Nexus 7 keeps turning off at random intervals - Nexus 7 Q&A, Help & Troubleshooting

This has been going on for about a week or so.
At first I kept finding it off in the morning after charging, and then it became more common. Mostly happens when the screen is off but not always, I've had it turn off twice whilst I'm using it for example. A couple of times it has needed a long press to restart it before it will turn back on. Right now it has turned itself off and will not turn back on.
Battery has never fallen below about 50% throughout so it cant be that. It doesn't get heavy use so I'm not convinced its overheating. I had a look through the app list and none of them seem to be obvious candidates for the problem, and if i cant get the thing to turn back on I cant even test that.
I think this one is going back to HMV asap but I was wondering if anyone has any ideas for me to avoid the problem with its replacement, or if anyone is having the same problem. Its a shame as I've been really enjoying my Nexus.

Hi, I had the exact same problem and ordered a replacement from the play store. I never found a way to fix it, I would recommend you just get a new one from HMV. I hope this helps

This actually just started happening to me yesterday on my 3 day old 16GB Nexus 7. I kept mine plugged into the AC all weekend, and yesterday watched it shut down itself once. Thought it was a fluke and just turned it back on...left it running overnight...pick it up this morning and it's turned itself off yet again. I guess I'll have to return this one before it completely doesn't turn on anymore!

Bah. Thought that might be the case.
2 days off charge (and some time on charge) and mine still wont turn on.
Definitely going back for replacement.
Elsydeon, it sounds like you should do the same. Took about 4 or 5 days to go from irregular to brick.

I seem to be getting the same thing... Once every day or two I pick up my Nexus and the screen won't turn on, I hold the power button and it starts booting up. I haven't had this while charging (maybe because the screen is on while charging??)
For those of you who traded in for a replacement, did this solve the issue for you?

I was getting this, but was using one of those magnetic cover/cases. If I wrap the cover round the back of the N7 whilst using it, the magnet in the case/cover is sometimes strong enough to turn the device off from the back!

Mine has powered off twice now

Just wondering as well like the last guy if swapping for a new one helped this issue.
I actually have looked at the battery data and think somewhere the nexus has gotten a power spike that turns it off but not sure if that definitely is the issue.
If it is, perhaps it's where we are plugging in or a failure with the AC plug?
Ideas? I've attached a photo. I hope it uploaded.
Thanks.

Me too
unless i hear different from anyone here, going to exchange it for a new one today ... only been 2 weeks from Staples.
Actually going through the data, it's happend the last 3 days now.
I wake up to the white battery symbol.
By the way, for future ref, is bootloading warranty killing? I am in the process or restoring now just in case.
Thinking of getting their replacement plan now too because of this episode.
Thank goodness for titanium backup

Nexus 7 32GB Display Keep Turning Off
My Nexus 7 32GB tablet's display continues to turn off at random times also. It happens while I'm watching a video in landscape. But then I stop the video, go to the home screen, and it still turns off. I already replaced one last week and now its happening to my new one. Anyone got answers? I'm going to call google device support today. Maybe if enough people call, they'll do something about it. Their # is 888-836-3987.

Still happens

My NEW 32 tab worked out fine for a night and woke up today to the full battery indicator and tablet off again.
I have a new insight though, somehow the battery temp is rocketing to 100 and I'm guessing that is when it shuts off.
It may be because I am using SetCPU to limit my CPU speed to 300mhz when the screen is off. Maybe the tablet is trying to update all my apps while I am sleeping? It shouldn't use so much power though.
I'm going to try to create a new command to let it use it's whole CPU as long as it's on AC and screen off and see what happens tonight.

Happened overnight again. No insights? Does anyone think my nexus will finally brick sometime?
I don't know anyway of testing what is up with this thing? Thanks.

