[Q] Touchpad "Touch" Stops working randomly - TouchPad Q&A, Help & Troubleshooting

Good Evening,
I have a 16GB Touchpad. I've run numerous roms on the system. I currently have Evervolv Nightly 8-17-14 4.4.4 (I think). I have had JCS and Pac-rom on it recently, too.
This problem has happened off and on since CM9 perhaps even before. I don't remember if this did happen in WebOS.
While in use the system will randomly stop responding to touch. I need only hit the sleep (power) button once to put it in sleep, then once again to wake it up and the touch works again for a little while. This is very annoying during games as I have to constantly put the pad to sleep and wake it up to restore the functionality.
Honestly, the pad is used mostly by my son for games and youtube and it has survived several drops. Being a 4 year old he gets very frustrated when the touch stops working, too.
I initially thought this was due to my son installing tons of random games and applications but even after fresh wipes and OS installs it will still freeze.
Is there any way to troubleshoot this? Any linux/android log files that contain information related to the "touch" driver? Should I just try to order a new digitizer? reseat the current digitizer?
Thanks for the help!

[Q] Erratic Touchscreen Issues

No matter what I do and however many times I flash cm7, I seem to have erratic touchscreen behavior.
The nook is BRAND NEW (two days) and I flashed it with cm7 7.0.2 stable (after phiremod's 6.0 & 6.1) and flashed it about four times now.
I have tried it with the OC and without.
It's not the SD - it doesn't matter if it's in or not.
Not the wifi, since I didn't even set it up the third and fourth time - it was too erratic to even try.
Plugged in or not... still the same problem. Doesn't seem similar to the other forums topics about touchscreen issues WHILE charging.
Screen is near spotless... no smudges.
It is important to note, that it waits until I have done a few things to start going crazy. I restart it and it's fine, until I do some cpu intensive stuff - live wallpaper is the simplest activity that causes it.
Any ideas?
I have also tried NSR (screen re calibrator) to no avail.
Would love a quick fix rather than re-installing stock and returning it and convincing them to replace it. I am not sure if it does it with stock... didn't wait long enough to find out before flashing it.
have you tried a screen protector? my screen wasnt the best for precise touches but since i put a screen protector on and clean the screen regularly it has since changed my problems to almost non existant.

Others may be able to help you more than I can with exactly when the CM7 may be doing this, but returning to stock to find out is actually not hard at all.
In the development thread there is a post that has the 1.2 stock zips (one keeps CW in place, the other returns it completely to stock). Which ever one you pick it's still just as easy to return to stock as to reflash CM7 again. This is especially true if you used a SD card with CW to flash (which is what I do), since when you want to go back to CM7 you won't have to worry about flashing CW to emmc again.

Hate to say it but it sounds like it might turn out to be a hardware issue. This is not a CM7 issues that I've seen from anybody.
Can you describe the behavior in more detail?

It seems to start selecting things on its own after I have been using it for a while. It's difficult to describe except that there isn't really a pattern... it selects something different and keeps at it. At one point I almost purchased an app from the market before I had to power down.
I will return it to 1.2 stock and report back. I was mainly wanting to know if these was a commonly reported issue or not. I guess it's not. Thanks for the help everyone!

So my NC started to do the same thing last night. I have been running CM7 (at 7.0.2 now, but nightlies before then with dal's OC kernal) for quite a while now with no problems. Only thing I did last night was to delete about 1GB of ebooks off of my NC and reload them through Calibre.
I left it alone last night after it started doing it and then this morning it started doing crazy touches again. I was in Aldiko and it was selecting books and turning pages at random. Rebooted and it seems to be fine for now. Little odd though considering it has been running perfect for a few months.

