nexus 4 randomally shuts off? - Nexus 4 Q&A, Help & Troubleshooting

have an old nexus 4 i wanted to try fixing a few issues with so i could keep using it as a backup phone.
It likes to sometimes not wake up from stand by. i'll go to use it and the screen won't wake up and it is hard to get to reboot but eventually does then works fine for a bit then repeat. Sometimes even when the battery is fully charged i could go to sleep one night wake up in the morning and it's like it just randomally shut down and is sometimes hard to start other times not, but always has to fresh boot.
not sure what the issue is.
i have re flashed OEM roms in the past to try and fix the issue, and ofc it just updates to 5.1.1
>< all help appreciated.

probably battery issue

It's probably battery. Does the phone shut down on charge?

I have same issue and I don't think that it's something wrong with the battery, because I already changed the battery and nexus 4 still freezes sometimes. And it's looks like freeze, not regular shuted down phone, because it's hard to wake up after that happens.
I read somewhere that this may be issue with internal memory, but I'm not sure about it.

Had same issue running on stock 5.1.1 or something like this. Shut downs, reboot, frozen screen, donĀ“t wake up, start problems, networking complete breakdowns.......installed Lineage 15.1 official and no such issues so far.
So it might be Android related.
So best thing, unlock bootloader by Nexustoolkit, flash latest custom recovery TWRP (you have to flash an older version first, if not having TWRP allready) and then install Lineage 15.1 official. Use instructions provided by XDA. It might be dropped, but it runs great.

Phone randomly stops sleeping

My phone will randomly stop sleeping, this has happened pretty much since i've gotten it.
I will launch spare parts, running near 100%. Check partial wake lock, nope nothing. And nothing under any of the other menus in spare parts that would indicate it not sleeping. This will occur after a couple of days even after installing no apps, restarting does not fix, neither does pulling battery. It will just start happening and only way to fix is data reset / factory wipe until it happens again, but when it does start happening I might've not even be using it at the time.
Okay, i did actually finally fix it after months without factory reset, it appeared to be when 3g and Data-always enabled was ticked.

If this fixes my no sleep problem, I will name my first child after you.
I've been detailing the steps I've taken to resolve my no sleep issue on another forum, with the last action I took being a flash to factory ROM from huaweidevice.com, changing absolutely nothing on the phone for 24 hours, rebooting, and waiting another 24 hours. Without a reboot between charge/taking off charge, it would be 100% running. If I took it off charge and immediately rebooted, running would be more like 30% (ie: 'normal').
I'll give 'data-always' a go

Wooh, nah for example my running time is 8.7% and screen on is 6.1% so that is pretty good, thats over the course of about an hour

Okay im unsure now, was all fine yesterday, woke up at 7 to alarm, lost 2% overnight. then just put it under my bed but now that i've woken up i've lost 18% because it just stopped sleeping again. I didn't do anything except turn it on check battery, and turn it off. So back to being confused again
Still having this problem, for example. It was sleeping fine when I went to bed then at some point during the night just stopped.
Running 64.6% 10h
Screen on 10ish% 45 minutes
Highest item with partial wake lock in spare parts is like 5 minutes, no other indicators.
This is happening no matter which ROM i try.
Considering a stock ROM with exactly 0 changes still has sleep issues, its clearly a firmware "thing".
For me, it happens after being taken off charge.
For e.g. Last thing before bed I check my running time, and its somewhere around 35-40%. Plug into charger. Take off in the morning, goto work etc, check my run time and its 100% even without the phone being touched.
For the moment I just downloaded one of the "root only" reboot widgets from the Market. Its just part of my morning "get ready for work" routine to hit the reboot widget and reboot my phone.
Its a bit of a PITA but until new firmware is released I cant see a way around it.

Hey don't know if you've tested it further than that. But its much appreciated, that rebooting after charging does seem to work . But just wondering, if you know... does it only do it when charging via usb (computer) or AC or does it not matter?
I have exactly the same problem.
I also noticed that reboot helps, but only for a while. If i want my phone to go to sleep mode when the screen is off, i would have to reboot it few times a day... Turning WiFi/GPS/Auto-sync on/off does not have any affect on this.

