I got 1 reboot in the middle of watching a youtube vid, all of a sudden, the video began to stutter and repeat the same frames over and over again, after that i heard the pop sound of the speakers , the screen went black and it rebooted.. While rebooting, i was able to hear a weird noise, like the noise of the fan of the cpu cooler on desktop computers, it lasted for ~3sec and then normally logged in to the homescreens.

Unlocked and rooted, but fully stock.
[Nexus 7 General] daraldf:
My N7 randomly rebooted tonight. It was sitting on my desk and all of a sudden I saw the Nexus logo. I don't think it's done that before.
[Nexus 7 General] AFAinHD:
Did anyone that posted here have a custom kernel when your device rebooted? Coming from someone who tinkers with Linux every once in a while, this sounds exactly like a kernel panic. Google may have updated the stock kernel and messed something up.
[Nexus 7 General] bustinstugots24:
I've had a random reboot about 4 or 5 times since the latest update. Stock kernel and rooted. It's just frustrating. This update was a big mistake. Battery drains faster than ever and tons of lag, especially when dealing with screen rotation.
[Nexus 7 General] idevice12345:
My battery drains very quickly
[Nexus 7 General] AFAinHD:
Click here.
[Nexus 7 General] magpie22:
Mine has done it 5 times now since the update, so i have removed all my apps and done a factory reset and i am keeping it that way for a few days to see if it will reboot by itself because i honestly think its some rogue app that is not 4.2 friendly.

I am not rooted and Nexus has never been rooted.
[Nexus 7 General] emylia777:
keep us updated regarding your finding. :o
[Nexus 7 General] mscha:
Me too...

About once or twice per day, random restarts, without warning.

They're definitely not full reboots: according to Settings / About Tablet / Status, my uptime is 112 hours.

My Nexus 7 is completely stock, not unlocked or rooted.

4.1.2 was rock solid, in the 5 or so days that I had the device before the upgrade.
[Nexus 7 General] xdracco:
Add me to the list...

Rooted 4.2 using Mark Skippen's Nexus 7 toolkit (updated Oct 12). The last random reboot was while it was sleeping about 5 minutes ago. I just happened to notice the boot logo (the colorful X). Again, tablet was sleeping when it randomly rebooted. I've noticed random reboots at other random times but nothing consistent. I thought Firefox was the culprit so I uninstalled Firefox but issue persists.

These are not full reboots as uptime doesn't reset to zero.

Bummer.
[Nexus 7 General] magpie22:
Well so far today I have had no reboots after getting rid of all the apps that I usually have on this tablet. Still early days but so far so good.

Uptime is 9 hours but the big test will be overnight as that seemed to be when it happens the most.
[Nexus 7 General] jwsg:
Random reboots seem to have stabilised now (the Google X just appearing when the N7 is idle) and although at first battery life seemed to have improved when left idle, today has been a disaster with it getting noticeably warm just surfing tethered and the battery life becoming worryingly short.

In case anyone is feeling statistical mine is rooted with no factory reset after upgrade. I'd better whisper the next bit for fear of upsetting anyone, but 4.2 has stolen my prized N7 and left me with something unrecognisable instead (no USB mount, power draw...)
[Nexus 7 General] AngeleDei:
Random reboot s here after turning itself off for no reason. Had to long press to get it back on.

All apps are up to date. Stock 4.2, unrooted, 3g nexus. Just uninstalled go SMS pro as that was the last app I installed.

I was using chrome and this site both times it rebooted.

Oddly, the virus checker I have just said, scanning new software which is weird as î gave not installed any. Other thing I'd done was uninstall twitter.
[Nexus 7 General] miki67:
No more random reboots since I have updated some apps, first of all Dolphine Browser with JetPack and Firefox 17.
[Nexus 7 General] Devhux:
Had a random reboot last night while using Xscope Pro browser. First one I've encountered so far.
[Nexus 7 General] Jimjk1968:
I had only one of those since updating to a 4.2 ROM. I think early stages of a new os were just going to have those off and on. :)
[Nexus 7 General] formicae:
Installed 4.2 using the factory image and the bootloader, had 3-4 reboots last night. Curious to see if it gets better as apps get updated.

Kind of smells like memory leaks to me, especially as it seems to be only a framework restart and not a full device reboot.
[Nexus 7 General] phonic:
I've had two random reboots since getting my N7 3G. Both were within minutes of me actively rebooting the device.

