I flashed the 4.2 update zip through twrp recovery and since I've been having random reboots (watching youtube, playing a game, reading a forum, or just doing nothing).
Is anyone else experiencing something similar?

Same here. I had a random reboot while just sitting at the homescreen. Never had that happen before in two months of owning it. N7 has been my most stable Android yet until 4.2...

I just had mine reboot while it was sitting unused on my desk. I saw a flash and looked up and the boot animation was going. I hadn't touched it in at least an hour or two.
Never saw that behavior before 4.2.
Edit: Sorry forgot to add I'm stock. Not unlocked or rooted, stock OTA updates only.

Had the same thing after doing an OTA update (stock). Right after the update everything worked fine. It started to get bad a few hours after I added a second user (just for the fun of it). I had terrible lag and sometimes the N7 just rebooted Today I did a factory reset and now (at least at the moment) everything is fine. N7 has also been my most stable Android, and 4.2 was the first time ever I had to do a factory reset (note that I also have the Transformer Prime which was very unstable and laggy until 4.1 !)
I experienced the same issue, a couple of random reboot since last evening 4.2 update never had before... very annoying

So I did a factory reset and now Play Store keeps giving me an error saying "Update could not be downloaded due to an error" whenever I try to update the system apps, and a similar error when I try to download a new app.
The connection is working, I tested it by browsing with Chrome and by browsing the store itself.
Weird stuff.
update:
I solved the playstore issue by deleting and re-adding my google account.
Random reboot here also. The one that I know of just happened while sitting here at my desk. Noticed the Nexus 'X' boot logo on the screen. Battery life blows now, too.
Did the OTA update to 4.2 the first night it was available. Never unlocked or rooted.
I had one when YouTube was buffering a video
Stock 4.2 . unrooted. I can confirm the random reboots since i upgraded to 4.2
Happened in YouTube and whilst playing Jelly Defense...
Just got one too. Just woke it up and started Google Reader and instantly got the boot screen. Stock OTA, unlocked & rooted.

I'm unlocked, rooted and stock 4.2. I had something similar, I was using my nexus and had 49% battery life when suddenly my battery icon changed to a red exclamation sign !. Then it gave me the message to connect to a charger otherwise the tablet was going to shut-off. Seems weird since I had 49% battery life and almost 10 minutes later gave me that message and power off. Anyone experienced this before?
Yes; random reboots now that the OTA update is more than 24 hours old. Stock OTA, locked and unrooted.
I did a factory reset and it seems that since (about 24h ago), the reboots have stopped.
I'll keep you informed.

stock 4. OTA unrooted and then factory reset to properly set up multi users.
Now the device often does not wake from sleep.
It needs to be hard rebooted by keeping the power button long pressed.
Had my first random reboot last night on 4.2
Stock ROM, rooted, no cwm.

I do believe all these random reboot caused by the apps that are not up to date with 4.2. I have been keep recieving many updates from play store recentely (I just got 12 apps for update when I check the play store).
so I believe if wait for several days and let's all app developers catch up with 4.2 and push the updates the tablet, I have feeling these random reboot disappear.

I believe this is a likely scenario. I'm getting the same kinds of random reboots on my GNex, which was updated to 4.2 at the same time as my N7.
So far 1 random reboot this morning, sitting on my desk doing nothing, looked up saw the boot animation. Hopefully everyone is right about the apps, and that it will be fixed with app updates. It would be nice if there was a way to quickly identify all apps with an issue on 4.2... (on device app that scans it...)
Hello everybody,
I have been waiting a bit until posting this issue to see if future nightly builds of Cyanogenmod solved the problem but to no avail, I already posted on their forums but so far no one has been able to figure out the problem... not that they tried.
I'm using an international Galaxy note (n7000) and these issues have been popping up since last month.
The main problem comes up when using the android keyboard and listening to music at the same time, the phone just seem to struggle a lot, music begins to stutter and usually the phone just becomes unresponsive and I have to force reboot the whole thing. A pain in the neck. Lately the phone just hangs whenever it feels like it and I have to reboot it, it usually happens twice a day.
Sometimes you're able to come back to normal after a few minutes but rarely.
The problem was even worse while using SwiftKey, now I'm back to just using the normal android keyboard but still the issue pops up almost every day. I already did a wipe data/factory reset, no avail.
Any thoughts on this?
Thank you in advance.
Post a log. Which ROM where you on before flashing CM.
sounds like a memory leak, try newer versions or trace down the issue. Check which apps consume most and cpu when it occurs.
Check as previous poster said logfiles