As per your suggestion via email, I tried the Malaysian firmware.... It seemed that 'running' time was down alot, but battery life was still pretty average. That was doing nothing more than installing the Malaysian firmware and entering my Google account - no root, no launcher changes, etc.
The lack of Swype was a bit of a downer too
I gave it a whirl from 6:30am to around 5:00pm and 'running' was right down in the 10% range, but battery was still down to ~45% over that time in 'pure' stock form. DAMMIT!
Ah well. It was a good thought and hopefully it worked for you I'm back on roadhound + the OTA update as of about two hours ago.
I'm going to scour the SGS forums and see if anything there can be applied to the U8800 RE: battery life improvements.

Oh yeah sorry, try using something like juice defender to disable 3g when screen is off or something. 3g radio keeps it running, but it doesn't appear to be, this will stop the battery drains.
EDIT: That does work but its not ideal, turns out the u8800 and the u8800h use the exact same radio so im not sure now, don't know if there is any possible way to figure it out.

Sometimes i have 3g data connection running, but phone goes into the sleep mode when screen if turned off. So this is not the cause.

Oh no, this is just the case for the U8800H malaysian firmware seems normal for all U8800 firmware.
I'm not using u8800H firmware and i have this bug.
Hey guys.
This may not really be the thing you need but I was having similar problems and running 100% on without sleeping etc and came accross another forum where this was an issue (cant remember where)and as trivial as it sounds the solution for me was to go into settings/ applications/ manage applications and running applications and go down to media storage and clear the data. I do this now and then when I have this problem and it seems to help.... Maybe worth a try? It seems to be an issue with a particular media file. I also try to reboot my phone after every charge. Note that my phone is totally stock

Thanks for advice, but unfortunately this didn't help either. For some unknown reason, my running time is again 100% although the screen is off most of the time. In Partial wake usage, Android System is in the top of the list.
Oh, Android System partial wake lock seems to be a different issue, but maybe someone can help you out. Whats happening here is running = 100% yet there is no partial wake lock held. Quite unusual

Yes, it is confusing also because i have tried different ROM's with same result. I would have thought that all u8800 owners have the same problem.
same problem here...

Phone keeps turning off! Never while using it & sometimes when phone is not moving.

Phone keeps turning off! Never while using it & sometimes when phone is not moving.
I have an LG-D801 running 4.4.2 kernal 3.4.0 and software D80120a. I also have and use TWRP for recovery. Ever since I rooted my phone and installed this rom, everything has been perfect! That was about 4 months ago. I have and use lots of apps, most of which I have been using for years without any issues. Lately I have been finding my phone off in my pocket for some reason. It now is happening maybe 6-10 times a day which is really getting annoying.
The LG G2 battery doesn't come out so not like it got loose. I have tested it by sitting on the desk lightly and checking it later to STILL find it turned off. So I know I'm not bumping it. I have tried an app killer to kill apps before turning off the screen but it still seems to happen. The phone is still relatively new so I doubt it's hardware, I baby my phones.
Any ideas for ways to make it STAY on without flashing a new rom? Or maybe ideas for how to diagnose what is shutting it down?
(I am looking for ideas and useable feedback, please don't respond that my phone has hardware issues and needs to be replaced!)

Are you sure it's actually off and not just asleep and not waking up. I've never seen a generally working phone turn itself off. On another device we called it the SOD (Sleep of Death) and required a long press on the power to reboot. It's most likely a rooted app like something Xposed related perhaps.

How can I tell the difference? Basically I press the power button once quickly to turn the screen on and it doesn't come on. I hold it for maybe 3 seconds and get the booting up stuff. I am guessing if it was sleeping I'd have to hold it much longer?

Yeah bud, that's a new one on me. Do you have any root apps that could be the cause? Like Xposed.

Thanks for the help. After reading your previous post, I decided to remove GravityBox KK and Xposed. I was using it because I find it annoying that when I plug in my phone at night, it turns on my screen. Not a big deal...
I also use SuperSU and LuckyPatcher which both use root. The only other thing I can think of is that I semi-recently upgraded my Play Store (v4.8.19 using Lucky Patcher) which I had some troubles with. It kept saying my /system was out of space and for some reason, even with root, it tells me acces denied when changing stuff inside the /system such as boot animation.
so... just an update. It's still doing it even after I uninstalled all the apps that need root. I really wish there was a log or something (like Windows) to tell me why it keeps turning off!
I have noticed it seems to happen much more often if I am texting somebody even though I'm using the default app for messages. It literally was turning off after every message I sent early before the other person was able to reply for about 5 messages in a row.