HOWEVER, they weren't normal reboots. I noticed the X boot screen, but it was only present for a few seconds, and then my tablet was back up. But when that happened, I lost WiFi completely. Had to reboot to get it back.

I'm also using a custom kernel, so that might have something to do with it.
[Nexus 7 General] nicatronTg:
I've not been having reboots, but massive lag on just about everything (even after a factory reset). Unlocked with no root.

The reboots are probably caused by the Android Framework crashing, judging by the fast reboot times. If the Framework restarts, generally it only takes 3-5 seconds for it to come back online.
[Nexus 7 General] AngeleDei:
Oh and I checked what applications were running after deleting Go SMS Pro. I had 2 instances of Google Maps, HD Widgets, AVG, 2 instances of accuweather, some internal google apps (including setup and keyboard) and that was it. Battery was at ~59%.

Since the kernel panic (needed to long press to turn on) and two reboots within 5 minutes of it while in Chrome, I've had no issues. I deleted GO SMS Pro and tried to kill the GMap applications, but they are both back now. Since then, nothing... so far. I've got it sat in chrome with a half edited reply to see if it reboots at any time.
[Nexus 7 General] magpie22:
Well mine is behaving perfect since i removed all the apps and done a factory reset, have not had a reboot in over 24 hours.

It has had plenty of use as well, streaming google music, using chrome and the battery life is back to being very good with a 44% of charge left and uptime is 1 day 2 hours and 41 minutes,

So to me it is one of my apps that is causing the problem, but the hard part is going to be finding out which one, but to be honest i could live without some of them anyway.
[Nexus 7 General] styckx:
I've had two random reboots... Well. Not so random.. It seems for whatever reason when HD Widgets gets an update and it's installing.. It reboot the device.. Soon as it boots up HD Wigets finishes installing.

I gave 4.2 an honest second chance.. Pure clean factory image install using -w update.. Pure garbage.. Back to CM10 and I'll sit on that until they merge in the non-stupid parts of 4.2
[Nexus 7 General] revmra:
My 32G Nexus 7 and my son's 8G Nexus 7 are doing the same thing. He updated OTA. I updated with a reset and manual upgrade. It has happened twice in the span of an hour and a half for me today, although I don't think it did it yesterday--at least not while I was using it. The first was when HD Widgets was updating. That happened when I updated Tapatalk a day or so ago too. That REALLY makes me nervous that something got screwed up in the installing process. The second time it happened today was in the middle of playing Angry Birds Star Wars.

I don't really want to go through all of the hassle of reverting back to 4.1.2, but if this keeps up, I won't have much of a choice.
[Nexus 7 General] memleak:
Same here. Soft reboot just as the HD widget update is finished.

I had several reboots per day since the update.
[Nexus 7 General] revmra:
Trying to read the logcat makes me wish that there was a timestamp a la syslog.
[Nexus 7 General] kyo171:
i also got the reboot while updating HD widget. I get a feeling it might be a kernel problem.
[Nexus 7 General] magpie22:
Well I did put HD widgets back on and within 10 minutes I had a reboot, so I won't be using that anymore. I have emailed the developers but had no reply yet.

Without that on my nexus I have not had a reboot in over a day, so it looks like I have identified the rogue app that was causing my problems.
[Nexus 7 General] khaytsus:
adb logcat -v time
[Nexus 7 General] AngeleDei:
Spookily enough, mine rebooted when HD Widgets was updating.... maybe I should remove it too.
[Nexus 7 General] AraDreamer:
I think it rebooting during the update is less telling than that being the only non-google app and it still random rebooting. I've had this app and chrome cause more reboots than HDwidgets -Ara
[Nexus 7 General] jwsg:
Just rebooted to Google X while updating from Google Play - first I've seen in a day or so of stability.
[Nexus 7 General] styckx:
Has Google even acknowledged they sent us a steaming pile on a paper plate? So much for vetting issues and QA.. Just pack it up, send it out we have new hardware with a release of super limited supply to create a false sense of having a "must have' item on hand.

Can't wait till 2014 when they fix this..
[Nexus 7 General] BradleyR2010:
I've being having random reboots mostly when updating/Installing apps from the play store.
[Nexus 7 General] DominatingSystem:
I can confirm that hd widget causes the reboots.

But with the last update its gone.

[Nexus 7 General] FraserGJ:
Both times I updated HD Widgets I suffered a reboot, curiously after the reboot I still got the "successfully updated" appeared.

My reboot problems also began when I added a HD Widgets lock screen widget...
[Nexus 7 General] ezas:
Polite request. Everyone has a right to complain but don't word your post that makes it sound like you are speaking for everyone.