CM 10.1.3-N7000 bluetooth issues
Hello,
I'm using CM 10.1.3-N7000 and I really love it, but I'm forced to use another ROM, just because of the carkit compatibility via bluetooth. The sound is extremely bad.
Does anyone know if it's fixed in later versions or earlier versions?
Are there other ROM's, ot based on CM without the bluetooth problem?
I'm really searching since two days now to find a bluetoothfix, but can't find it.
Pairing and so on is no problem at all, it's just the soundquality that is terrible. (it was not the case with my stockROM)
thank you for giving me some advice!
I switched to Omnirom and I think the problem has been solved now.
If I see that the same problem is back as it was with CM, I will come back to that.
Hello guys,
I got my tablet some month ago, it's the m5c5 model. I immediately flashed mirek roms 7 on it, and it ran fine for a week.
Since then, it crashes a few times a day. It is extremely annoying! It doesn't matter what app I'm running, it just crashed randomly. The screen looks like this
I can't post outside links, as I'm a new user so put h before it : ttp://i.imgur.com/qfDQAB3.jpg
I assumed it had to do with mirek's rom, so I installed his previous version, his ultralight version, still happened a few times a day.
So I flashed the debloated stock rom, and it still happens!!!
Can someone please, please help me!
It is extremely frustrating
Thank you in advance
Hi rekopel,
I'm also experiencing the same problem with the same model of X98. Have you managed to solve this problem in any way or you prefered stop using this tablet?
My problems do not occur so frequently but from time to time it happens to crash. At least once per day if I use it more. This happens during usage of simple everyday apps not games. I don't play them, so I don't know what would happen in that particular case.
If anyone has any solution to this I would be very glad. I'm still using stock rom. I'm thinking on firmware flashing, but I'm not sure that would solve my problem.
Thanks in advance.
I recently updated my stock firmware with Google Now and tablet works much better now. However random freezes still occur almost every day at least once, sometimes even more. It's very frustrating making this tablet almost useless. When buying this tablet I read almost only positive reviews about it, but it seems it's no more than Chinese scrap.
According to high popularity of this tablet at it's launch I would suppose these tablets are still in use, as we don't buy them for only a year or less. But with this model I might be wrong.
So, if anyone has any solution I would much appreciate it
Hi everybody,
I also experience the same problem. My tablet model is C5J6. It happens both in Windows and Android, more often in Android.
I've suspected it has some bad memory block, and when the applications access it - crashes. But I run standard memory test in Windows, and it passed without any problems.
If anyone find something, please share.
Thanks.
Hey guys,
This may seem like an odd scenario but I bought my tablet months ago to game on it specifically for Clash Of Clans. Everything worked well up until this morning. I was making breakfast and realized that there was an optional update so I performed the update. I then accidentally dropped my tablet in the kitchen which landed on my kitchen mat (it also has a case). When I sat down and launched the newly updated game I am experiencing incredible game lag. Almost like the game is performing at 10 fps. I looked at Game Tuner and made sure everything was turned all the way up. I restarted the device multiple times, uninstalled Clash and reinstalled it three times. More reboots etc.. I even installed an earlier version of the game but I am still experiencing the choppyness.
Does anyone have any ideas on what I can do next? Did my drop in the kitchen cause the tablet to under-perform and possibly break or is this merely a software issue with the update? Can I force the game to go into some high performance mode? Definitely not how I wanted to start my morning!
Thanks in advance.

