[Q] Random reboots since 4.2.2 update - Nexus 7 Q&A, Help & Troubleshooting

I don't remember having a problem with my Nexus 7 and random reboots before the 4.2.2 update but ever since the update, I notice that it reboots spontaneously several times a day. I'm rooted with the stock ROM.
Anybody else having this issue since the update?

Yes, I also have problems with the Google play music but the reboots are not frequent but still.

No, not many people are reporting this. What kernel are you running? Spontaneous reboots make me think kernel issues.

Kernel version 3.1.10-g05b777c

*777c is the stock kernel for 4.2.2 and been running that for 10 days or so, and no - I haven't seen or notice any random reboot - on stock rom.
Do you have any background APPS or widget running that might be doing this ??

I have Weatherbug widget and a battery widget running, I'll have to check those, although they hadn't caused any issues before the update.

Random Reboot 2.3.4 i9020A

Hi,
I'm starting to have random reboots since the new update 2.3.4. Anyone else having problems ?
- I have the Fido Nexus S (i9020A)
- CWM 3.0.2.5 for i9023 (as specified in the thread to root)
- Rooted
It was ok (some reboots during calls, but not when the phone is just sitting there like it does now) with 2.3.3
Thanks in advance
Mine rebooted 3 times today.
First time I've seen it happen on 2.3.4 and it's aggravating.
It happened on my 2.3.1 and 2.3.2
I'm i9020xxkd1
I have not seen it on mine as of yet, I have just rooted and installed CWR so I will see if it changes and let you know.
What I had done before upgrading was to flash back to complete stock 2.3.3 then perform the upgrade to 2.3.4
No random reboots on mine so far. My phone is stock, unrooted.
Mine has worked great also but it is stock, also unrooted.

I haven't had any reboots with v2.3.3 or now with v2.3.4 using a Rogers Nexus S model 9020a. I'm running stock and not rooted.
Maybe rooting causes this issue as the only posts with issues are all rooted?
I've been running mine rooted for a day, used it pretty heavily with no issues. I did have a reboot loop in 2.3.3 but that was with Beautiful Widgets.
So far no reboots while in call with 2.3.4 (knock on wood), as it was bad with 2.3.3. Manually installed 2.3.4 within a few days after its release, and have had a few disconnected (dropped) calls - but not a full reboot of the phone itself.
One might say this is T-Mobile, but in the 9 years I've been with T-Mobile, I've never had a problem with dropped calls before. So I can't help but wonder if this is a 2.3.4 issue, since it didn't happen before 2.3.4.
While annoying, at least it's not as bad as a full phone reboot.

Yep I'm comming with the same conclusion. It's pretty lame since there's no way I'm going back to unrooted, guess I'll have to deal with it until someone finds what program is causing this.
I'm getting about 2-3 reboots an hour, this is getting serious. Any way to obtain the crash log or something to tell me what's causing this? I've read logcat wasn't really reliable.

Seems to have something to do with the SETCPU app. I'll try changing some of my profiles. When my phone is full charged, I don't have any problem, but as soon as it gets kinda low, I can have 4-5 reboots an hour or 0... all comes down to luck.

Random reboot

I'm still on my stock ROM with just root permissions and I'm getting random reboots every once in a while. Before I was rooted I had one or maybe random reboots that I remember and one of the times it just reboot while it was in my pocket. I rooted my phone two days ago and since then my phone has randomly rebooted itself about 4 times already. I had the two mods added which were the touch screen and video bitrate mod. After I seen it happen more than usual after adding those mods I reverted back to stock. I was wondering if anyone else is having these types of issues maybe perhaps a bug in the stock 4.2.1.

might be a widget. a lot of people are having luck with the franko kernel. but his r16 build released earlier today started giving people random reboots. he either has it fixed already or is in the middle of doing so. the r15 build that i am on is great. but i would wait for the 16. the changelog looked pretty good.

wouldn't hurt to wipe anyway. ill stop wiping and see if i notice a difference though, so far i dont notice any. so id probably just skip out on wiping as it does seem useless because my phone still feels the same

If it works, it should work ok with CM as long as you run it in TWRP.
It doesn't actually touch the ROM. It uses the kernel to reset the DDR3 memory timings and allows the system to retrain.
Thanks, I like to know what I'm flashing. Just flashed, will report back.

