So is anyone else interested in helping out locating an app or something to see what is triggering the random reboots while its idle?
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
I found the old log tool. It wouldn't install.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
For those folks who don't know, starting in Jelly Bean, you can no longer capture debug logs on a device unless you are root. So if you don't have a full Android development setup or are rooted, there will be no system-wide logging capabilities for you.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Didn't know that. Thanks for the heads up. Not rooted and have only captured logs via adb otherwise.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
My device is rooted so what are some avenues I can take in capturing debug logs? I'm not keen on debug work so I wouldn't know. I'm just trying to get closer to pinpointing any possible reason for the random restarts during idle.

I'm leaning towards something that has a wakelock for data. Updating weather, the news, facebook, g+, etc, etc

Just want to see which one is the last one with activity before a reboot.

Thank you.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
We tell our customers who are rooted and testing to use Catlog (found here in the Google Play Store):

https://play.google.com/store/apps/details?id=com.nolanlawson.logcat

It works well, has filtering, and can periodically write logs to a file so you don't miss something. If you don't know when your device is going to have an "issue" that you want to log, it is probably best to be conservative and have Catlog save more often.

To make sure you catch every crash, we tell our customers to use Bootlog Uptime (found here in the Google Play Store):

https://play.google.com/store/apps/details?id=se.mumu21.bootlog

It will alert you with a Notification each and every time the device is restarted without you telling it to. It is an invaluable tool to use alongside Catlog to figure out when and how often a device is rebooting.
[Nexus 10 Q&A, Help & Troubleshooting] BobMiles:
So i just forced my nx10 into a "random reboot" by installing hd widgets, adding two lock screen widgets, setting one of them as the default instead of the stock clock. Then, while listening to Google play music, uninstalling hd widgets will definitely force my nx10 to reset.

I logged everything with catalog and here is the beginning of the mess:

Notice the Hardware render problem and the Apollo 13 to Houston like emergency callout...

After that, it's all errors with android.view, accessibility manager, viewrootimpl and something called Zygote...

Does this mean anything to anyone? As I said, the above procedure definitely leads to a reset on my nexus 10. Can you confirm that, or is it just me?

Edit: There seems to be the root of the problem, this was logged before all those errors and before all those services died:

Seems to me like HD widgets is blocking a file and is then killed by the system, which ironically kills the system itself?

[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
I'm certainly not an expert, but it seems that HD Widgets attempted to draw something, failed at that, hung while opening a file then blew through its allocated memory space, causing the OS to shut everything down.

My hypothesis from the start has been that there are people that are using apps that don't know how to properly handle the new N10 resolution and when confronted with the huge new display size, they overrun their memory while trying to draw something. These logs don't exactly confirm that, but they are an interesting data point toward determining if that is the issue.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
Here is my logcat before it restarted on its own during idle. Any clue as to what might have happened?
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
johno86, from the little bit I could see, there wasn't anything obvious or wrong in that image.

For future posts, it would be easier to share the actual log files, as they contain more information than the screenshot shows. If you are worried about privacy issues, you could always PM them to interested parties directly, rather than posting them in the forum.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
Just for you guys... I reinstalled HD Widgets again and started up logging on our N10 device here at work to see if we can see where the issue might be. I managed to get the tablet to crash, as I had before, within a few minutes of adding the HD Widgets weather widget to the lockscreen. We'll see if we can come up with any ideas and report back once we know something more.
[Nexus 10 Q&A, Help & Troubleshooting] BobMiles:
Did you set the save period to every line (instead of every 200 lines, as is the default setting) otherwise you probably won't see the relevant log entries as they won't be saved.

Gesendet von meinem Nexus 10 mit Tapatalk 2
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
I've uninstalled beautiful widgets and got rid of news and weather widget and the crashing stopped for now. Running logcat now to see if anything else is causing it. I'll PM you the entire logcat If it crashes since you seem to know what to look for.

seems like the crashes are related to a widget refresh. We'll see..
[Nexus 10 Q&A, Help & Troubleshooting] DaMan90:
Guys try disabling Google currents auto sync. Just open it hit menu settings and that should help a little
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
We're setup to save every 10 lines, and we've already seen one crash.