It appears that the issue was stemming from a low battery (around 35%). I came home to a fully charged system and there is no lag.
As long as it didn't crack, you should be fine.
You're right about the battery, I believe the processor begins throttling down at low battery
That's a Marshmallow battery saving feature. When you get to about 40% it starts turning off cores. Perfectly normal! My phone becomes noticeably slower when power dips. It's a bit annoying.
I think this also happens in lollipop (5.0.2) as well. Mostly around 35%...
Hi,
first of all sorry for my bad english and screenshots with german text .
The situation:
I have a total of two Tab S2 (T-813). The first is 4 years old, the second is less than 2 years old. The newer is now causing problems.
The reboots occur:
- When using the tablet. Definitely with a high load, but also sometimes with only light loads
- When it is charging
- completely random
Edit1: reboots are not related to the battery percentage
Edit2: never experienced a reboot while in TWRP.
I didn't really find anyone with the same problem on the Internet. It is not a boot loop. Sometimes you can use the tablet for hours/ days. Then again not at all, because it starts again after a minute. To narrow down the problem, I formatted both tablets and installed the same lineage version and firmware. Since it restarts, log files are unusable, right?
Is there any way to narrow down the error?
I suspect overheating, but I would like to know if I have any way to isolate the fault exactly. Maybe there is also another (hardware) forum, which can help better in this case, then I would also be grateful for a tip.
I would have no problem opening the tablet. I've already done this with my smartphones.
Thx for your time.
Solution:
It is an overheating problem if you have exactly the same problems as I had.
You can test it simply like this: fill a plastic bag with cold water and some icecubes. Use it like a pillow for your tablet so it can rest on the bag while you use it. I had no problems at all while doing this.
I send it to Samsung and they repaired it.
It's just as new now.
I actually have the same problem, just only when its at 15 or less battery
Hi.
Well, it sounds for me like a different problem, cause it's battery related. My battery is fine and I have reboots not related to battery status.
Have you tried anything (factory reset, newest lineage and firmware,...)?
Hi,
same here. A SM-T813 running LineageOS that started with random freezes and reboots about a week ago. Sometimes I can use it for about half an hour without problems, next time it reboots while rebooting ...
Seems to be completly random, only thing I noticed that it never reboots while in TWRP.
Cleared and reinstalled LineageOS, but didn't change anything. First time rebooted while still in the setup wizard, next time I could finish the wizard and install serveral apps before the next reboot.
Maybe a problem with the memory?
Yes, that is exactly the same.
I never experienced a reboot in TWRP. No problem with reinstalling lineage.
But while reinstalling Android, it reboots while configuring and while reinstalling apps.
The last days I could watch Amazon prime every evening. Now it reboots after a minute even without using it. I shut it off and hope it will work this evening again.
I have the same issue, sent it in for repair asked to flip battery and swap mainboard. Got it back. Worked a few days, then had random reboots again. I am 100% sure it is a battery issue, and when you get under a specific voltage, maybe when it gets under 30% or so, the chance for reboots rise dramatically, with high cpu or flash memory usage. It happens more often when doing a update in Google Play store for example. So totally have no idea, if Samsung flipped the battery or not, but this was my last Samsung product ever. I would assume there is an issue with too much current drain and then it reboots, and the battery used in them are not designed for the units properly.
same to me. i was on stock rom. never root or anything. and got random reboots most of them when i open google play or google chrome. now im on lineage and same. also i notice that the tablet didnt reboot until i install gapps. and the tablet never reboot on recovery or TWSR. reboots on high or low battery. and if it was overheating maybe the tablet will reboot on recovery. dont know its weird. i will try lineage with out gapps to see what happend.
just testing lineage without gapps no reboot. run browser and netflix with no problems. then i install youtube from aptoid store. and reboot start again. o unistall youtube and no reboot for now.
Same here. I have random reboots but also wifi disconnections (unable to reconnect until i reboot the device)...
Not evident cause...
Someone got a solution for this?
Have the same problem on my T813
You can find the solution for the problem I described at the end of the first post.