Nexus 7 Screen Keeps shutting off - Fixed
To those experiencing issues with their Nexus 7 screen randomly shutting off.
I just received one for Christmas, and thought this dang thing sucks. The screen would stay off and only show for half a second when I click the lock button to turn it back on.
The issue what the case. The the case, when folding back, contains a small piece of metal on the click. This little connection, thought not direct, causes the screen to shut off. I've tested it out multiple times just to make sure.
Again the FIX is, keep metal away from the back of the nexus, it doesn't like anything that can cause a magnetic field. Even if the metal is enclosed by something.

nexus 7 screen turns off
For those of you who are experiencing intermittent screen display going to sleep mode or turning off you can fix it by removing your tablet cover. Some third party tablets come with different strength magnets stitched inside the cover. The magnet is used to activate the nexus tablet smart cover functionality. If you flip the cover to the back of the tablet the magnetic field may cause the tablet to think it should turn off while in use. Get rid of your cover reboot your tablet and notice that the screen will stop turning off. Hope this helps.

Hi, I also had similar problems with my Nexus 7. After removing the back of the unit, I saw that the battery was nearly unplugged. I simply popped the connector in and voila! no more SOD, turning off, nothing.
So, the Nexus was probably turning itself off because there was randomly no more power comming from the battery.
Here's a link on how to remove the back shell : http://www.ifixit.com/Teardown/Nexus+7+Teardown/9623/1
Look at Step 4.

That Fixed It!

I was researching before going to get my Nexus 7 replaced today as it also started having this issue. After reading your post, I took your advice and removed the back to find that my battery connection was also barely intact! Thus it would lose power any time it was bumped slightly to that side. Now that the connection is securely in place, I've had no more problems!! Thanks to you StefGou!!!

Hey guys. A few hours ago I encountered the same said problem. I woke up to find the battery was depleted so I charged it. It turned on by itself and stated that I have 6% battery left. As I wait, suddenly the screen was like distorted and give me static sound then shut off. Numerous trials later end up the same. So I just put on the charger thinking to let the battery full. To my surprise, there was no indicator that my N7 is charging. I just leave it charging and left. About an hour I got back it still nit charging. I boot the N7 and it still on 6% battery. So I followed you guys handsomely instructions to remove the 3rd party cover and now my N7 is back. Thanks guys. But I wonder why it is happening now? I've been using the cover since forever.

[Q] Help with DVP - won't turn on

Hello. I created this account so I can finally ask some of my questions regarding this phone. I've had it since the January 6th shipping, and it's really been fine for the most part. I've the 8 gig version.
Anyway - within the last few weeks my phone has been refusing to charge on random occasions (it's really very random as to when it will charge and when it won't) - both plugged into the wall outlet via the USB power converter that came with my phone and plugged into my computer.
It's been pretty annoying, but nothing I couldn't work around. It would charge eventually.
However, last night I plugged it in to the outlet and it made the noise confirming it was plugged and started charging. This morning, I unplug it and it's non-responsive. It doesn't respond to anything. I have tried:
-turning it on with the power button; holding it down for an extended period and releasing
-taking out the battery
-plugging it in to my computer (which didn't recognize anything being plugged in)
-plugging it in to a different outlet with a different cable (phone came with two)
I've let it sit plugged in for three hours now and retried all of these things and still nothing... it's dead!
I'm not sure where to go from here? I guess I should have my husband call Dell.
Has anyone had any trouble with the sporadic charging?
Are there any solutions I've missed to get my phone to turn on?
You say you've let it sit for a while, was that plugged into a power source? Try that, it sounds like your battery has gone completely flat and probably needs to sit on a power source. Failing that definitely call Dell and get a replacement battery and charger and see if that fixes it, sounds like one of those items is your problem.

Yes, it has been (and still is) plugged in that whole time. I edited my post
Yeah, something is wonky, I just cannot pinpoint it. My husband's will sometimes not charge, too. But, much less often than mine does.
charging issues
In the last 2 days my VP freezes while charging overnight. Restarts when I take out and replace battery. It will also freeze when I try to use any app while charging. I tried to use Dell chat to resolve issue but got bounced around. I even had an agent tell me my service tag wasnt valid. I'll try to call 800# when I have a free hour or so (I'm sure the call will take that long). The first two levels of support at Dell seem to have no clue regarding the VP it's very frustrating. P.S. what happens with all the apps I've purchased if they need to replace my phone?