There are a lot of people running 4.2 both stock and the early custom ROMS/kernels with zero or only minor issues.

If you hate 4.2 say 4.2 has turned MY tablet into a worthless peace of crap and makes ME want to throw it through the front window at Google.

But it is very strange that so many people with truly stock tablets are have these hot boots. I hope you can find the main issue. The fact that it is all hot boots suggests a common cause.

[Nexus 7 General] jwsg:
No hate here, just some beta testing I think
[Nexus 7 General] formicae:
Reboot today updating some apps, but it was within moments of waking the tablet so I'm curious about HD Widgets. Disabling it for a while to see if it helps.
[Nexus 7 General] Caifan09:
No more reboots in 16hrs, using paranoid beta2.99. Also with HD widgets on the lock screen.
[Nexus 7 General] phonic:
In retrospect, the two reboots I had was during a Play Store update as well...
[Nexus 7 General] AngeleDei:
That gave me a laugh. Thanks! :)
[Nexus 7 General] kermitdefroghere:
For what it's worth, I was experiencing 2 to 3 random reboots per day.

I called Google play support who told me to (of course) do a factory reset.

He also said I was the only reboot complaint he'd had.

I was also experiencing brutal battery with CPU spy reporting deep sleep of only 66%ish. (I was used to 95% on 4.1.2)

After resetting, I'm now up to 36 hours without any reboots and deep sleep is back to normal.
[Nexus 7 General] DominatingSystem:
Ok, my restarts last night again...

I think a reset would be the best solution.

\\\... send with my Nexus 7 3G ...///
[Nexus 7 General] Maverick1707:
Factory reset won't help if you install back all the apps you had before... tested it myself.
[Nexus 7 General] bagou01:
I also get all the reported bugs

flickering screen with auto brightness,

random reboots on play store update

fast battery drain

less fluid then on 4.1.2

and slooooow charging (a full night almost doesnt fill the battery).

please google fix this
[Nexus 7 General] thesm4rt1:
same

Mine rebooted a couple of times after the update /:

have another user, maybe that's why?
[Nexus 7 General] bagou01:
don't think so, i'm a single user and i got reboots also, moslty during play store

---------- Post added at 10:29 AM ---------- Previous post was at 10:23 AM ----------

is there a way to set android back to 4.1.2 ? this was working so perfectly, why the hell did i jump on this OTA update :eek:
[Nexus 7 General] krelvinaz:
Just updated to 4.2..there were 30 app updates pending...Just did them all... been having lots of updates on my phone as well, suspect a lot of updates tweaks are taking place.

[Nexus 7 General] magpie22:
I am still clear of random reboots since I took HD Widgets off, so I am keeping it that way.
[Nexus 7 General] bagou01:
weird i also have HD-widgets on, maybe it could be linked ?

could you please keep me posted if you still get reboots? or if that solves other 4.2 issues like flickering or battery drain
[Nexus 7 General] roswell782:
No RR since i wipe and flashed 4.2 again.

Battery life is also good, almost 3 days, 3hours screen time, 44% left.
[Nexus 7 General] mortek:
Five days after a factory reset and installing all my pre-reset apps (and of course letting them update) and no random reboots whatsoever.

The overall performance is also improving along with the app 4.2 updates.
[Nexus 7 General] mirkuma:
Same happened to me. Reboot during HD Widget update! (Have been using HD Widget on the lock screen instead of "ugly" bold font clock...)
[Nexus 7 General] bagou01:
i'll try removing hd-widgets too and see if that helps
[Nexus 7 General] magpie22:
I have added some of my other apps such as sky drive, one note, ever note and a few others without any problems so far.

My nexus has only ever rebooted when HD widgets has been installed.

Another 24 hours should tell me if things are OK.
[Nexus 7 General] perthtrev:
All the same for me except my random reboots are just that "random" and getting more frequent, 4 today so far that I've seen. Pull your finger out Google and get it sorted or give us an OTA back to 4.1.2
[Nexus 7 General] AngeleDei:
Fix for the "missing December" issue is coming out before the beginning of next month, so hopefully they will fix other issues (like rebooting while updating, lag, battery issues, bluetooth) within that. To not do would be...short sighted.

[Nexus 7 General] revmra:
Since a lot of people are reporting reboots connected with HD Widgets, I uninstalled it. I'll see if reboots continue. My son also has that installed, so that would be a common thread. Interestingly, it rebooted when HD Widgets uninstalled. Nevertheless, an OS shouldn't let even a poorly coded app reboot the system. Having said that I did get a reboot once installing Tapatalk.