So now I have installed nook stock 1.2 and NO PROBLEMS. I have run everything trying to get something to happen, and nothing.
Is it possible that I installed something the wrong way with cm7? Could I have used the wrong CWM version (3.0.0.6)?
Should I try cm7 7.0.2 or something else again?
I would try and return it, but I can't recreate the problem... if I could, I would be in their face right now.
Thanks for the help so far.
I think I solved it!
The newest nooks (in the last week or so) have 1.1.0 factory stock. Apparently there is a glitch that has been reported a lot recently about handling the touchscreen AND the SD card. These were fixed in the 1.2 upgrade. SO...
1. I flashed factory stock back on (in this case I went back to 1.0.1)
2. Then turned it off and "restored factory" settings using "Power+N" to turn it on. Repeated that a second time to get B&N's factory reset screen to come up.
3. Pressed N twice to accept restore prompts.
4. Upgraded to 1.2 (no glitches already by this point with touch or SD)
5. Booted CWM 3.0.0.6+
6. Formatted /system & /data
7. Flashed phiremod 6.1
8. OC'd to 1.1Ghz
...and DONE. No problems so far. I still see the "Read Forever" opening screen, but it still works wonders. WAY better than before.
I am still having issues with Wifi, but I can deal with that.
Now to attempt dalingrin's OC to 1.3!
Thanks guys... hope this helps others.
I think they call it "Touchscreen goshting". It started happening to me when I rooted the nook and the keyboard would go crazy. Now in CM7 7.0.2 with latest kernel, it happens more frequently. About 5 minutes in from boot, fast random touches occur. Most of the times this gets fixed by pressing the power button to turn the screen off (sleep), and on again. I guess it could be a hardware issue where some devices are affected. I haven't tried any recalibration apps to try to fix it yet, its kind of annoying when it happens in fast intervals.
I had weird touchscreen issues when using the interactive cpu governor. I later found only performance is supported. Using performance setting, everything works much better.

I had the same issue. I exchanged it the other night and now my new one does not have the problem. It probably a hardware issue...i hope you are still under warranty!

[Q] Tried Everything - Touchpad Screen Unresponsive (CM9)

Hi
Looked for this issue on the forum and can find instances of it happening occasioinally, but not with the frequency that i have. Symptomns are that the screen will stop responding to input. I.e the screen stays painted but does not respond to my pokes or pros. Flicking the screen on and off for a split second fixes it. I believe its related to software or resource usage -sometimes i can go for ages without issues, however in the last half an hour this has happened around ten times. please help!
I have tried isolating it down to a particular app with no success, and also changed the CPU governance settings, asgin unsuccessfully. I have no such issues in WebOS.
Thanks.
ps running CM9 alpha 2, but had same issue on 0.6
flash the latest nightly.
screen unresponsive281]flash the latest nightly.[/QUOTE]
Thanks for the reply. I may consider doing that, guess that with a Android backup I don't have much to lose. Would like to avoid it if possible as not being as widespread they aren't as proven and I've ironed out all other issues in alpha 2 such as wifi etc ...
Thanks
the latest nightly offers quite a few fixes.....
including vibration from sleep and tons of other stuff. not much can go wrong.

There has been loads of improvements in CM9 wifi has been fixed sound distortion when the screen off is fixed many speed fixes we now have themes working
Do a nandroid backup in CWM then copy that to your pc for safety then wipe system partition DO NOT FACTORY RESET OR WIPE DATA or you will lose you data, then flash latest nightly and latest gapps then wipe dalvik cache/cache partition's then in advanced fix permission's and reboot system
Well.... I dip my hat to you guys.
Went ahead and installed the latest nightly - even if it doesn't fix my issue, I was suprised by how polished it felt compared with Alpha 2. Typically with bleeding edge stuff I'd have expected to have more issues, but alls I had to do was reinstall YouTUbe and flash the gapps-fixer zip for my Calender sync, plus I see lots of lovely new settings to play with.
Will report back if the screen hangs again, here's hoping...
Frustratingly this issue has started happening for me again running 31 May nightly - touch screen has become unresponsive half a dozen times in the last ten minutes.
Maybe trying wiping it and doing a brand new flash from the latest nightly. (I know it sucks to reinstall stuff, but maybe there are some leftover codes that is causing trouble.. )
i agree either to wiping data or up your min cpu speed as it might the amount of apps you have installed that auto start/resume when turn on the screen..

