2013 Nexus 7 randomly reboots, not sure how to troubleshoot. - Nexus 7 Q&A, Help & Troubleshooting

This behavior started within the last month or so.
My Nexus 7 randomly reboots 2 or 3 times per day most days, but not every day. It's running the factory ROM and it's not rooted. It rarely reboots when it's actually being used. Usually the reboots happen when it's sitting idle. Googling around led to suggestions to take a bug report immediately after it reboots. I have a couple, but I don't know what I'm looking for in them. The files are over 111k lines long so it's not like I can just skim through the file. How can I go about finding out what's causing the tablet to reboot?

Try the nexus 7 2013 forum this one is for the 2012 version it may be worth trying a factory reset failing that reflash the factory image also try booting the tablet in safe mode this limits the apps to only system apps if the tablet stops randomly rebooting then you know its a 3rd party app causing it

Random restarts

The past week I got 3 restarts on my note. First was at home with USB cable to PC to charge it, nothing else, locked screen, don't remember if there was a running app. The other 2 times where on the road, I was listening music on stock music player. The only app I am thinking it could have something to do with this is top deals, even not 100% sure need to confirm got rid of it now let me check it. Anyone else noticed anything similar???

It happened to me few days back. It did not restart but I found it was off. Battery was around 50% and it was on third day after restart. I think it could be remote desktop app called 2X - Note particularly gets slow after runing 2X couple of times. I am on 2nd day without running 2X and I wish to confirm if this app is playing something wrong (btw I didn't have problem with 2X on S2).
Yup. It does happen to many people. "Sleep of death" happened to me several times on stock speeds/voltages. Restarts on my phone seem to be more OC/UV related.
I got mine about a week now and have had several restarts. It was way worse before I ran the update though... Now it "only" reboots 0-3 times a day
I don't dare to root it before I know it software related, but it seems like that since it got better with the official update...
I have restored it to factory defaults etc and nothing helps. I experienced this with NO extra apps installed and with the 4 apps I installed it's not worse. (Don't wanna personalize it before I root OR send it back and hope for replacement.)
Third day and it restarted. It however did not reset System Uptime.

Never had a random restart or sleep of death, in fact I can only recall 1 FC and I've had the phone for 2 weeks now

Lucky you!
Well what I wonder is if I root it is it possible that a custom ROM will fix my problems?

I'm gettin random reboots / restarts...

Really weird, doesn't seem to happen when the tablet is stressed or something. On the other hand happened more often with heavy memory stuff like big pdf's and when i live youtube videos loading, maybe I have an issue with the 2 gig's of ram? it's there any way i can test that?
Sometimes the tablet isn't doing anything an restarts. Like when the home screen is blocked. Anyone else had this problems?

I would suggest you try flashing the nexus 10 factory restore image and see if that fixes things. If it's still randomly rebooting I'd send it in for a replacement.

I'm getting the same, please keep us updated because I'm hoping it's a software issue...
Got some of these too. One of these was really freaking, I had to force a reboot. I definitely think it's software

i have also problems. Sometimes when i usw Chrome, the Browser don't react and then the screen goes black and i have to push the button on top for five seconds to reboot my nexus. Had this problem three times. I,m hoping for a fix...
Happened to me twice already! Wtf

Guys, I think found a pattern: Each time I get a reboot seems to be related to the wifi connection, like if the wifi freezes the tablet. Pay atention to the wifi settings when you get reboot / restart the tablet it's like searching the wifi connection like crazy, but, if you reboot normally the wifi it's already connected. Seems like a clue to me.
I played like 4 hours yesterday Chaos Rings. Seems like a really advanced game to me, so the stressing test is passed. It's not related to stress IMHO.
I've been getting random reboots too. Took several attempts to get all the way through setup right after taking it out of the box. At first I thought maybe I just hadn't given it enough time to acclimate to ambient temperature or something, but problem has persisted even after flashing the factory image via fastboot. Haven't noticed a correlation with wifi, but does seem to happen mostly when idle. Have also had a couple freezes and shutdowns, too.
Guess I'll be calling Google this morning... Argh.

I actually haven't had any reboots yet. I haven't stressed it with any games, but installed my normal apps and used it for web browsing/xda for a couple hours and no problems for me (yet...fingers crossed)
Called Google, and after being on hold for almost 1/2 hour (I'd imagine they're pretty swamped) explained the issue as well as what I've already done to try to resolve it (factory reset, fastboot recovery image flash) and they started the replacement process without any additional questions.
Just my luck, the first time in ages that I buy a device the day it comes out, I end up with a dud... Hopefully I get the replacement quickly!
I'm really nervous at this point. Mine is perfect aside from a piece of dust in the screen. Google is sending me a new one, but now I am afraid I will get one with more issues.
no more reboots here. But i think it's a software problem.
I have had two unexpected reboots. One was about halfway through ep. 1 of Planet Earth. I don't recall what I had running the other time.
I'm still running stock 4.2, unrooted.
Somebody postes useful info.

