Irritating Touch Screen Issues - Galaxy S6 Q&A, Help & Troubleshooting

For the last several weeks, I've been having problems with my touch screen.
It will have lots of times when it doesn't register touch, like when I'm typing, scrolling, or when trying to pull down the quick settings/notification bar, it takes several tries. Also, when I set the phone flat it won't hardly register any touch at all.
I have tried the following to try and resolve it:
- complete factory reset
- changed launchers and keyboards
- making sure screen is clean/fingers aren't cold etc
- changing the long press settings for the phone
Anyone else experiencing these problems? I'm so frustrated, and I'm planning on calling Verizon to see about getting a replacement. Any suggestions would be greatly appreciated.

Had the exact same issue as you and got a replacement and every single issue went away.

Unfortunately I had a defective unit just like yours it was way more apparent when the phone was laid flat on the table and you attempt to make touches
Fortunately I was lucky enough to be within my 14 day return window.. If you're not then it looks like a warranty repair unfortunately.

Hardware Keyboard quits sometimes. Help Touch Pro device

Need to know if anyone here with a Touch Pro device ever had the hardware keyboard just stop working. I cannot time when it will happen it varies. I can slide out the keyboard to respond to a message the backlight is on the all of a sudden after a little tyoing the light goes off and no key I press shows up. All of the screen keyboards work no issues. I have to do a soft reset to get it back. Today before it locked one of the keys I pressed was still in memory and I had rrrrrrrrrrrrrrrrrr all over the screen. I had to take the pen and cancel the message but the keyboard was not working anymore.
I called Verizon they had me change my backlight setting thinking it was that but of course it did not. Now they are saying a device replacement...guess I should have gotten the insurance.
Is there any advice someone can offer me on this problem?
I've had this happen to me one or two times, and the times that I've had the problem I've fixed it but soft resetting. I've just brushed it off as one of the quirks, and I haven't worried about it since it hasn't happened in a while. If it continues to occur I guess I would see what you're carrier can do for you
Mine did that a mutliple of times. Same exact scenario. Since I upgraded to energyrom, hasnt done it once. If I had to take a guess, some glitch in the preloaded rom?

Screen akignment issue

Hello!
A few days ago I started experiencing an annoying problem with my HTC Touch Pro which I have for almost a year.
Every once in a while, the touch screen goes out of alignment, and doesn't respond correctly to my taps.
I use the screen alignment app that in the start > settings > system tab, and then two things happen:
a. it usually takes at least 4 times until it aligns correctly, and sometimes I give up and have to soft-reset my device.
b. the screen goes out of alignment again, after some minutes or hours!
This is very frustrating...
Does anyone have a solution?
My eternal gratitude is promised!!

Hi,
This looks like your touch.dll being damaged. Guess the only solution will be a hard reset (and lose all your settings and dat) If after that, your screen is still out of alignement, you're in for a hardware repair (warranty ?)
Dirk
Sometimes touch screens can 'stick' down, which can cause problems for the device driver, wild alignments being just one of them. I had an Xda II which was a pain for doing this. A short sharp whack, face down would cure it, but it steadily got worse, and the repeated percussive maintenance was eventually the death of the thing.
If it is still in warranty, and you can demonstrate it to to the supplier, then a warranty repair or replacement may be the best remedy.

[Q]Keys not working..help needed asap :(

Hello,I bought a HTC Desire S around 4 months ago.
From past 2 days i have lot of problems with it.
1.Home screen button not working
2.Q,A keys are not working while typing(they work when i rotate the screen)
3.Wen i rotate the screen and start typing the whole keys on the least bottom dont work.
4.Sometimes if i press back key it goes to selection option...sometimes whole phone hangs.
5.Im not able to download from market...after i click download it shows downlading icon but it never starts download.
I made factory reset for couple of times but no use.
Any one have some suggestions?
numbers 1 to 4 seem like some sort of problem with your touchscreen... Have you tried wiping it with some clean cloth after breathing on it? My back button has some issues registering touches once in a while, but wiping it helps always
Regarding 5, I don't know really, but have you tried using the webmarket?

ya i tried wiping it but not working
Does the area where your Q and A keys are when in portrait work when the keyboard is not on? Can you use it to click items, scroll webpages etc?
One other thing you could try is the calibrate option for the keyboard. (somewhere in settings-> languages I think, it's been a while since I ran an Sense ROM).
If both yield no result, it sounds like a hardware issue to me, and you might be best of to invoke your warranty.

[Q] Ghost touches (especially in dock) with TF700t. How to fix this?

I had issues with my Asus TF700t that quite often it did not react on touch gestures.
And on the home screen the "change backround" dialog opened sometimes without any touch on the device.
This happend very very often when it was in the dock, but also without the dock (less occurence).
Now i know that the reason are ghost touches. By the usage of touch test apps (e.g. "Simple Touchscreen Tester" oder "Yet Another MultiTouch Test") i realized the ghost touches.
This touches are recognized always on the same coordinates. The multitouch test app detects 4 fingers on the same y-axis.
When the tab is in the dock and i open it completely to the maximum the two bolts from the dock are pressing very strong to the background of the screen glass. This is causing the ghost touches.
I opened the tab and tried to find what could be wrong (especially on the area where the touches are detected).
Anyhow i could not find anything. The only thing i noticed was the on the y-axis of the ghost touches the screen is fixed on the left and the right.
I check everything else closed the case ... but the ghost touches are still present.
Any idea how to fix the issue??? Who else realized the same issue???
Attached some screen shots from the touch test apps.