---------- Post added at 08:52 AM ---------- Previous post was at 08:08 AM ----------

THANK YOU! I had read some of the logcat docs but I didn't realize that that was an option. MUCH better.
[Nexus 7 General] magpie22:
Yes my nexus rebooted as soon as I hit the uninstall button as well. If it stays stable without HDW on then I might try Beautiful Widgets instead.
[Nexus 7 General] TheSlenderLoris:
+1 I'm also getting these random hot reboots on stock, rooted nexus 7 HD Widgets installed. Its making me very very sad:(
[Nexus 7 General] revmra:
Someone on the Google bug tracker said they got the reboots even without HD Widgets installed. It may just be that HD Widgets will trigger the bug easily.
[Nexus 7 General] joefrog1996:
4.2.1 WHERE ARE YOU!!!!!!
[Nexus 7 General] DominatingSystem:
This is the answer from HDWidget support.

But after I uninstall HDWidget the reboots are gone..

\\\... send with my Nexus 7 3G ...///
[Nexus 7 General] phonic:
I'm having the same problem with that beautiful clock app. Kept rebooting my tab. When I uninstalled it I rebooted again. Since then its been fine. So it is likely to be something broken with all third party lock screen widgets.
[Nexus 7 General] A.VOID:
I have HD widgets' but I got a reboot just using chrome on a forum page.

Obviously a bug.

I've seen some reboots installing apps and just general usage. Truly frustrating.
[Nexus 7 General] bagou01:
try removing hd widgets, it seems to be very present on all topics related to 4.2 issues.

i uninstalled it myself and since then no more reboot, wait and see...
[Nexus 7 General] AngeleDei:
So far (touch chip board), I've not had a reboot since removing HD widgets.

Battery life also "appears" improved (86% with an hour's screen using in the 7 hours its been off charge). But htat is probbaly a co-incidence.
[Nexus 7 General] TheIcemanCometh:
I initially started having this problem with my Nexus 4. I wasn't sure if it was some issue with the phone itself, and I didn't put 2 and 2 together with the 4.2 OTA update. I get several random reboots every day. I also have a Nexus 7, but it has not randomly rebooted. I have HD Widgets installed on the Nexus 4, but not the 7. I may uninstall it until they can get this resolved (assuming it's the culprit).

EDIT: When I uninstalled HD Widgets, I immediately got a "random" reboot.
[Nexus 7 General] bagou01:
maybe it's not hdwidgets fault but thre seems to be an awful lot of people complaining about the reboot who have it installed... and my personnal last reboot was when i uninstalled hdw... none since
[Nexus 7 General] Teranox:
I confirm I got those reboot on

Tap tap revolution

Dead trigger

Chrome

I think it has something with the processor (when too high or something)
[Nexus 7 General] bagou01:
i got a lot of these on play store.

so if chrome or playstore are too heavy on the cpu, they must have been coded by chimps :-p

by the way yesterday i played 1hr of need for speed most wanted without crash, so i don't think it has to do with hardware....
[Nexus 7 General] BobMiles:
I actually just got a reboot while uninstalling HD-Widgets. Now tell me, is this a goog or a bad sign ;D (Didn't remove the Lockscreen widgets beforehand - perhaps the Lockscreen was updated due to my uninstalling and caused the reboot?)
[Nexus 7 General] spikey68:
OK have HD widgets... Got reboots.... And a radio type sound in background of headset.... And battery not great.... Might be flash add on in Firefox.
[Nexus 7 General] adxgrave:
My first random reboot (unlocked, rooted, stock), not all the way though only starting from the X logo. I'm running chrome at that time.
[Nexus 7 General] TheSlenderLoris:
Exactly the same thing happened here, the choice appears to be putting up with the reboots or putting up with that pig-ugly excuse for a lock screen clock
[Nexus 7 General] spikey68:
I get Firefox and Chrome crashes after 2 mins+. Chameleon launcher sorted the ugly looks.
[Nexus 7 General] BobMiles:
I now removed all Lockscreen-Widgets (except for the Stock Clock which cannot be removed) in both my Nx10 and Gnex. Both were rebooting frequently at random times. Additionally I uninstalled HD and Beautiful Widgets...