Mine rebooted then rebooted three times in a row before even getting in the desktop.
+1 Reboots
3 reboots in the past hour! Location svcs disabled.
Sometimes under load (gaming), other times just random.

My N10 Keeps freezing and resetting

It has happened several times caused by various apps such as chrome, play store, dolphin after downloading something. Screen freezes and system eventually resets on it's own. Is anyone else having this problem?
Build: JOP40C
Same here, restarted and frozen 3-4 times in couple of hours.
I was browsing, using apps, dowloading in background, loads of syncing etc - maybe taxing the system causes it? (But i though it should handle it a bit better...)
I had a couple of reboots but no freeze before the firmware update.
After the update it hasn't rebooted but it froze once

I've had exactly what you are saying. I had it three times and haven't had it since. Will update if problem persists.

My keeps loosing Wi-Fi and completely shut down every time I turn it off and didn't turn back on in 5 seconds. Making things worse I have to wait several minutes until it allows me to turn it on by pressing power for a 5 seconds. In those few minutes it does not react on power button at all.
Factory reset did not help. Sadly it looks like I have no options other than return it back.
+1 reboots and freezing. Don't really want to return it since its finally rooted and cust recovery. Anyone think waiting for cust Roms will help?

No need to return the tablet for software issues.... Updates will come quick. That's a Nexus!!!

Mine had been randomly restarting after installing some of my apps. I finally narrowed it down to HD Widgets and haven't had a reboot since uninstalling it.
I am not using HD Widgets and I get restarts periodically. What is the most efficient way to submit a bug report to google.

Just got an RMA for mine for the same issues u guys are experiencing. Wifi disconnecting and chrome freezing and rebooting. Looks like it may not be a hardware issue. Wonder if I should just keep it and wait for an update.
Edit - It was fine before the software update. Probably should ignore it once I get my replacement unit
I am also seeing the reboots happening every 3 to 4 hours like clockwork. I didn't have the device for more than a few minutes before the first update was pushed to it, so I can't say whether or not that was related. I do have HD Widgets installed, so I will pull it off and see if that helps slow the reboots down.
I'm using BootLog Uptime to keep track of the number and frequency of reboots. If this pattern holds, my money is on some kind of memory leak... just thinking from our own development experiences. Given how much higher the resolution is on the N10, I wouldn't count out some graphics heavy apps blowing through their heap much, much faster than on any previous Android device. We'll have to wait and see.
Just called Google and asked for replacement. I hope they aired new updates at the time my replacement arrived.
BTW, I had to initiated factory reset five or six times until it finally clears all data. Never saw Google product so buggy before.
That's a real bummer. Mine doesn't reset or display any of those problems. I have a tiny bit of light bleed in one corner at full brightness and the screen seems to have gotten a little more yellow over time... maybe just the glue drying. If any of you are brave and don't want to return right away, unlock the bootloader and reflash the stock image from google and see if that fixes things. It can help if there was some sort of corruption when you updated.
You may want to wait on that RMA. I had the same trouble with HD widgets installed.
No trouble at all since uninstalling...

I've never even touched hd widgets and have had two lock ups since I got it on Friday. Both occurred when task switching back to chrome and it was loading a previously viewed web page. Both times I was able to tap the power button to shut off the screen but couldn't wake it up. It eventually reset itself. It boots in like 5 seconds so it's not too terrible to wait for a software update, but I wonder what is causing it?
I think Chrome has some major bugs to be squashed when running on this device....mine has only crashed when browsing. That said, after uninstalling HD widgets, no crashes since...

I'd like to update my results. From last night, just like djflan, I removed HD Widgets and so far, 7 hours later, the crashes are gone. So I have my fingers crossed that I've found my culprit.
Also, I installed the HoloWeb browser and I have found it to be quite a bit quicker and more stable than Chrome. For those of you have issues with Chrome it is worth a few moments to track this app down (here on XDA) and give it a try.
Some of you may not have remembered or gone through the Android 3.x transition, but these kinds of issues were very prevalent during that update as well. Many developers simply don't or can't test on a wide enough range of devices and OS combinations to catch all the issues, or they rely heavily on assumptions or code that "always worked fine" in the past. I think we're seeing the same sorts of behaviors again with 4.2, so it will take a couple of months for it all to shake out.
For now I think I have a stable configuration on the Nexus 10 and I'm sticking with the device. No RMAs will solve issues that are software related in my case.
Removed hd widgets, no crashes yet.
I get the same random reboots and I've never used the fancy widget app. it has happened 3 times already. One I was browsing, another time deleting a widget and the last one when I tried to change the wallpaper. Everytime I had to hold the power button 5-6 seconds until it reboot

I spoke to soon earlier... I actually had 2 restarts today. Once while chrome attempted to open a link from tapatalk and another while trying to load one of the free magazines in the play app.
I don't have hd widgets installed either