Sounds like you have a digitiser hardware issue to me. Had the same on my Surface RT. Only fix was to get it replaced.
Yeah, I just got mine back from warranty digitizer recalibration.
tapatalkin'
Another TF700T here that just returned from RMA with digitizer repair. Went very smoothly for me and I have a TF700T that again works extremely well.
Do they replace parts or just recalibration? Is it possible to so this myself?
I have unlocked bootloader and i do not know if they will repair it without any problem. Any experience on this?
Hi,
First, sorry for my english...
Second, I have same problem since saturday 24 august with my TF700T. Buy november 2012.
I tried to updated to android 4.2 But it didn't solve my pb.
I try "Multi Touch test" app and I observed same problem than mr_cg. Thanks for your good description "Ghost touch"
Ghost disappear when i unplug and re-plug dock, (some time two or three time) but just for some second ...

If you are root, you can perhaps try this app:
ILITEK Touch Utility
or
(less chance i think, it did for S2,S3) TouchScreenTune
Me i am not root, but if it is working for you, perhaps i will try to be.
Thanks for your help

Thanks for the hint. I tried the apps, but both do not solve my issues.
ILITEK ... descriptions sounds good, but unfortunately not working (i get always "access denied" even i have root for sure).
TouchScreenTune ... Based on description it should be also good tool to reduce/improve situation with ghost touches. Anyhow ... it is not working with TF700t.
I am just thinking if i should open the case again???
If with root permissions you don't find solution ... I think i should call Asus support for my first RMA..
snif snif.
Thanks for your return. I win a lot of time.
Same issue
I'm having the same issue here, but only when docked. Seems like I'll stop using the dock since I am out of waranty because I unlocked the bootloader ...:S
I've been having a similar issue very badly on the right side of my screen, it was practically unusable. I am also out of warranty because I'm unlocked. What I did to make it at least somewhat usable was go into the build prop and change my max touch screen events from 200 to 4, and changed my touch sensitivity from .001 to 1 (this setting may have only been available on CROMI. Anyway, now my touchscreen doesn't work on the right side, however it does work everywhere else, and most importantly I can still use the tab as a laptop in its dock. It's a bumm it doesn't work right, but it's better than a total loss!
Sorry guys, it is a failed design problem due to connection to the touch screen. see my post in the "so i took it apart" thread.
Cost me a ruined lcd screen to figure it out

What a great thread! Thanks, I've posted this elsewhere but having just send my TF700 back to ASUS I now have a pretty good idea of what might have been wrong with it. Here's what I posted and what I've told them anyway. I've overlooked the Ghost touches unfortunately, so I will let them know that (if they don't already)......any comments welcome...
Asus Transformer S/N D20KAS016975
I've struggled with this tablet since purchase in April this year, not being at all familiar with tablets I did not know whether it was just me, the general setup, or the tablet itself at fault. Most certainly the performance is not satisfactory. I have done three 'Factory Resets' and numerous Soft Resets.
Intermittently, the tablet will scroll and flash through various apps, when I open it. Originally File Manager would open itself up, then I got the feeling the Weather app would upset things. Sometimes a browser would make it do the same. Then I tried various Launchers, but the best of them (I think) sometimes shows the menu unannounced. Same thing, on and off until I intervene.
It is also prone to do this just sitting open by itself.
Clearing the caches sometimes fixes this. Sometimes this will stop by itself, other times I need to either close the lid, press the lock button, or turn it off. Then it will be OK.
At times Gmail will scroll randomly through the accounts, messages, labels etc.
Every browser I've tried will sometimes shut itself off, especially if I try to type something into a message box, usually when I've spent some time doing this!
Occasionally I can feel a slight tingling sensation when I'm lightly touching the back of the screen.
One other thing: When left overnight the mouse doesn't work and the tablet needs to be turned off and on again for the mouse to work. I also think the screen doesn't turn off sometimes (can see a light).
At other times the whole thing works just fine.
Hope this helps.
Regards
Grant
Tablet arrived back this morning

Tablet arrived back this morning and seems all OK. Report indicates they replaced the LCD panel (new) & replaced the touch controller board (also new). And did various tests. Good service I think, no fuss. I'll let you know how it's going in a few days.

Grant,
Was your tablet still under warranty? Did they charge anything? I wonder if they redesigned the digitizer connection or just put a new screen which will wear out as well. The digitizer connector runs along the bottom left of tablet screen. Same area is being pressed when you close dock, which wears it out.
You can go to developer settings and enable "show touches" (lowers tablet performance) then press on the bottom left edge of the screen, roughly 1/3 point of its length, and see if you get the ghosts to appear.

Yes, still under warranty (problem was there from day 1 although I didn't realise it at the time) and no charge. See attached pdf Customer report. Shows replacement Led panel, & controller board. No sign of ghost touches so far, and really working well actually. Early days yet, but I also note elsewhere in these forums someone mentioned their tablet not working properly 'upside down'. I neglected to mention it earlier but upside down isn't as funny as his respondents made out. I use mine often lying on the couch watching TV, with the tab upside down. Reason I mention it now is that mine acted up in those circumstances too. Anyway, that's fixed too.

Touchscreen randomly not working

Hello guys,
This is not necessarily a specific S8 plus thread, it's more of a software/hardware general related issue. I just replaced my display two weeks ago because I cracked the screen and the display a while ago.
After replacement, I got the phone, everything was good until I dialed *#0*# and started testing the touch. It appears that theres a portion in the middle of the display that is not working (the boxes wont go green when touching them). The thing is that, sometimes, the touch passes this test as in everything is ok and sometimes, it fails.
From time to time(pretty frequent) it randomly freezes and I have to hit the power button to open and close the screen to make it work again.
I just flashed the android Pie hoping a complete erase would fix the thing but it appears it didn't. Do you guys know any solution to my issue besides returning the phone in the service?
Thanks!
