Hello lads! The last few days I have been trying to fix a huge problem with my Galaxy S4 i9505. I had been using the Google 4.4 rom for almost a month without any problem. One day, when my phone was low on battery it shutted down and I plugged it in my charger to power it on again. When it turned on I was prompted to the screen you see when you use the 4.4 rom for the first time. I had all my apps but everything was resetted. Every setting, all the app data, messages, etc. I thought this was a one time thing so I used about an hour to get everything back to normal again. Then the next day, same happened again. Phone turned off because of low battery, and everything was reset. I tried to google it but with no luck, so I did a factory reset and flashed the newest Google rom (4.4.2) with a new kernel called Ktoonsez. Got everything back to normal again and used my phone for a couple of hours before it just suddenly shutted down once again, but this time with almost full battery. When i tried to turn it on I was stuck on the Google loading animation and had to reflash 4.4.2. It turned back on and this time I decided to let the phone stay stock to see if any of my problems was caused of my apps or settings. It lasted for 2-3 days before the same thing happened again... I tried to flash different modems, other roms and firmwares but nothing have helped so far. I am also prompted with a message each time I turn the phone on which tells me that com.android.phone has stopped working. I have tried several factory resets, wiped dalvik, wiped cache, but still has the same problem... I have now given up trying and wonder if anyone of you know what I can do to fix the problem? Any tip is much appreciated and I hope to hear from you! Thanks!

So I got my Note 4 (N910F) a couple of weeks ago, everything was fine until today when I changed the sim cards, now the phone randomly restarts. I have taken the micro SD card out, that seemed to increase the time between restarts slightly but it still happens, also checked to see if the battery was inserted properly but that was fine. Is there anything I can try before doing a factory reset? Would be a considerable chore to download/customise everything again with no guarantee of it fixing the problem.

same problem. but after factory reset. i haven't encounter any random restart
Just a bit of an update, found out that the problem was with the CPU power saving feature. Turning it off prevented the restarts from happening, just tried to enable it and got a restart. Would recommend anyone getting this to try disabling CPU power saving if they haven't already, before trying a factory reset.
Why CPU power waving causing restart when enabled?
Today I picked up my phone up to send a text and it was no longer powered up. It had randomly shut down.
When I switched it on again I noticed it has lost its battery stats so looks like they were reset or lost. There were no user apps installed on the phone either.
Have you had a similar experience?
You could try to reset it or take it back. Could be defective!!!
Was it somewhere it was hot? Maybe the phone got too warm and hit the shutdown temp?
Honestly hard (read impossible) to tell you what happened. Have any more info / logs?
I haven't had any issues with heat or shutdowns at all. I get 6+ hours SoT every single day at 75% brightness. 100% stock and unrooted. I use my N5 for all the modding aspects like V4A, Xposed, etc. I want this one for Android pay.
Anyways my uptime has been running since I unboxed it on 11/9/15. No issues.
I actually had it reboot in my pocket yesterday on the first day i had it but I already installed a custom ROM so no testing it out now.

It was only room temperature. Here in England at 18cc so not too hot, but good point.
I read about the same thing happening with a N5 and it turned out to be a defective mother board.
Guess I should return today then... Bummer
If you just got it, might want to see if it happens again. I had one random reboot the first day and its been fine since.
My phone has started doing the same thing. Twice in 3 hours.
Same here...... 3 times reboot..... And now 2 times shutdowns.
I started having random reboots after I installed greenify. I tried several settings but had the same problem. It rebooted 5 or 6 times a day. I uninstalled it and haven't had any more problems.
I had my phone shut off yesterday and wouldn't boot until I plugged it in (it was at 80% battery). I then noticed that once it booted, it had deleted all of my paired Bluetooth devices.