The issue here is that even with a full log, the crash isn't pointing to anything obvious. We have some theories, but we may need to make our own app, Recast, onto the lockscreen to find out and fully log what is happening. It is a really strange way to crash, that's for sure.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
I set mine up to save every 1 line. I've disabled everything with an auto update or auto interval update on my device. No restarts yet and still running logcat. So far my theory that an app or widget that automatically pulls interval updates are causing it seem to be one of the reasons for the restarts. Will keep testing as I'm fed up with the restarts. I'm going to get to the bottom of this bullcrap.

Mstroud could you PM me your email so I can send you my log? Tried to PM it to you and it said it was too large of a message

Device crashed again and it wasn't running any widgets with auto refresh.
[Nexus 10 Q&A, Help & Troubleshooting] Droid_Junky:
Deleted HD Widgets and turned sync off for currents. No reboots in 26 hours. Before it was several times a day.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
johno86, you can send it to our general support email address: support@phase2industries.com

Just mention that it is about the Nexus 10 reboot issues so we don't mix you in with our customers :)
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
Thanks. I just sent two emails to your support with catlogs of separate events involving a reboot. Hope you can pinpoint something.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
johno86, thanks.

A quick look doesn't show the crash in your logs, unfortunately. But the remainder of the logs appear very close to our N10 output, so at least there isn't anything very different happening between the different devices that we can see so far. That is a good thing, as it means that someone will eventually be able to track this issue down, we hope.

---------- Post added at 04:50 PM ---------- Previous post was at 04:02 PM ----------

One last update for the evening:

We have our N10 setup as follows: we have shutdown all unnecessary apps, removed all system and 3rd party widgets, started no apps other than Catlog, Bootlog Uptime, and the stock provided items (Gmail, G+, etc.other than stock apps and services. Only one lockscreen widget exists, a weather widget from HD Widgets. The N10 is unplugged and connected to WiFi, Bluetooth is off, GPS is on and the stock screen timeout and lockscreen are setup.

In this configuration we can let the N10 sit, in sleep, for nearly 3 hours, with periodic wake ups for incoming email alerts, and then a soft reboot occurs. It is very consistent and reproducible, and our crashes go away immediately after uninstalling HD Widgets. We will have to do some more investigating to see if we can determine why this is, and whether or not it is coincidence that HD Widgets makes it happen for us but not other folks.
[Nexus 10 Q&A, Help & Troubleshooting] BobMiles:
I emailed the HD widget guys my crash logs and got an answer. According to them, it is a confirmed Google Bug, which has something to do with Location service. So at first this seemed a bit weird for me, but then I realised that hd widgets is using your location for weather and probably triggers the location check quite frequently...

[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
BobMiles, thanks for that, it is an interesting data point. It would also help explain why people who aren't running HD Widgets see the issue... as almost any app that has Maps or Ads in it rely on the same location services.

Funny thing is, when I asked the HD Widgets people about it, they claimed that no one was having problems with their product and that everything was fine with Android 4.2.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Would it be fair to say that turning off location services would bring back stability? Or is that an unknown at this point?
[Nexus 10 Q&A, Help & Troubleshooting] multimolti:
same here, happened to me 5 times so far (received the nexus only 6 days ago, so roughly once a day). happens especially if i used for for a long time and many apps are running in the background.

i dont have and never had hd widgets installed, so that can not cause my problem. but i disabled the currents auto sync and hope it wont crash anymore...
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Can someone with consistent issues disable location services as a test? I can do it but my crashes are infrequent enough I'm not sure how long I would have to wait for failure.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
I disabled location services and my device hasn't restarted since. It would consistently restart once an hour.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
Yes, disabling all location services does seem to get rid of the crashes, at least it did here.

Unfortunately turning these services off makes for a pretty poor device experience. No Google Now, no weather widgets, some browser slowness and lots of ad network failure messages in the logs. I would only switch these services off if you have no other choice or are interested in seeing if it solves your non HD Widgets soft reboot.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
No arguments here. I was just wondering if it is a real fix or more straw grasping. On the bug report page some are fixed on multiuser accounts doing it.....I never had that set up.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
We went through several logcat logs yesterday and saw the same behavior across different devices, some with HD Widgets, some without. The soft reboot of the system happens pretty much identically across all of them, and each time it appears to be the Android Location Services framework that fails. So while we can't say definitively that this is the only issue, there are very strong indicators that for many folks, location services is the cause.

