran the command as well as checking the kernel settings to ensure MP Decision was on, capping the max frequency to 2.4Ghz (feels much less hot) and making sure everything was set to "set on boot". Unfortunately it did not work. The only way I got it to work again was to give up again, flash back to stock and flash Lineage and Popcorn Kernel exactly as I explained in this second paragraph.
So why did it work this time around? Everything was done the same, what could possibly make it work? I have a theory. When it was taken to the shop for repair, the battery died since it was already at 20%. As you can see I mentioned a few times "I gave up" on it, meaning I stopped bothering to fix it, and eventually it would run out of battery mainly from wifi and notifications. Every time it was dead, it was usually dead for at least 24 hours. Each time around, the issue would change. I don't know what it has to do with anything, but I do believe it plays a key role. Try letting your battery die, charge it back up to 100% and then try the process from either paragraph two or from my original post. After it began working again, I abused the heck out of the speakers, rebooted the phone, tried calls, etc. all without letting the battery die and it has not stopped working. I recently sold it as is and was contacted by the person who purchased it who was confused as he did not experience any sound drops either. He was originally buying it to replace the screen on his but decided to stick with mine since it was working perfectly so far.
1. Background
It's been 4 months since I bought Xiaomi K20 8G and 256G(Not Pro). I bought it from China, and from the beginning, the cell phone was unlocked. (I didn't know what it was. Maybe the seller changed the Chinese version to Global Rom and sold it. I didn't even know what that meant at the time. I think seller stated the same.)
2. Problem
There was a bit of heat from the beginning. And I got many messages that due to heat warning, the Wifi, camera, and 3G/4G would be limited. In relation to that, I found out that there had been a lot of such problems while searching solution in Internet, and I saw many articles, software upgrades had solved such overheating. And someone recommend such thing can be solved by installing ROM again in the setup(there is menu downloading latest ROM). So I tried this (MIUI 11.0.4 global) and further deleted many apps and re-installed apps, used battery saver mode and etc.. Though there was heat, phone didn't give a overheating message, and wifi also worked well.
For the time being around 1 month, I used it well.
Just 4~5 days ago, again overheating message came. Then new ROM (11.0.5) came and phone got hang / shut down / reboot / Overheaing warning / wifi disconnected.(WIFI is on, but suddenly not working. Then I off WIFI, tried to on WIFI but it didn't ON. Toggle button move but come back off position again, Once I reboot, it work for some time only.)
3. Attempts to resolve
Although phone has heat, I decided to install TWRP & the other operating system (ROM) because I thought such problem coming from the operating system / software / apps rather than a hardware problem.
I've been working hard on installation of Pixel Experience following the guide of the experts, but the above problems persist, I've changed Global Rom to EU Rom, I've tried downgrading from the recently updated MUIU.
However reboots occur more and more frequently.
Even though I don't do anything, my K20/9T phone is rebooting, hanging, stopping, and shutting down. And even no tasks are there, heat is on the phone.