Edit also was on slim bean flo and had same issues so it's something messed up in the rom i would assume and not the software version it self

[Q] freezes on 4.4.2 custom roms / kernels

on the latest d802 4.4.2 custom roms and kernels i get a lot of freezes.
it will freeze in the middle of an animation and will take some seconds up to some minutes and then working normal again.
sometimes i have to hard-reboot to get out of freeze / lag.
on older 4.4.2 slimroms i never had this behavior, only since some weeks with new roms / kernels.
i`ve tried every rom / kernel combo but sooner or later i will get a freeze again.
could a revert to stock and re-rooting / flashing custom rom maybe a solution? i`m afraid to do this because of the long time to backup my 32gb data.
what are your experiences with the latest 4.4.2 roms and kernels? did you find a solution for this with any combo or fixes?
help would be appreciated.
push! no one else with same problems? maybe i got a hardware defect?

The only thing I can say is I own the VS980 version of the device and i've tried every single 4.4 rom offered on this sight and have the same issue with all. Most of the time i'm using the device and it freezes, sometimes reboots, and sometimes comes out of it after a few minutes. Also not being able to wake the device only seeing a black screen and forced to hard reboot device. 4.3 seems to be a much better with these issues but not completely solved for me. I'm hoping the release of 4.4 source from lg will fix these issues but i'm unsure. So at least your not alone in these problems lol. I've tried multiple kernels and governors etc. Bumping up the min freq on the cpu seems to help and changing to interactive governor but doesn't eliminate the issue just help. I thought my next move would be to use lg flash tool and update to latest firmware reroot and install cwm.

i think i will do the same today after work. hopefully this helps.
the better option would be to stay some days on stock rom to ensure there is no hardware defect. but i can`t stand stock so this would be a hard route! ^_^

Yea unfortunately it seems very common among these devices so i'm pretty confident it's a software issue although i'm not 100% sure of that. I ran a flex rom for a few days on 4.2.2 and didn't have any of the same issues.
added a poll as a matter of interest.
omni-ROM, Mokee rom, vanir rom etc.freezing problem still continues.
Using CM11 (4.4.2) for 5 days with zero freezes so far.. note that this is on D800, not 802.

Yes, stock cm kernel.
I'm thinking back now and it did freeze once when first signing into the Google account immediately after flashing the ROM, but nothing after that. So.. nearly spotless
Nice! Maybe they are getting the issues ironed out. Haven't been on cm11 for a week or so since it was the worst with freezes for me. I'll have to give it another shot.

Best of luck! To be specific, I'm using the snapshot release of cm11... still don't trust the nightly releases
i did a lg flash tool stock restore, factory reset and OTA updates. now the freezes did not come back until now *knock on wood*.
when i did a backup of the sd there was one corrupt media file which was not able to transfer.
maybe the media scanner did go crazy and was the reason for the freezes.
using cm11 m3 on my d802... very little freezes compared to previous nightlies, fingers crossed

[Q] Android 4.4.3/4.4.4 bug - Backing out of apps, opens recent application

When I flashed stock 4.4.3 update (kernel, radio and firmware) I thought maybe I've installed a bad ROM.
Every time I backed out of certain applications, the last application in the recent apps list (the one before the one I just backed out from) opened for a second and closed it self.
For example, I played Boom beach, sent it to background using HOME.
Then, I used App Stats, played around in some screens and then backed out of it -> Boom beach opened for a second and closed itself.
Then I installed the 4.4.4 update, and this still occurs...
This doesn't happen with every application... I can back out of most apps without any issue.
This never happened on 4.4.2 and lower.
It may be an app issue and not the system so I'd love a feedback from you guys before I contact the apps developers.
Am I the only one who experience this issue?

You suggest a factory reset through settings will do the trick?

I factory resetted in TWRP then Fastboot erased leaving no trace behind, and then fastboot flashed 4.4.3. It's stock.
It's probably not well known because people may be using their device differently, pressing Home to exit an app instead of using Back maybe... or they don't think much of it to report it, I know I didn't, but it does get annoying after a while.

Well, I don't have this bug. I just opened CSR Racing, pressed Home to minimize it, then I opened eBay application, then I pressed Back, and it went normally to home screen, CSR Racing did not appear.
EDIT: I managed to reproduce it. CSR Racing appeared for a second when I exited from Settings. I never noticed this until I read this topic. So, bug exists.

I'm sorry to ruin your LOLness but it may be a kernel/ROM related issue. I already found a 4.4.3 ROM (LiquidSmooth 3.0, didn't check 3.1) where this bug doesn't occur.
Moreover, the kernel is responsible for cleaning up the memory by killing and restarting applications.
I created a small application that behaves like a taskiller (restartPackage/killBackgroundProcesses) and kills every app I exit, just for testing purposes and it didn't work as expected on 4.4.3/4.4.4 so I think it's probably a kernel issue (4.4.3 received an updated kernel which is used on 4.4.4 as well).
It can still be a systemUI issue but even if it is, that can be fixed on AOSP ROMs, without waiting for Google.
If you have a link to the reported bug ("known bug"?) that would be great.
Edit. Bug persists with CM11