Note 4 freezes while charging after lollipop

I tried posting this in the Sprint thread but haven't gotten any answers yet so perhaps I'll have better luck here. I pasted both posts to show the initial problem and what I did (essentially I factory reset). I'm still having the same problem where my phone will freeze while I'm charging it (about 2-3 times/week) requiring a battery pull. Anybody else seeing this problem or have suggestions on what I should try? Thanks.
-----------------------------------------------------------------
Twice this week my alarm didn't go off (luckily I set a backup today) because sometime throughout the night something happened. When I woke up the phone was frozen on the yellow Sprint Spark startup screen. I needed to pull the battery and everything started up fine. I updated to Lollipop about 2 weeks ago which is where I'm guessing the issues stem from.
Is there anything I should try other than restoring to factory and starting over? I'd prefer to not have to wipe everything from my phone but these issues are becoming problematic. I am not rooted.
Thanks.
--------------------------------------------------------------------
So I ended up doing a factory reset and while the phone certainly started running faster with better battery performance after the reset I'm still having this issue. I would say it occurs 2-3 times a week. It has only occurred overnight which is typically when I charge my phone so I'm pretty sure it is related to being left connected to the charger. The majority of the times I will wake up with a dim yellow Sprint screen and everything else frozen though occasionally the screen will be black with the led notification light red. In both situations the screen will not respond to any button pushes or holds and I need to pull the battery and then everything will start up fine.
Does anybody have any suggestions here on what I should do? I guess I can try and restore one more time and see but I don't really know why it would be different and it is certainly a pain to keep restoring the phone and losing all my settings. I definitely don't want to root now since I believe that voids the warranty and if I can't figure anything out with this I'll certainly be requesting a new phone from Sprint. Before I start dealing with Sprint though I thought I would check here first. Through all my searches on the internet I haven't seen anyone else complaining about this problem.
Thanks.

Hi there. I have a Canadian Note 4 (W8) with Bell, and I am having identical issues.
While charging over night, I find my phone stuck on "Samsung" logo, with the bubble animal still running. Holding down the power button does nothing and the only work around is the battery pull. I noticed that it also gets warm (assuming from the screen on time?)
First tried cache wipe - no fix
Factory reset - no fix
Cache wipe again - no fix
Aaaand today I came into work late

Did your issues first start after you upgraded to lollipop?

Definitely after the upgrade.
While on KitKat, it never happened (1 month ownership). But after upgrading to lollipop, it has happened 4 times (6 nights since lollipop).
Have you figured anything out with your situation? Woke up this morning to my backup alarm and the Yellow Sprint screen on my phone.
I guess I'll have to try another factory reset and if it still happens try and get a replacement. It just doesn't seem widespread enough of an issue to be a software bug with 5.0.1.
Very frustrated. I did another factory reset but the issue still plagues my device. It still only occurs once or twice a week but when I hear my old clock radio alarm in the morning I know when I look over I'll see the yellow frozen Sprint Spark screen. I am completely out of ideas and guess I will need to have it replaced under warranty. I'm hoping Sprint won't give me a hard time as this will be very hard to demonstrate.
It definitely appears to be a software issue as it never happened before I upgraded to Lollipop but there must be more to it or others would be complaining.
If anybody has ideas please let me know. Thanks.
Response to Note 4 Freeezing while charging
I have found that after turning the quick charge feature off the problem is not happening. Hopefully this is fixed in 5.1
I'm having the same issue even after turning quick charge off..def a lollipop bug, never experienced this on kk.
I know its not the BEST option, but after taking the update to lollipop, sometimes left over kitkat files can make the system poop out. Sometimes a factory reset will take care of the leftovers. But of course, then you have to set your phone up again
If you've tried this or plan to to, let us know the results.
(When i first took the update, my heartrate monitor sensor was always on, so i did a factory reset and it fixed my problem).
Solved with workaround!!!
I faced this "sleep of death" too after updating to Lollipop. I had to pull out the battery almost every time after charging. Very annoying! I noticed though that my phone never froze in my car while charging. Thinking about the difference I realised that I keep my phone awake in the car while charging using Macrodroid (which I love anyway to automise all kinds of things). I made a simple macro which keeps my phone awake while charging and another one that returns the phone to normal while on battery.
While charging: Trigger: Power Connected; Actions: Keep Device Awake enabled & Screen Off, Constraints: None
On Battery: Trigger: Power Disconnected; Actions: Keep Device Awake disabled & Screen Off, Constraints: None
Off course there are alternatives available to Macrodroid that should be able to do the same.
My problems are solved, with and without fast charging. I hope this will help some of you as well.
same problem here
Ive tried turning off fast charging option on the powersaving mode
And also tried the option on developer mode, the "keep device awake while charging"
And even flashing dofferent firmwares from sammobile through ODIN and installed custom roms. These options doesnt resolve the issues on freezing while charging..
I think turnong off your device while charging is the only option..
Im using note4 N910C..

