[Q] Strange screen issue with reboots

Hi.
I'm new to Nexus 7 and after a short time using it I began experiencing some strange issue with the it. While surfing the web over WiFi (note that I'm using the first Nexus 7 with WiFi only) after a short time glitching lines appear on the screen (as shown on the image attached) and some loud white noise coming from the speaker. It's stuck like this for about 30 seconds and then reboots. After reboot, everything seems normal, till it comes again. It takes 15-30 minutes of surfing and I believe the time depends on the intensity of surfing. Seems like WiFi modem somehow affects the GFX driver.
Note that I was first running android 4.1.1 and recently updated to 4.2. Updated didn't fix the problem. I've rooted the device with "Nexus 7 root toolkit v.1.5". Note sure if the rooting affected it somehow, as I rooted the device on second or third day of use.
Anyone have an idea of what could be wrong or how I might fix it? Or it's HW issue and I should turn it to Google?
Thanks!

So I'm the first and only one with such problem???:silly:

I could be wrong here but that seems like more of a hardware(warranty) kind of issue. However, I had the speaker issue after flashing a custom ROM (sparks linario 4.2.1) and I had the speaker issue (along with a host of other bugs buts that's beside the point). I flashed stock and unrooted and the problem was fixed... I know it might not help your case but I thought ide let you know. Its possible the toolkit caused the issues and flashing back to stock and rooting with another method may solve your issue (that's what I would try). But if you end up sending it in under warranty for god sakes, unroot and relock your bootloader first! Otherwise Google probably won't honor your warranty.
Good luck friend.

Phone Process closing immediately after opening on ShenduOS

Hey guys, I recently installed [7.18.13][4.1.2][v1.0] ShenDu OS,
and everything works fine aside from getting the message "video recording failed" on snapchat.
But the real issue that I care about is the phone process immediately closes after launching.
So I can't or even receive a call at the moment. Anyone else having this problem?
I've reinstalled a couple of times now. I really like the look of this rom, and
it runs smoothly. It's just, you know, I'd like to call people sometimes.
Thanks

That's a bug with ShenduOS rom port.
I know that ROM is amazing but 2 others have also reported phone fc
It might be because the kernel is missing a few files in the ramdisk since i remember coderzs saying that the .61 cannot be used with cyanogenmod .

Nexus 7 2013 random freezing

Hi guys i got some freezing issues, anyone got an idea what could it be? i'm totally new to Android/tablets, so other then this info, i don't know what else to say, or explain the issue better, it just freezing for like 5 sec, and after it works normal, its random freezing. I hope anyone can help me, thanks.

Is it when you update or install apps?
This is normal, the OS can freeze for a few seconds during write operations.

What ROM and kernel are you using? Are you over clocked?

No overclock at all, Kernel - 3.4.0-g9e52a21
Build number JSS15R all stock here. No custom ROM's..

I experience the same BS on an all stock WIFI model (2013.06 date code). Thought it was JB 4.3 teething pain but my Note 3 running 4.3 doesn't do it. Have mainly noticed it playing Great Big War Game where it'll randomly freeze the whole tablet once per launch for about 10 secs where nothing responds (show touch, home, switch task, etc.) then it'll either return to normal or prompt with dialog to wait or close. Have also had it happen in Modern Combat 3 along with the random app close that, again, doesn't affect Note 3. Haven't seen newer apps affected so perhaps it's a software issue and is fixable but it's irritating nevertheless considering it's a Nexus device and after correcting the touch issues with ts10 firmware update. Going to try reflashing the stock image to see if it fixes it otherwise looking forward to dumping this Asus for a Note 10.1 2014 LTE. My Note 10.1 2013 and Note 2 have been 100% solid with never a crash, hang or touch issues.