Have you swapped batteries with your other DVP? Maybe replacement is the only option, hit up @dellcares on twitter, they have helped me in the past and bypass the whole waiting on hold nonsense with dell mobility.
@tbvnz: all your purchased appls will be reinstalled automatically if you installed them via the Zune software on your pc. The ones installed via the phone can be reinstalled from the MP on the phone, just hit the Buy button again and it will tell you its already been purchased and allow you to download it again.
Update:
I snagged my husband's battery and put it in my phone. My phone immediately came on and is now functioning. My computer recognizes it as being plugged in and it's charging.
And, my battery in my husband's phone works fine. It is fully charged and his phone is having no issues.
Certainly this is annoying (and did in fact happen to my husband a few weeks ago where his phone wouldn't respond until MY battery was put in his phone, but we chocked that up to the battery being dead {which it was}.) but at least my husband and I both have DVPs and can interchange batteries... I wonder what someone who didn't have that option would do.
Certainly confusing that removing and replacing my existing battery wouldn't turn the phone on, but my husband's would - even though both batteries are at full charge.
Thanks for the help! I'm not sure if I should contact Dell about it or not. Clearly it's subpar performance, but I've not been completely impressed by this phone in the nearly two months that we've had them, anyway.
Good to hear you are up and running. You could keep an eye on the situation and contact Dell for a replacement battery if it occurs again.
Thanks. Yep, I'll contact them the next time it happens. Anyone else had this problem??

My brother and I have experienced the same behavior on both of our phones. Most recent was his this past week, exactly as you described. It would not turn on via the power button, so I swapped his battery with mine and his booted right up. When I tried his battery in my phone it showed a full charge. That has happened to me one or two times, randomly.

I've seen that behavior in my DVP (picked it up two weekends ago) and I can tell you how to work around it.
What seems to be happening is some kind of bug when you have it connected and charging and try to turn on/off the phone. If you notice, when it seems unresponsive, the hardware keyboard will probably still light up. This is because it's actually on but the screen just doesn't get any output/input.
What I did was this:
1. Disconnect your phone from the charger.
2. Slide the hardware keyboard down so you can see whether it is lit up (on) or not.
3. Hold down the power button until the exact moment you see the keyboard go dark (off). You have to be quick because it will try to turn right back on a few milliseconds later if you still have the power button depressed, leaving it still non-responsive.
4. Wait a few seconds, and press the power button as normal to turn it on. This time you should see the Dell logo, etc. and everything will be fine.
I've gotten into the habit of either leaving it on or turning it off before I connect it to my charger (it's my alarm clock so it's on almost all the time).
Hope that helps.
my DVP won't turn on either...
Hi - i'm glad i found this post because i've had my DVP for 3 days now and its frozen about 5 times and this morning wouldn't turn on or seem to take a charge. it was fully charged when i put it down last night and this morning there was nothing.
i've stuck it into a wall outlet for now and i guess i'll just wait for it. don't know what else to do. don't know anyone else around with the same phone, so that battery swap isn't an option. pretty funny that you realized to do that and that it worked.
anyway, i feel better now that i've complained about it. thanks.
Did you try pulling the battery and then booting it up? If that doesn't work, after a pull just leave the battery in the phone and let it charge. After 20 minutes you should see it power on.
So it's continued to happen with my phone whenever I have it plugged in to the wall with the brick that came with the phone. Annoying! Basically I cannot have it plugged in next to my bed; it can only charge on my computer. So much for using it as an alarm!
I will try the power down and reboot with the keyboard out. I know what you speak of with the flashing keyboard. I hadn't tried to see if mine is flashing while the phone is 'dead'.

I almost swore I wouldn't buy another Samsung!