Thanks a lot, Mate. I'm trying your workaround now. Will report later if it works on my phone. BTW, so, are you sure it is a just a system issue? Definitely, isn't a hardware problem? Did you fix it, after your post -a month ago-, installing, for example, lollipop 5.1.1 or Cyanogenmod 12.1? I'm on 5.0.1, SimpleRom V4. Of course, mi device, N910C, is rooted.
Thanks again.
With lollipop 5.1.1 the problem is solved for me, even without this workaround.

I'm having similar issues as you guys. I found out that my phone will only perform normally when I charge it with my laptop USB port which I think is around 0.5amps. Anything above that, even a 1amp charger would cause the phone to freeze, reboot and turn off and not turn back on. The phone has been in repair 4 times and the problem is still there. Now every night I'm forced to charge my phone with my laptop which takes an age instead of the fast charger that came out of the box.
Currently my phone is still freezing and rebooting when I'm out and about and the only way I can get it to perform normally is when I plug it into my laptop. This normal functioning would only last whilst the phone is plugged in.

Random shut down

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

Note 4 (T-Mobile) Lag, Freeze, Crashes, Restarts.

This is my first post on this forum. I searched around here for a solution, didn't really find one matching my problem. I am not a phone wizard or anything like that either. So I'll try my best explaining my problem.
First things first:
Phone: Note 4
Model #: SM-N910T
Android Version: 5.1.1
Rom: Stock Rom
Rooted: Rooted Once and used a custom Stock T Mobile Rom Once.
Here's the ROM I used at the time: http://forum.xda-developers.com/not...10tuvu1cog2-debloated-deodexed-stock-t3175406
Recently I So recently my phone out of the blue started lagging, freezing, and restarting itself. I didn't download any applications or anything like that for it to freeze up. I was currently then on the custom ROM I have mentioned above and it was the updated version. I have tried everything to my knowledge to try and fix the problem. I have tried going back to stock T mobile ROM (currently on stock rom now) through odin and stuff. After all that, it was still lagging, freezing, and restarting etc... Ran it through safe mode and the only problem in safe mode is that the lag is gone, but the restart is still there. Running in safe mode, if I would turn the screen off and back on to unlock my phone, there would be like 40% chance that it would restart after unlocking the phone and the phone would just restart normally. Rarely, whenever my phone would attempt to restart.. I would get a "Could not boot normally" message along with couples codes below and the image of android guy. Then I would have to take my battery out and attempt to restart the phone once again.. I've wiped the cache and everything in recovery mode, nothing helps at all. Also, the phone is in perfect condition. Hasn't been dropped, cracked, no water damage, or anything like that.
This place is my only hope to fix my phone before I will go out to buy another phone from the carrier.
Thank you all for taking your time to help me

Well I already got rid of my note 4 unfortunately before anyone could help me here so I had to upgrade my phone to note 5 and return note 4. While I still had my note 4, I realized something weird. While the phone was lagging and crashing etc.. When I had it plugged in for charge it would work perfectly fine. No lag, it wouldn't freeze up or restart (had it running perfect for 7 hours). It was like my phone was brand new again. As soon as I unplugged it from the charger, few minutes in and it was back to restarting and all that. I never knew why it did that.
Anyone know why this mightve happened?
Might be the battery though
I thought that too. I tried my brothers note 4 battery for awhile and it worked for a little bit and then it started doing the same thing even on his battery. Shrugs.

In the COH update iteration there is an annoying bug that affect fingerprint.
The bug causing the phone to restart, lagging & closing all apps randomly when the fingerprint is set.
May be this one is also the same.
Try to disable all fingerprint related settings.

I never used finger print scanning on my Note 4. Always disabled.