Moving to Q&A
I only had that problem once. Rebooted by holding home and power never had it again.
Sent from my YP-GI1 using XDA
Had this issue yesterday for the first time since installing cm9 6(?) months ago.
Tried a nightly build as suggested, but given the rarity in the first place, can't be sure it's fixed
This happens to me all the time across all ROMs I have tested.
This happens in OaT's and turning the screen off/on, fixes it temporarily.
This happens in Butta, but turning the screen off/on does nothing. I have to reboot using power/home.
I have also been unable to find a specific app that causes it, but it does seem to occur more often in graphic intensive games.
I can go for days without it happening, then BAM, it stops responding to touch, from that point forward, no about of reboots or full shutdowns seems to fix it for several hours. I'll reboot and sometimes it'll be immediately, sometimes it will be 3-5 minutes, but it will happen again.
Then a few hours later it'll stop happening and I'm good for a few more days.
Do those of you using CM9 find that screen off/on fixes it, or do you need a full reboot?
I am running the night lies and have to say that the only time I experienced this was with the may nightlies. I have not experienced any issues with the 7/04 nightly.

Interestingly enough I think I found out what causes the screen to stop responding. When the TouchPad is locked in landscape and then I turn it portrait while its still locked, then the screen becomes unresponsive. Does that make sense?

I take it back. The screen became unresponsive even in landscape mode. There goes my well formed and thoroughly investigated theory.

I've been using Nova Launcher ... I switched back to Trebuchet and it appears to be working normally. Of course I may be spouting this half-cocked like I did before. What launcher are you using?
I run SPB 3D launcher and do not experience any response issues with the latest nightlies. I use my touchpad constantly as a laptop replacement so mine gets a workout every day. To my knowledge, no one was ever able to find any one app that was responsable for this behaviour but it was noted in earlier builds.

I too still have this issue - as per others, fine for days, then it will occur consistently and I keep having to screen off/on and eventually it stops of its own accord. Am sure its a software issue, but someone here says they also had it in WebOS and HP provided a replacement.
http://rootzwiki.com/topic/20740-screen-unresponsive-in-cm9/
For me as simply flapping the screen on/off fixes it and I've never had the issue within WebOS, it has to be software - this started as soon as I first installled CM9.
Bump - still no fix identified for this by anyone with this issue please?
To anyone still following on, followed nevertells advise and completely started again from scratch and it happened after about twenty mins of using the stock browser. I think i've tried not using that app before so am just going to assume that this is either a software bug or a hardware issue that only manifests itaelf within Android

[Q] Touchscreen sensitivity issues in CM9/CM10 (but not webOS)... any advice?

Hello, I am having some touchscreen problems with CM9 and 10, but not with webOS. Namely, I think that the tablet is detecting double or even triple taps when none are present.
In CM9, when I execute a longpress (to move an app for example), the tablet just kind of... spazzes out, and in general nothing happens. In CM10 it also does this, and almost everytime, it starts whatever app I was pressing on.
Also, when I try to type in the CM10 keyboard, 2-4 characters are being entered at a time, unless I touch incredibly lightly, and even then, I will often get two.
There are other symptoms along these lines, like trying to pull up the notifications, etc. This does not appear to be isolated to any one portion of the screen, it is happening everywhere I could check it.
This CM9 versions I have tried are the nightly 0715, and whatever the latest nightly was about a week ago. The CM10 version I am using is jcsullins' 12/16.
As stated, I have zero issues in webOS.
Is there any way to change the touch sensitivity? Am I a moron and doing something wrong?
Thank you for your help/advice.
To clarify, I think this might be two separate issues...
I'm not as concerned with the CM9 issue, as it is only a mild annoyance and everything else is outstanding. CM10 is virtually unusable, however, so I'm hoping someone can help me out there.