Before I owned the Note, I owned a S2.
I was impressed by the fact that it is the smoothest Android phone on the planet at that time.
But one day, I was using my computer to do some stuff.
The phone was just beside me.
I noticed the phone's battery is going to kapoot.
I even seen it going to sleep.
Too busy, I didn't notice the phone actually died.
When I was about to use my phone, it wouldn't wake up.
I tried every single method to turn on the device, but it wouldn't work.
I even put my friend's S2 battery, but it wouldn't turn on at all.
Left it for a week in the charger but to no avail.
So in the end, I sold my DEAD S2, and bought a Note.
And yesterday, I left my Note to charge.
This morning, I tried to wake it up, it wouldn't turn on.
But miraculously after removing the battery for five minutes
then putting it back, it turned on.
So yeah I almost swore I wouldn't buy another Samsung.
I'm still in Samsung camp and in love with my Note.
PLEASE DON'T FAIL ME AGAIN.
That's my story, thank you.

I experienced the same thing with your S2 but on my Note. I ended up with having a DEAD Note. I sent it back to the service center for repair and hopefully for replacement since it still has warranty. I had to admit, I haven't tried to remove the battery on my Note for five minutes before putting it back in.

Check out this thread: My phone suddenly shut down I think your phone may not have died, but the screen just wouldn't turn on. A kind of coma-like thing, rather than a sleep of death. It's been happening to a few of us and seems to be benign, so far. It's happened to me just 4 times in 2 months. One of the times I was able to get the screen to turn back on when pushing the home, power, and volume buttons randomly. A battery pull always works, but rebooting by holding the power button for 10 seconds also works.

As I mentioned in the other thread, I did every button combination even after a battery pull. I even tried to use a different battery altogether but to no avail. I'm just curious, how long did you have to wait before you put the battery back into the phone after pulling it out?

I'm very sure it's not a coma. It's permanently dead. Used a JIG, it wouldn't turn on either. Left it charging for a week without removing, wouldn't turn on. But if my S2 didn't die, I wouldn't be owning a Note now.

Maybe there is some power spikes at your end? Having both phones the same problem seems too much against the odds.

Battery drain while tablet is turned OFF

I was using my Nexus 7 til it hit about 15% and the battery alert came out. I turned it off, plugged into the charger and left it there overnight. The following night I took it out of my pouch only to realise that its very warm. I had to press on the power button for a good 10 seconds before it turned on, and when it booted up the battery had only 5% remaining, even though it was fully charged (I checked to make sure it was 100%) and was left OFF the entire day.
I encountered this before but thought I solved the issue after wiping the device and flashing CleanROM 3.0 without any custom kernels or tweaks. Looks like the issue is back, any idea what might be wrong? I hope it has nothing to do with the physical battery itself because that would be a pain. Other than this, the day to day battery life of the tablet and stability is pretty good.
BUMP
No one really? Im sure there are people who experienced this before.
My wife's phone does something very similar. Crashes, heats up and when she gets it back on the battery has taken an absolute hammering. Luckily it occurs only rarely and it appears that there are no long term consequences.

What phone is she using? Is it rooted?
Anyway I think i figured out why, i happened to notice it by chance. After full charge, i plug it out and notice the screen is actually turned on even though the device isnt! The screen is just showing a plain blank screen, but you can tell its turned on, by looking at an angle. I had to manually force a shut down by holding the power button before it goes off, then the tablet automatically switches on. It seems that it only happens when i charge the tablet while its switched off, I wonder if it has anything to do with the bootloader (Im on 4.2.1) or the charger itself.
Galaxy s2 rooted, does not appear to be rom or kernel specific as it occurs with different combinations. Anyway good news you have at least identified the problem.
Cheers Danny
Sounds like it never charged. Why turn it off to charge it? Airplane mode is just as good.

It did charge because when i turned it back on it showed as 95%, the first 5% was drained because the screen was left "on" the whole time. I am beginning to suspect it is the case I use with the tablet. Its similar to those smart cases on the iPad where the screen auto ons/off when you flip or close the cover. I notice that even during the process of shutting the tablet down the flap still affects the screen off/on when i close it. A potential way of screwing up stuff. Next time I charge it turned off, I'll try removing the case entirely and see what happens.
Alright this time I turned the tablet off and left it to charge over night WITHOUT the casing and now it's working fine. No screen on or any heat whatsoever.

Why are you turning it off to charge? Just plug it in and be done with it. I never turn any of my devices off - the only time my S2 has been off is to reboot to flash a new ROM. Never have any charging issues.