I had freezing problems when i was trying out the TS20 fix. TS10 seems to yield erratic behaviour randomly after each reboot.
Ever snce i've been testing the ones between TS10 and TS20. TS16 works better for me than TS18 - just being more responsive but both has no reboot issues. Am testing TS14 now and it seems better than TS16 but i needed more time to run it. None of the 14,16 and 18 has given me any kind of freeze after 24hrs of testing on multi-touch intensive apps.
You might wanna give 16 a try... i will be posting a more detailed update in sfhub's thread when i'm done with TS14 and TS12 testing.
Cheers

Thanks for the answers guys, but this is really new to me, i got no idea what is TS 14, TS 18 or TS16, can you guys explain me a bit? thanks.

I had the same issue. Please see my observations at post: http://forum.xda-developers.com/showthread.php?p=46082214#post46082214
However, I have recently tried to uninstall all apps (backing up with titanium backup) and installing back in bunches. With only the apps/games I use daily, the issue appears to have subsided, and I am trying to slowly bring apps back to see what the issue is.
Original post for consolidation purposes:
When it happens: Touch intensive Games (drastic, MMOJ, Dumb Ways) appears to be when the 3D GPU is NOT in use, netflix, when paused for a short while.
What happens:
1. Screen does not update display appears frozen
2. No response from nav bar icons
3. Power, volume buttons give no response.
4. If audio was playing right before it froze, it will keep playing as if nothing wrong.
5. If I hit the power button or the nav button then let it sit for a few minutes, suddenly it will react to every press I did in quick motion and go back to normal.
5a. I had show touches enabled, which showed a random number of the frozen touches working in quick succession when it "unfroze"
6. Sometimes requires a hard restart with no response.
When it started: Right before the Q update starting rolling out, did not have issues out of the box.
Purchase date and location: Right around the time of launch from best buy, 32 GB 2013 version
Troubleshooting steps: Safe mode (doesn't appear as often), full factory restore to the Q image when the R image started rolling out. Issues were gone for a short timeframe, then returned
Config information: Stock, latest firmware version, rooted via TWRP (latest version installed), and SU.
Observation: Appears to occur in select situations, and I believe I always have a GMAIL notification right when it un-freezes.
Let me know what you think and if it should be merged with a different topic, didn't see anything about it un-freezing when it was frozen or audio still playing.

Please refer to this thread for a fix:
http://forum.xda-developers.com/showthread.php?t=2428133
The fix from the thread above helps with many touchscreen issues including freezes.
At least it helped with mine. I was experiencing freezes and so called "sticky touches" (like when you short tap on something and the device interprets it as a tap and hold).

My device came with pre-Q and went through three OTA updates. After reflashing with factory R image minus wiping data (remove -w from flash-all.bat file) and with ts10 all appear to be better so far. Modern Combat 3 still randomly closes but it could be Gameloft's crappy coding. Need to run it for a few more days to confirm but reflashing factory R image with ts10 offer the best experience so far.

Mine does too now in addition to the already random reboot. The freezing happens when I try to input text on the keyboard.

Skype & Kitkat issue

Everything was perfect when i was on Android 4.3, any skype calls working, video/audio doesn't matter.
But when i updated my wife's phone to kitkat, some skype calls making phone reboot(black screen, then its loading as usual).
It happens not always. And i have noticed that it crashes only while talking to people who have Windows XP installed(with latest version of skype, checked & updated myself).
When she talks to anyone on 7&8 Windows - everything is perfect.
I have tried all custom roms, original, rooted\not rooted, anything.
I gonna write this issue to Skype too.
Skype support asked that Skype not supporting KitKat yet.
Btw it only happens on Nexus 4, when i'm on my phone (XT910) on KitKat, it works and not hangs.

In my case occurs the same...I believe is maybe kit Kat by itself and usually happens when I leave a call in the background while I use another application. Unfortunately I haven't found any solution for that.

i have noticed that it crashes only while talking to people who have Windows XP installed(with latest version of skype, checked & updated myself).