I've not had this issue, but this might help. Go here : http://goo.im/devs/jcsullins/cmtouchpad/testing
Download the touch pressure utility (should be the last one) and flash it. Hope it helps.
Good luck.
As an update, after shelving the touchpad for a few months, I have revisited it, and, after doing a clean install of jcsullins' CM10.1 w/BT Fix (20130808), the same issues as above still persist. I've done the following, although I didn't really expect most of them to work:
Switching to stylus mode (no difference)
Changing the accessibility settings for touch & hold delay
Even went so far as to install another launcher (nova) to ensure it wasn't trebuchet (not that I think it was)
Same for the keyboard
This has never been an issue I've seen in webOS... additionally, I don't remember ever having any issues in CM7 either. I did play with webOS for some time today to make sure it wasn't some kind of hardware failure between now and the last time I used it frequently, but I failed to reproduce the problem there.
Is there any light someone can shed on the subject? Thanks!
Thanks for that Chicle_11... I don't know why I failed to mention it, but I did also try the patches with CM9, but it is to my understanding that they were rolled into cm9 nightlies at some point?
I wonder if I could be having a minor hardware issue that just isn't severe enough to display in webOS, because I can't seem to find anything else about this, especially the keyboard problem with CM10. Its bizaar for sure.
Started experiencing the same issues after upgrading from cm9
I recently upgraded from cm9 to cm10.2 and immediately noticed this issue. There were no such issues with cm9. When swyping on the keyboard (any - Google, Swype, etc.), the system registers that I lifted my finger, and so garbage gets typed - you can also see the effect in the trace. When typing instead, letters sometimes double-up for a single press. When playing games like PvZ2, dragging a plant results in a release of the plant before I've lifted my finger, and sometimes the plant gets planted across the screen from where my finger is pressing.

Touch screen temporarily unresponsive

I had a similar problem(but worse) sometimes when using the stock rom.
I've replaced the stock rom and been using CM10.1 on emmc.
Sometimes when playing games the touch screen may become unresponsive but the 3 standard buttons still would work.
(as well as the hardware buttons.)
When this happens I'm not able to click on any of the icons on the home screen. (none of the control buttons work in game, either.)
I wonder if this is a hardware problem, CM10 problem, or a problem with the coding of the game (dungeon hunter 4.)
The problem actually does not last. Nook HD+ recovers by itself after about 1 minute.
Else, I could also click on the power button to turn off display and turn it back on.
Once it's back on everything is working including the in-game controls.
Does anyone have a similar problem?
I doubt this could be a bug in the game (Dungeon Hunter 4). The game is very buggy but when I play it on Nexus 7, I never experienced any control button issues. (Though it does crash "a lot" and sometimes more often than on the Nook HD+)
I had this experience before, just because of the memory going low so it needs time to respond. I advice you exit completely all your current apps and clean ram memory (also cache memory using Clean Master (Cleaner)) before playing games or heavy task. Also remember sometimes turn of completely device for few minutes and turn it back on to use. Hope this help

Thanks. I appreciate your help. I had this problem again today and I noticed the available ram was indeed quite low at the time.
Although it seemed unresponsive, it seemed more like being extremely slow.
Somehow if I turn off the display and turn it backs on it gets a bit better.
I suspect dungeon hunter 4 has a memory leaking problem. (memory not released completely if reload an area many times.)
I tend to have this problem if I load a lot of data in the game several times.
Strangely this does not occur on Nexus 7 based on the latest patch.
I searched in xda and it seemed last year Nexus 7 also had the same problem especially when playing certain games.
So I think this issue may come from rom which is used by nook hd+, with this issue i strongly recommend you post directly to verygreen original topic for him to discover. But if you can attacht catlog file also is better.
Here is his topic: http://forum.xda-developers.com/showthread.php?t=2263553

Thanks. I deleted the game as it is very buggy, crashes often and with many in game bugs. I'm finally done with it.
If I encounter the same issue with other apps I'll definitely upload the log.
I had it on all roms
Hi,
No, you are not alone. The issue occurred on all roms I used so far.
Indeed it mostly shows up in games, though I think I noticed it in other apps too occasionally.
I usually use the power button, but I'll try clearing the memory in the future...

[solved] [SM-T813] Random Reboots. Works for days then for not even a minute

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.