[Q] Phone shutting off randomly

Have had my nexus 4 for 2-3 weeks and it has shutdown on me 2 times so far. Both occasions the phone was untouched and was shut off without me knowing, how long and when I have no clue but on power up my wallpaper is reset to default. I don't notice anything else besides that being changed. Anyone have a clue to a fix?
What ROM u have? I'm having same issues. I'm using Xylon. I'm bout to flash Franco #28 kernel and see if it helps.
U should try flashing a new kernel too.

bone stock. haven't done anything to it.
I also get something similar. It happens when I lock my screen. Once the screen goes off, it sometimes won't come back on until I restart my phone by holding down the power button till it's off, and then booting it. I'm not sure about my wallpaper changing, but it has happened on every rom I've used. Also, It didn't happen on stock, but I don't think I was even on stock for a week.
This never happened when I had stock...it started happening when I flashed the ROM. Hope Franco's Kernel helps.

this happens to me from time-to-time. It's not a hardware issue, it think it's a glitch with this version of the os.

Well, I called and got an RMA. Seems like a known issue as well as a battery life issue some others seem to be having. Maybe they are connected in some way. Rep said this new batch they are sending out (RMA's) do not have these issues. I hope so...
Put me down as someone having this issue, Happen 3 time now, On stock rooted os.
I read that Google have confirmed there is an issue with the latest OS that can result in random reboots. I think it has to do with location services.
I also read that turning off any options for emergency broadcasts can help with random reboots.
Some widgets that use weather can result in reboots (due to them using location services to get correct weather), and since I disabled all emergency broadcasts and stopped using widgets that show weather, I have not had a random reboot (and I was having at least one every two days before). I am still using widgets that have the ability to show weather, but I just do not show weather and this seems to help.
Random reboots was causing a major battery drain for me and since I stopped getting these reboots, my battery lasts much longer.
I am on stock ROM, rooted.

Nexus 10 Random Reboots Fixed

I'm hoping I have fixed my Nexus 10 random reboot problem by installing the free "Wake Lock Power Manager" by darken from the Play Store.
Since upgrading to 4.4.2 I've been experiencing on average 3 reboots a day with 7 reboots on some days and a total of 81 reboots for April.
I installed the free "Wake Lock Power Manager" app early yesterday morning and I've not had a reboot since then.
I've used the setting which keeps the Wakelock always on as shown by the Wakelock icon in the notifications bar.
I think it might keep the screen on permenantly too but as I normally use my Nexus 10 with the magnetic Pogo charger lead connected that is not a problem.
If the random reboot problem returns then I'll report it.
Update.
Still no random reboots since installing the free "Wake Lock Power Manager" by darken after two-and-a-half days which is a record for me. So I'm feeling more confident that I've found a solution to my Nexus 10 random reboots.
I've kept my Pogo charging lead connected all the time and I've not done a power down since installing the "Wake Lock Power Manager" app.
I would be interested in knowing if the app has worked for anyone else.
I find this post very odd as I've had my N10 for over a year now, rooted, used a few different custom ROMs, returned to stock and only had reboots with few bad custom ROMs releases. If your on stock there is no way you should be having that frequency of reboots. If you are on a custom ROM then go to something another. Other than that do a factory reset or reflash stock and slowly add back apps until you find the villain.
From what I read in your posts it seems you only masked the real issue which means it will be that much more difficult to resolve the next time it bites your butt.

Thanks for your reply and your suggestions.
I'm on a stock ROM and I agree that I should not be having that many reboots, although it seems it's not rare judging by the number of similar posts on the Web.
I've tried a factory reset and downgraded to 4.3 which seemed to solve the problem, but I kept getting upgrade reminders from Google which I eventually did hoping the problem was fixed and went back on 4.4.2 but my reboots re-started.
I even got reboots after a factory reset with no apps downloaded other than those Android system apps which came with the factory reset so that seemed to rule out a faulty 3rd party app.
Without the Wake Lock app I would probably have had about 9 reboots over the last 2.5 days so I'm happy with that even if I'm just masking the problem.
I've read reports that the random reboots that some people are experiencing might be fixed with 4.4.3 due this month which would be a better solution than usin an app.
Another day has passed without a random reboot and I'm growing in confidence that my reboot problem is fixed, bearing in mind that used to get up to 7 reboots a day.
I'm enjoying my Nexus 10 much more now that I don't have to login and restart apps several times a day.
I wish I could hear that it has worked or failed from someone else to see if others with the reboot problem get the same result as me.

After reading this, I installed the app and started it with PARTIAL_WAKELOCK. No crash in 6 days, that's the longest period in ... ever!
I'll try the even less aggressive settings next.
Changed the setting to WIFI_LOCK_SCAN_ONLY, and the tablet rebooted within 2 hours.
Since I got the kitkat update, my nexus 10 start presenting random reboots. I tried everything to figure out the reason but with no luck.
However a couple of weeks ago I recharged the tablet using the micro usb port instead of the pogo pin connector (I've been using the pogo pin connector to charge the device since the cable was released) and then no random reboot occurred since.
I've read this tread and it seems everybody here that has been experiencing the random reboots is using the pogo pins to charge the nexus 10, right? Can anyone test if it will work if the micro usb connector is used for charging?