Let's see and hope...
[Nexus 7 General] emylia777:
Got a reboot just now when uninstalling HD Widgets. Will monitor if it still has this annoying and sick syndrome after this. Hopefully not.. :banghead:
[Nexus 7 General] AraDreamer:
I restored to stock 4.2 yesterday, re-installed everything (including HD Widgets), no random reboots and increased battery/performance. Chrome gave me more freezes and reboots than HD Widgets, but lockscreen widgets are buggy as hell. But you gotta have one, so I'll try to not unlock/relock the tablet a lot. -Ara
[Nexus 7 General] Teranox:
Well, that make me think that I also have HD Widget installed on my N7. I also have it's widgets on my lockscreen.

Could it be related to HD Widgets then?
[Nexus 7 General] bstosnbata:
i have the same problem. my nexus 7 reboots randomly, it usually reboots when im playing youtube. i don't have hd widgets so i dont think its that either
[Nexus 7 General] aginies:
i got same problem, in my case i bought a N7 with stock 4.1.2 and i have done the update to 4.2, and i have got a lot of trouble.

I am currently testing the cleanROM-2.5 (based on JB4.2), installed after a full wipe data/cache/davlik. I hope my trouble are coming from the update from 4.1.2, and an full install will fix this bug.
[Nexus 7 General] formicae:
I'm curious about something. Some Nexus 4 users were mentioning reboots, and in the thread for Franco's kernel he says their interactive governor was acting up and suggested switching to ondemand. Trying it on the stock 4.2 kernel, will see if it helps. Not even sure switching it will work on stock.
[Nexus 7 General] akrapovic600:
Hi guys,

My N7 was having random reboots(especially after HDWidgets update), battery jump straight down from 90% to 35% and then started shutting down at 29%..Charging it up on a 1A output Samsung charger seems to be very fast as well..

And after reading this thread, i uninstall HDWidgets and all issue gone immediately..

Almost similar to my G.Nexus..
[Nexus 7 General] toyfj2k7:
Mine has worked flawless even with HD Widgets
[Nexus 7 General] akrapovic600:
It was working okay initially..

The latest updates provided the lockscreen widgets which i use..And since then having those issues..

Did u use the widgets HDW has on the lockscreen?
[Nexus 7 General] AngeleDei:
All I used from HD widgets was the clock on my main screen. Since I deleted it, the reboots are gone. I was Stable on 4.2 at first, even with HD widgets. I've not removed anything else to get back my stability. Been stable two days now.
[Nexus 7 General] BobMiles:
Removing HD widgets did improve stability, but the problem is persistent. This is definitely a 4.2 issue in my opinion.

Gesendet von meinem Nexus 10 mit Tapatalk 2
[Nexus 7 General] ailima:
+1 on removing HD Widgets. Many thanks to those reporting it.

I tried everything I could think of until I found that out. I removed HD Widgets and Executive Assistant widgets and then wiped cache and dalvik and it's much better since that. Not perfect but where it was unusable before, it's now totally usable without too horrible lag.

The charging problem persists however...
[Nexus 7 General] bstosnbata:
Hands down 4.2 problem. My n7 was working perfectly at 4.1, after 4.2 update i didnt install anything else, all settings was the same and i started having the problems.
[Nexus 7 General] bagou01:
Since i removed hdwidget i tôt nous more reboot but the problèms are still there... Flickering screen,less fluid, but thé battery drain seems lowered. Wait and see
[Nexus 7 General] radley:
HD Widgets possible work-around / fix

Hey guys,

Radley from HD Widgets here.

We don't follow this forum so didn't know there was big discussion going on. We're aware of the crashes and have talked to Google about it. They've confirmed it's not our app and are working on a fix.

Uninstalling our app seems to work, which is semi-good. I'm wondering if it could be related to the "no delete" bug we found. Basically, when you Remove a lock screen widget, it's removed from the screen but it's not actually deleted in the system (Google's aware and working on a fix). The result are ghost widgets in the system. Perhaps they're the culprit?

We added a work-around to manually delete ghosts. In the Active Widgets activity, select "More..." from the bottom menu, then tap "Delete".

Deleting these ghost widgets may fix the crashing. I'll run some tests to confirm next week when I'm back at work.
[Nexus 7 General] phonic:
A+ on the outstanding customer service by representing your company here and providing us with an update. I think I might go and buy your app just because of that. It's always warm and fuzzy when Developers show appreciation for their users/customers.

On a related note, it is NOT just HD Widgets. As I mentioned before, I had the same issue with other lockscreen widget apps (that beautiful clock one) which caused reboots up until (and including when) I uninstalled it. Hopefully Google fixes that quickly in 4.2.1.