Its just a habit i guess, and i always have the mentality that it makes a difference charging it while off
And its also good to reboot your phone once in a while, I usually do it once every 24 hours of use. Y'know, to flush out the RAM and OS so it can start anew. :highfive:

[Q] Nexus 4 turned off by itself?!

Hey everyone!
I recently left Samsung and decided to try out Nexus 4. I actually planned to test it out so I kept the plastics on the charger and everything, and left everything in the box because I want to sell it for the Nexus 5. Anyways, I've used it for exactly a week now and it's been working just fine, but last night was the second time I left it charging overnight. Since I kept all of its stuff in the box, I use the charger from my Nexus 7 to charge it. It's been working fine so far, but today I woke up from my alarm, took my phone off charge and it worked perfectly. I went back to sleep with the phone beside me and when I woke up, it wouldn't turn on. Anyways, I got really worried and eventually it safe booted when I pressed power + vol. down. I pressed "Start" and now it's up and running but when it powered back on, it showed 85% battery instead of 100% considering it was on charge for about 8 hours. I know this isn't because of battery hibernation because I put it on charge while it was at about 4% I believe. I've looked around everywhere online and I can find people with similar problems but all of them have something like the phone going into hibernation or such. But Mine did not do anything like that. Can anyone please explain why this happened? The phone still has warranty but I really can't afford to go without a phone for 3 weeks if I send it in. Thanks so much!!!
P.S. It's running the latest KitKat, I've never rooted it, flashed it or anything like that. I am running the Google Experience Launcher.
Edit: I read that Nexus 7 chargers use 0.8 more current that the Nexus 4 chargers. Can that be the case? Thanks again guys!

I went back to sleep with the phone beside me and when I woke up, it wouldn't turn on. Anyways, I got really worried and eventually it safe booted when I pressed power + vol. down. I pressed "Start" and now it's up and running but when it powered back on, it showed 85% battery instead of 100% considering it was on charge for about 8 hours. I know this isn't because of battery hibernation because I put it on charge while it was at about 4% I believe. I've looked around everywhere online and I can find people with similar problems but all of them have something like the phone going into hibernation or such. But Mine did not do anything like that. Can anyone please explain why this happened? The phone still has warranty but I really can't afford to go without a phone for 3 weeks if I send it in. Thanks so much!!!
P.S. It's running the latest KitKat, I've never rooted it, flashed it or anything like that. I am running the Google Experience Launcher.
Edit: I read that Nexus 7 chargers use 0.8 more current that the Nexus 4 chargers. Can that be the case? Thanks again guys!

Charger could be one problem. It's better to use the stock one.
What you had there was a BSOD ( black screen of death). Basically, the cpu gets stuck when trying to sleep. Software issue. Battery consumption is higher. Plus a reboot may have taken some more battery.

Phew! Thanks!! I was so worried that this was a hardware issue! I am a developer so I was testing out a tetris app yesterday, that can be probably cause I guess. Or maybe that just happens to the CPU sometimes. I've never done anything to overload it or anything but maybe it was working too hard to control all that extra power it was getting from that Nexus 7 charger. But that makes alot more sense! I was really worried because I baby all of my electronics and I would hate to have to send my phone into Google or for anything to be wrong with it. Software issues can all be fixed with a factory reset right? Thank you so much! I was extremely paranoid! Thanks!