Now if we can just get Google to assign someone to fix it... you know, since it impacts everyone on every device running 4.2.x
[Nexus 10 Q&A, Help & Troubleshooting] BobMiles:
I think Google is already aware of the problem, since the hd widgets people called it a confirmed Google bug.

However, Google probably tries to avoid bad publicity by admitting this major 4.2 bug and is working on a fix behind it's doors...

At least that's what I hope!

disabling location services appears to have reduced the number of reboots on my N10. I can definitely live without location services on a tablet :)

On my gnex, now that's another story.

[Nexus 10 Q&A, Help & Troubleshooting] ShadowVlican:
Still no crashes

I don't use HD widgets and I don't have Facebook installed
[Nexus 10 Q&A, Help & Troubleshooting] multimolti:
Can Facebook really be the reason? Or any app? An operating system used as widely as Android should be stable enough not to allow apps to do stuff like crashing the system... I thought all those apps are running in some kind of "sandbox" mode and have only the possibility to change certain features of the OS, as requested when installing the app.
[Nexus 10 Q&A, Help & Troubleshooting] AztlanUnderground:
One week and not a single crash even with currents auto updating, location services on or using Chrome.

I'm not using facebook tho'.
[Nexus 10 Q&A, Help & Troubleshooting] sdmark:
I had a few random resets. I did a factory reset and haven't had a reset since (5 days). Maybe something happened with the OTA?
[Nexus 10 Q&A, Help & Troubleshooting] ShadowVlican:
yea.. a factory reset and reinstalling my apps (without facebook, never used HD widgets) left me with a non-crashing nexus 10
[Nexus 10 Q&A, Help & Troubleshooting] razorblade79:
I've had reboots and lockups (touch doesn't work anymore, after turning the screen off, it doesn't turn on again) almost every day since I got it.

No HD Widgets, not Facebook (facebook messenger though)

I'll try disabling location services and see if it's really just the 4.2 bug since that would mean the tablet itself is fine.

So far I'm somewhat disappointed though that something like this would happen with the google premium tablet.
[Nexus 10 Q&A, Help & Troubleshooting] reubot:
OTA Bug Fixed

Just a note for those who flashed with the factory ROM from the website - you will need to reapply it as there was a bug that caused OTA updates to fail.
[Nexus 10 Q&A, Help & Troubleshooting] californiarailroader:
If you have to disable functions and uninstall software though, what's the point of having the device? I mean, you should be able to use it as intended, and do what you need and want it to, no? I hope Google fixes these issues quickly, this is Google's premier tablet after all, and with Samsung's name on the device I am sure they don't want to tick off Samsung either.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Another reboot. I may be in the minority since I don't have multiple reboots per day. That being said it seems most of my issues stem from installing/updating and uninstalling apps. Maybe the NAND is bad? Dunno, grasping....
[Nexus 10 Q&A, Help & Troubleshooting] dberthia:
Mine has been noticeably more stable since disabling the location service. I think we have a winner here.
[Nexus 10 Q&A, Help & Troubleshooting] nyijedi:

[Nexus 10 Q&A, Help & Troubleshooting] multimolti:
Since I deleted Facebook, its better, only one crash so far and maybe just because the background process was still running (I didnt restart the device after deleting FB).

Has anyone tried the update yet? I'm going to install it now and hope that the issue will be fixed =)
[Nexus 10 Q&A, Help & Troubleshooting] johno86:

Anything that might have to do with it?
[Nexus 10 Q&A, Help & Troubleshooting] vittogn:
In my little (non technical) experience a system reboot is cause by hw failure or OS. If removing an app give benefit, it is likely that it was triggering an OS serious bug. It works but it is a workaround!

I'm a bit disappointed by Google and Samsung, wile waiting for my N10.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
So are we just the unlucky few or they didn't sell many tablets? I admit I am hypersensitive to the issue because of the disaster I had with the original transformer. I noticed the Google code page only has about 140+ comments. While I think this proves there are issues I wouldn't think those are overwhelming numbers.

PS...rebooted twice today.

Edit: 3 times... Last when I installed gmail update.

I've been running CM10 Official for about 5 hours now and no restarts. I have location enabled for everything and have beautiful widgets reinstalled.

