[Q] Random key presses after rooting - Acer Iconia A500

So my A500 had a problem with random keys registering. If on the home screen, apps in a certain region would launch randomly (using the stock launcher). If in apps, keys in a similar area would register on their own, initiating whatever the corresponding actions were. If watching a video, the screen would randomly resize during playback.
After having the system lock-up and needing to reload a stock HC 3.01 ROM, the key-presses stopped. After loading a rooted HC 3.21 again (which isn't the same root I had initially), I noticed the random keypresses started again. I'm now running stock again and no random keypresses for at least an hour. Played several videos while I searched for something similar on the boards.
So 2 different rooting processes produce random keypresses, and rolling back to stock twice gets rid of it. Has anyone seen this before? I'm considering re-rooting all the way up to ICS or JB, but I'd like to know if I should expect that behavior again.

Can you tell us what recovery you are running?

Can you tell us the recovery you are running? Personally I never had the issue but maybe someone can figure out what is going on if you tell us which recovery/rom is doing it.

The first time my recovery was jacked up and unusable, i guess i had the half-root but no unlocked bootloader so nothing would install. The second time was CWM as installed by Acer Recovery tool. It was the later version of CWM, don't remember the exact number. The initial half-root was months ago
If it helps, i used the rooted EUU the second time i rooted which started with TWRP and was updated to CWM after the fact. Being stock again, its on the stock recovery. I can look up the EUU filename once I get home tonight; it's on my home computer.
EDIT: Poked around a little cause I knew I got the 2nd root EUU here on XDA, here's the link for the process I followed over this past weekend:

I've encountered the same issue, but I also replaced my touch screen so I attributed it to something I did. It is extremely annoying. I've not tried to reset back to stock is or another rom. Maybe it's work a shot. I'm using the v8 unlocked bootloader and thors latest cwm.

[Q] Words with Friends Problem Acer A500

I have just bought Acer Iconia A500 and when I play Words WF the tray tiles keep shuffling until I place one, running Honeycomb 3.1, is this a problem with the tablet or software ? I have tried turning the rotation off any ideas please
I play the game myself on my tablet and do not have this problem.. Are you running the Tablet version of the app of the phone version? I have no issues at all witht he tablet version.
I expect the tablet version I downloaded from market with the tablet I did not need to specify so believe should be right I have got the ap on an Optus Tablet works fine, thanks for your reply ????????????
If you got it through the market as opposed to installing an APK manually then you should have the right version. I am at a loss as to why you are experiencing the problem you describe though. Not experiencing this issue at all myself.
try to uninstall, then reinstall, may be a bad apk u installed
Hi. Your accelerometer is what's causing the issue. It's reporting the Z axis to be 0 to + 18 instead of -9.6 to +9.6.
I have the exact same issue. It's not a bad install or APK. You'll have the same problems in games like ATilt 3D Labyrinth, and anything else that relies on Z-axis. Have been looking for a fix or an update that fixes this but so far nothing.
I've tried multiple roms so far. My next attempt is going to revert back to stock (unrooted) 3.0 and try the OTA updates.
Update: Just reverted back to stock rom, issue is present in words with friends and also ATilt 3D Labybrinth. However, it's not present in Labyrinth Lite. Odd. updating now to stock 3.1
Update: Just updated to stock 3.1 via OTA. Words with friends now working/not constantly changing tiles.
I had the same problem. Constant shuffling in WWF. Updated to 3.1 and seems to be gone. They should've put a way to turn off shake-to-shuffle (which is what causes the problem). Honestly who would shake their tablet (or phone) to shuffle when there is a button right there?
Hi thanks for your really detailed reply you obviously know your stuff but as I am very new to tablets I have no idea what or how to update etc. Tablet tells me 3.01, Kernel 2.6.36.3 and build 1.016.04.
What is rooted etc, sorry if I seem a bit thick but struggling with the terminology and process, I therefore probably am a bit thick....LOL thanks for your assistance, Phil

static lines/ glitching

Anyone else had any graphic glitching?
i was using inparisv4 i have been getting the odd little graphical glitch,
At first its just a small; a flash here and there, but recently the entire screen has be glitching for about 30 seconds at a time (Full on like a no signal telly)
Searched in the forum, and a few people had the prob when flashing the touchwiz interface. they solved it by flashing to samsung ota and then back again.
I tried that i thought it was fixed but a noticed small glitches just once.
Anybody know whats causing it?
I am really freaked
Screen Glitching
I had a new "re-furbed" tab that within the first 30min of use exhibited this. Then the screen went dark and it never booted again. I believe that this is hardware related, and from what I could tell from my research, it happens on stock as well as rooted tabs. I sent mine back to get another "new" one, and hope that I do not have this problem again as the tab is exactly what I was looking for.

Strange ICS bug

I flashed the stock ICS rom with CF root kernel the day they came out and everything went fine. However, there is something strange that happened to me twice so far. At random times and while the phone was locked (lockscreen) when I tried to unlock it and use it the screen goes crazy and it becomes blurry with numbers and lines and colors blending like crazy (reminds me of the matrix film with the numbers running down). This happened to me twice and only with the ICS rom and it goes away with a hard reset.
Has anyone else experienced this?
Hard reset?? on ICS?? if im not mistaken thats factory reset??
Switch Off

Switch Off CRT Animation, in custom rom it is built-in, no idea for stock though.
Yes. I've experienced this too. Just two times in about two weeks, nothing to worry about, though. Pressed the on/off button and the glitch went away. Seems to be a problem with the graphic driver. Or maybe just a Touchwiz launcher problem on ICS, don't really know.
I'm on a unrooted ICS (updated via Kies) Note.
G
Same thing happened to me once while browsing on the default browser and rotated screen from portrait to landscape : colored lines salad, not responding to middle button or touch buttons. After turning screen off then on everything was fine again.
Stock LPY rooted, flashed with Mobile Odin Pro.
Same happened to me. Default unrooted ICS, Kies-updated.
So it appears that this occurs whether someone has rooted their device or not. Hopefully Samsung will publish a stable ICS built to end this barrage of issues with the new Firmware experienced by many. It feels like we are Beta testers on this device.

[Q] Nexus 4 Freeze and Crash

Hi All,
I'm currently experiencing a problem, that I know has popped up on this forum a couple of times, but not for the Nexus 4 specifically.(As far as I know....)
The problem appears to be random freezes, where the device just stops, screen freezes, no hardware or software buttons respond, and requires the power button to be held down for a few seconds to restart... It happens once or twice a day, at random intervals, mainly when i'm at the home screen or just browsing Chrome (Beta).... My Nexus is running the latest Nightly of CyanogenMod 10.1, build 20130529, although this was happening on the RC1 build too... Also running the latest franco.kernel 3.4.0 and Clockwork Recovery. Haven't partitioned, restored any backups etc as of yet. I also have about 230 apps, so if it could be software related, there's i high chance one of those has got something to do with it!
A suggestion or solution that doesn't involve fiddling around with ROMs, kernels and other stuff would be great, i'm not much good at that sort of thing and don't allocate much time to fiddling about with my phone, but nevertheless if required i could give it a shot....
Thanks,

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.

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:

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.