Nexus 6p Turning off and won't turn on until plugged in

I recently had my nexus 6p battery replaced. I was told it was replaced with the Huawei brand battery. The capacity seems to be normal again. However, I have noticed that my phone is randomly shutting off about once a week. It will go from using it to just completely blank screen and off. The battery will be at any charge percentage, but when I try to turn on the screen or turn on the phone, it just stays blank. It only works if I plug the phone in, wait for the charging indicator, then I can unplug it and turn on the phone..
I have noticed this has happened when I opened my camera app and when I opened snapchat. I think this is a coincidence, but I am unsure.
I noticed when I plugged the phone in when it had turned off, I noticed a very feint red flash of light below the ear piece. This is supposed to be where the light sensor and proximity sensor are at.
I had it happen again to me when I was opening Android Messages when I was with one of the repair guys that replaced the battery. I used a USB A to C cable to plug it into a computer and then into my phone to show him that plugging it in jump starts it and the battery is not dead. However, this resulted in a bootup, then blank screen. Leaving it plugged in has it bootup and then blank screen and back to off animated charging. Thinking phone was dead dead, I went home and tried to call warranty. In the process, I plugged it into my computer, USB C to USB C and the phone turned on and booted up. My computer has a thunderbolt 3 port. My guess is the power supplied by the USB 2.0 type A port was too low to give it the jumpstart. But when I plug it into the chargers I have at home, which are more powerful, it is enough to jump start it and get it working again. Maybe it is a coincidence about the different charger outputs.
Any thoughts?
I think it might be a battery issue and people were telling me it was part of what's going on in that lawsuit.
Only cheap battery's available for the 6p unless you get a ceno. I purchased a battery from eBay supposed "OEM." The first one did exactly what you first mentioned. Early shut downs and failure to turn on. I didn't even get those with the original battery just that it was getting bit tired. I messaged the seller and he gladly sent me another no questions asked. I've had that battery for 3 months now no battery sensor but works great. I wouldn't hesitate to order another knock off but will make sure it works this time before I put the back cover back on!!! So in other words there's nothing wrong with your phone just that your battery is a lemon. The fact that it's the original battery your having problems with is even worse. If you like the phone spend the $100 and get a shop to replace the battery.

I had the same issue, I tought the new battery was defective or false but it was because android 8.1 developer preview 1. I went back to android 8.0 and the issue dissapeared.
Hope it helps.

This is great to know, thank you. I'm having exactly the same problem as OP. I replaced the battery myself, I have no doubt that the battery is a cheap knock-off version even though it's got the Huawei branding and regulatory info on it.
I'll order another battery and see what happens. Cheers
I got the battery replaced and everything is great. Great battery life and no more restarting and locking up. Definitely was a battery issue.
what's the name of battery please?
Don't buy cheap knock off batteries. Remeber the original battery has a pretty fat ribbon cabble and also has the temperature controller built in the battery here's a pic
any link?
Probably Oreo 8.1 issue

I have the same issue as everyone else posting here, except my battery is the original. The battery performance follows normal usage patterns. This means when I charge it, it eventually reaches 100%. When I'm normally using the phone on battery, it slowly discharges. Any phone acts like this.
My problems started when Oreo 8.1 was first installed. Other than being on the beta channel, this phone is not altered, or rooted.
Within fifteen minutes of using the phone heavily while on battery, the phone decides to shut down. The bars at the top and bottom of the screen turn bright red, the screen is greyed out, and it says "Shutting Down" in the middle of the screen. I have not traced this to any particular activity of mine. Usually just reading news or mail. When the phone shuts down, restarting will not work. It gets to the "android" screen, and shuts off again..
When I plug it into the charger The lightning bolt battery shape appears on the screen. Then the filling battery is shown, and it starts filling from very low. The second cycle of the filling battery starts filling from where I expect it to be: in the 80-95% range the phone was at when it crashed. At that point I can restart the phone, while plugged into the charger or not. The battery level indication after the phone is back is exactly what the battery was charged to when the phone crashed: usually 80-95%. I do not think it is a battery problem. I think the battery monitoring software is being interfered with.
Usually I can listen to an audio book with the screen off for a long period of time without triggering the crash. This does not require any network activity. Maybe that's a clue. Also, I have never crashed the phone while it is plugged into the charger. Maybe when the phone is in charging mode, the low battery monitor is not active, so it can't shut down the phone.
I have started putting adb into tcpip mode, and I've captured a few system logs of the phone as it crashed. There is no obvious crash at the end, but there are always a series of strange events, such as permission denials, and processes being killed. I think there may be an out-of-memory condition occurring. There is so much noise in the form of security violations being inserted into the log that it is difficult to determine which error is leading to the crash.
Perhaps I should try going back to Oreo 8.0.