[Nexus 10 Q&A, Help & Troubleshooting] nyijedi:
FWIW, I had regular crashes (i.e., 1-3x per day) when I first got the N10. I disabled Location Services and removed HD Widgets, and I've gotten zero crashes over the last 5 days or so. I really think it's Location Services related.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
For the sake of beating Google to the punch I went ahead and erased and restored today. I'll be damned if it didn't crash restoring apps while I had chrome open. Going to try it again with location services off.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
Running CM10 since last night and no crashes. I have location services enabled too. The devs for CM must have changed something or fixed it.

I'll be sticking with CM10 until AOSP+ also fixes the reboot issue; which is still there in that rom.

[Nexus 10 Q&A, Help & Troubleshooting] nyijedi:
So much for Location Services causing the problem. I went for almost a full week without any freezes or crashes. I just disabled Google+ and the tablet locked up and restarted while doing so. Oh well.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Yea someone had already posted on the bug report page it wasn't the fix all. However, I did just make it through my app restore after disabling it without a crash. First time for that. Anyone call them? Is it even worth it?
[Nexus 10 Q&A, Help & Troubleshooting] xda6969:
I am using Beautiful Widgets which also uses the Location service. I don't get crashes and reboots. I think the HD Widget guys are not willing to admit their app is the problem.
[Nexus 10 Q&A, Help & Troubleshooting] nyijedi:
Their app is not "the" problem. Perhaps it's contributing to an underlying problem in the OS, but it's not "the" problem. I don't have HD Widgets installed and am still getting resets/freezes.
[Nexus 10 Q&A, Help & Troubleshooting] rxnelson:
Same.
[Nexus 10 Q&A, Help & Troubleshooting] eander315:
I have experienced a couple of random reboots, but I've noticed that they are much more likely when the processor is hot. After playing several levels of Osmosis I noticed the back of the tablet was becoming fairly warm and shortly after it rebooted. After it rebooted my cpu temp widget showed 36.8C. I don't know if this is related to the other reboot problems but it could be a contributing factor.

Having same issue. Location services off and no hd widgets
[Nexus 10 Q&A, Help & Troubleshooting] NoobieExtraordinare:
Same ****ing issues and

I believe its a hardware one, probably poor QC/QA in a batch of them. I have put in for an RMA. I:rolleyes: have had every combination listed here. Random freezes, Screen goes blank, soft resets. Power button unresponsive to wake up device, Device will boot instead of wake. Tried Factor image, CM 10.1 nightly and an AOSP custom with Ktoonez kernel. The latter two reduced reboots, but the device will still go into sleep and not wake up. Sometime it would but after like 2 mins. Also had the device shut off while fully charged. battery stats wouldn't report right. I have had it with this garbage. IF my RMA replacement does this too, this POS is going on Ebay.
[Nexus 10 Q&A, Help & Troubleshooting] mstroud:
Just a friendly reminder, folks, that the issues being seen here are not hardware related.

At our office we have a number of devices that all worked just fine with Android 4.0 and 4.1, and the moment 4.2 was installed they have all started behaving in the same way: seemingly random reboots and lock-ups. This includes Nexus 7, Galaxy Nexus and Nexus 10 devices. On the N7 and GalNexus, rolling them back to a 4.1 OS solves the issue. Unfortunately no such option exists for the N10.

If you feel that you want to RMA your Nexus 10, by all means do so. But please don't think that the issue will magically fixed when you get a new version because the problems listed in this thread are all software related. What is needed is a new OS update from Google, and until that arrives these problems will continue to happen.
[Nexus 10 Q&A, Help & Troubleshooting] johno86:
One thing that helped me reduce the amount of reboots was to change the cpu governor to performance. Whatever it is, it's still unsolved and still haven't heard anything from Google identifying the problem....
[Nexus 10 Q&A, Help & Troubleshooting] irishrally:
That's one theory, one that your supporting evidence certainly does not definitively prove. I have all three Nexus devices all running 4.2.1 and have experienced none of these problems at all, not even once. Now, I don't think everyone with an unstable device has hardware issues, mostly people don't know how to trouble shoot issues after upgrading the OS, or do not update in such a way to minimize issues. If someone completely wipes the device, flashes the factory image, -w update, installs no apps, and the device is unstable and constantly rebooting, then I would lean towards some sort of hardware difference.