Not really. The problem is a bit more serious: all ROMs (stock and custom) based on 4.3 or 4.4 are affected by this overly annoying camera bug. I obviously hope you're not, but if you end up as unlucky as I did, your camera and LED flash will soon become totally unusable (on all applications), fixable only by reverting to 4.2 or updating to L (I did and it's totally worth it)
Good luck :good:

Also another issue with Skype and N4 is that whrn listening to music and an image is being sent / received in the Skype chat window, fetching that image from the gallery/disk causes the audio system to crash. It's really annoying. Probably it's the same issue as the well-known audio stutters on changing connectivity and high cpu load.

Im using the Verizon G2 and running 4.4 2...xdabebb rom..i use skype a lot for business calls and havent come across this issue at all. On unrooted stock as well as custom. Ive also faced no issues on an S4 i9500...so it might not really be a kit kat issue but a nexus 4 specific...or an aosp based rom specific issue

I have another kind of issue with my xiaomi Mi2 with MIUI Rom on kitkat 4.4.4. I have systematically a black screen when the communication is established on Skype also using test sound server. The sound is working but I can't do nothing with the phone until the end of communication decided by my correspondant.. Very annoying . I have post the question to Skype 5 days ago but no answer. Skype was working properly on my phone on miuiv5 android 4.1.2
Envoyé depuis mon Mi2 kitkat 4.4.4 Miui6

I'm having the exact same problem ... I was talking on Skype video call and the phone screen went black and I couldn't hear the other party.. I don't if they were able to hear me or not. I had to hold the power button and reboot my phone manually. I don't know what the problem is but its very annoying and it happened three times in a row. I have used multiple ROMs and it was happening on all of them and they were all 4.4.4. I don't flash kernels, I just use the kernels that come with ROM because they have obviously been tested and have been found compatible with the rom. So I know its not because of kernels. Currently I'm on Slimkat latest weekly and was thinking about going back to stock but someone said its also happening on stock ROM. I'm going to try CM11 and see if it happens there as well. Will report back soon. Hopefully it's just a 4.4.4 issue and not a phone issue.

Nexus 6P crashing all the time

Hi guys.
I'm here to share a problem I'm having with my Nexus 6P: it often gives a crash randomly, needing to be restarted by force.
This does not happen because of a specific app and sometimes happens even at boot , when Google logo still not appeared.
I already using the phone about two weeks.
I received him with rom stock 6.0.1 and had the upgrade to Nougat available.
I thought the upgrade to 7.0 would correct the problem, but it was not what happened.
From the update I also felt that the crashes were more frequent when the battery was at a very low level, between 20 and 15% (as commented in a reddit threat that I can't copy here).
Following some recommendations that I found , I formatted the Nexus 6P with the factory settings to see if the problem returned.
Yes, it happened again.
I formated again and was gradually installing my apps to check if it was not a specific app.
I did it at last three times.
On these occasions, apps like Google Keep, Duolingo, ES File Explorer, Google Fit, Podcast Republic and even the Play Store gave the crash.
I formatted again and installed each app one by one again to try to identify a culprit and had the same results.
To try to work around the problem, I decided to go for a clean install of the entire OS with the latest build using the SDK (adb and fastboot).
Even with the flash of the latest build I continued to have this crash problem.
So I decided to go for custom roms.
I installed Pure Nexus and Sinless, and continued having problems with crash.
I tried to install the CyanogenMod, but failed. After flashing the rom, GAPPS and vendor image, the device crash in the Google logo.
My last attempt was to go deeper and replace the kernel as well.
I installed ElementalX (7.0) and Pure Nexus as ROM.
In the beginning, I still had many crashes, so decided to make some changes in the kernel ElementalX.
In a desperate attempt, I decreased the CPU clock all to minimum (1248 MHz).
Interestingly the crashes started to occour less frequently, but they still happen randomly and unexpectedly.
I have no idea if this reduction in CPU speed had any effect or was placebo.
What matters is that I'm still having crashes and I wonder if anyone has any idea of this solution to my problem.
Thank you guys!
PS.: the return of the phone is not an option. I'm in Brazil.
PS2.: sorry for my bad english.

Wow you have exhausted every idea... Return sounds like all that's left unless you wanna try putting the phone in the oven to see if it's just bad solder.