Was just having the same problem but it was happening every 30 seconds to a few minutes. Deactivated greenify's device admin ability and now it's gone. Hopefully it stays that way, though if it comes to uninstalling it, that's fine since there don't seem to be as many background apps running on the 6P compared to my verizon LG G4.
Nevermind had to uninstall it.
Shut down, and a little warm
My nexus 6p shut down nearly every day, I just picked it up and it was shut down, I looked under battery and I could see it has been shut down for hours.. hope somebody knows anything about this problem.. I don't think a hard reset will help, because when I got the phone I installed all the update to Android 6.01 (MMB29M) and then I did a hard reset to make sure the phone was as good as it could be..
But maybe I'll try one more hard reset, just to be 110% sure

I'm having this problem too. It happens a couple times a day, and I think it always happens right after I pull it out of my pocket and try to unlock it. I'll feel the vibration from the Nexus Imprint fingerprint sensor, but then the screen doesn't turn on. So I try the power button, and nothing happens because the device is suddenly off. So then I hold down the power button to turn it on, and it boots normally.
Someone mentioned this happening with stock software, which makes me think it's a hardware problem, so we'll need replacement devices. However, I do have Xposed and GravityBox installed, so I need to rule those out first by removing them for a while.
I've had the phone for two weeks now and so far this happened twice.
The only two things that come to mind:
- enabling SRGB in the dev settings
- using a bluetooth headset
Has anybody pinpointed whether this is a HW or SW issue!?
How common is this ... I've seen ppl complaining in this thread and in Reddit also on random reboots as well
Thx
Still happening...
I am having the same issue. Did the reset to factory with no help. Phone was not hot, was sitting on my desk with 81% charged battery. This is the 3rd or 4th time in a week it just shuts itself off for no reason. Has anyone found anything??
I'm having this problem too, now on DVP 3 it's even worse. But I notice today that alarm clock works, but the screen won't. So I think is a SW related, the screen won't wake up, and after a while if you press the buttons the phone reboots. Anyone have e ideas how to fix this?

facing this problem since may security update, on purenexus , dirty unicorn and rr rom. dont know if it hw or sw or simply power button getting pressed accidently.
I think I need to reopen this post, coz' I've been facing thif problems for so many times this week so I google around and come to this post.
Has anyone come to a workaround or point out if it is software or hardware related yet...? If it's hardware then I think I'm gonna go for a replacement then!!!
If you haven't done so already, go vote in the "early shutdown" poll
Hey guys,
last week I've started having some serious issues with my phone. I wouldn't say it lags, it freezes for 10 to 15 seconds at a time and then it's smooth and fast again but it does it every minute or so and it also freezes with screen turned off, so I have to remove battery almost every time. First I thought that some app may be doing it so I did factory reset but it didn't help. Even though I was on stock I thought I would try some custom ROM to fix the lag but after flashing... the same story, so I reverted it back to stock. Only solution I've managed to find was to remove simcard and sd card but it didn't work for me either. Any idea how to fix it or do you think, that it's hardware problem? I have SM-N910F with android 6.0.1
So, here is my problem. I've got an almost four years old Note4. I flashed some custom ROM's after i bought it but then I found an old X-note 4.4.4 based custom ROM and i was using that for more than 2 years. Yesterday around noon i noticed that if I try to use Viber, it takes seconds till it opens, and lags badly. (Before that the phone was working perfectly for years). I deleted it, reinstalled, but the problem stayed the same. After a few hours all the other apps started to do the same, the phone became really laggy. As time went by it got worse and worse, around 8pm it started to freeze, reboot, became almost completely useless. I thought maybe a factory reset and a new flash would help. I did a factory reset, and flashed a completely stock ROM on it. It started well, was working good for an hour or so, and then the same problems occured again. Lag, freeze, reboot.... And then nothing. Did not even restart. I can switch it on every now and then, (like in every 20 minutes), but it boots into odin mode. I thought maybe the battery, but that is less then 2 months old. Anyone any idea what happened? I mean the phone is almost 4 years old, so I'm not really pissed off, the only reason why I wanna keep using the Note4 cuz it's removable battery. I don't like phones with built-in battery, this is why i did not upgrade to Note8 for instance. Any help would be much appreciated. By the way, my device is an SM-N910F.
Well, things got even weirder later. I found my old battery which i replaced 2 months ago, still had some juice in it, i put it in, and the phone started!!! Worked perfectly, for about an hour and a bit, then the same problems occured again, lag freeze reboot, and now it boots itself into recovery if i can start it up at all... All the same story. Anyway, i threw it in the drawer and bought a new phone.
