Tablet's touch screen issue - Android Q&A, Help & Troubleshooting

Hello,
I have a tablet with Android 4.4.2 (kinda old) and recently I changed its touch screen because it was broken. It's the second time I change this tablet's touch screen and the first time it was working correctly, but now it acts weird. More specifically, it "clicks" at wrong location instead of the location I touch (I have enabled touchs tracking from the advanced menu). It does not click on it's own randomly, it just clicks wrong. My thoughs are that the touch screen was faulty but a second opinion would be appreciated. I'm also thinking of calibrating the touch screen with those apps running around in play store. I can upload a screenshot as well if needed.
Thanks in advance, Michalis.

[Q] Strange screen problem

Hey, I was just playing with my phone this morning and noticed a strange problem... The top part of my screen, just under the notification bar, does not respond when touched, if an app is running. For example, I cannot hit the location/search/layers button in gmaps, or the search button in market (this is only in portrait mode btw), but on the main screen, it responds just fine. This problem did not exist yesterday either, and I have already tried rebooting, and that did not fix it...
Might want to provide a bit more info if you want help.
I.e. What rom are you using, what kernel, any speedtweaks, etc.
Oops, sorry, it just seemed to fix itself randomly, but I am running CM7 1.2/MR2 radio, no other tweaks, just in case anyone else has the same issue in the future...

Click to expand...
Click to collapse
Im hoping it was just a fluke for you, but keep an eye on the issue, if it happens more it would sound like you could have a bad digitizer (its what controls the touch screen)
So it happened again today, not sure what set it off, but this time it wasn't just the top part of the screen. Phantom presses would happen, the notification bar would go halfway down and then pop right back up, the 4 buttons on the bottom wouldn't respond... I did a battery pull, and it seems to have fixed it for now, should I be contacting verizon to replace this one? It is a replacement of my original one (which bricked)...

[Q] Sreen freeze? hardware or software problem?

Hi there to everyone, I broke only the glass on my screen couple of weeks ago (it felt face down from about half a meter, thats stupid) and I change only the glass my self but since then i have a problem with the screen like: if I press a bit harder anywhere on the screen for about 2 sec the screen became irresponsible and also the back and menu buttons, home and power button work normal. If I press the home button it react as it should, it goes to home screen, so it's just the screen frozen on touch and I have to lock and unlock the phone to go to normal. On daily use it's not such a big problem as i don't press the screen too hard, the problem mostly occurs when playing games.
I would try a hard reset but I not rooted as I use some apps that don't work if I'm rooted and I can't save all my settings, saves and apps and personally I hate to reinstall everything back again.
I'm thinking this is a hardware problem but why it goes to normal only after lock/unlock procedure and i also find on a forum that this can be from the screen protector. It's something similar with the phone in this video the difference being that mine it freezing and that it moving by itself. youtube.com/watch?v=isBDKgxB5vs
Did anyone also experience this?
PS. I sorry for my english as it's not my own language but I'm trying to make my self clear as best as i can, Thank you

[QUESTION] Screen Un-responsive

Hi,
My phone is currently acting really weird. For some reason if i touch the screen in the top 1/5 of my screen it shows that I am touching the screen in more than one place (I've switch the "show touches" on).
Was wondering if any one else is or has had the same problem.
Also, any advice would be very helpful.
Cheers!

[Q] N9006 Note 3 problem touch-solve for time, return problem

Dear friends, see this, see in the youtube:
watch?v=ixWozCI8sek
I activated the phone in their own settings of android to show screen touches and strokes that you can see in the video above, and installed YAMTT app to better show the problem.
The Problem on mobile touch in the middle of the screen there is a track that is not recognized touch, but if I press the screen sinking, she returns to work temporarily, and now recognizes the touch - but after a few minutes the problem back and touch is not recognized again.
The screen is perhaps dished up, and when I press down her back to be in contact with the part of the cell that recognizes the touch, but with time the screen should be getting back dished up (this is my guess, not i'm sure).
Detail, not always when I press is running, sometimes I press the screen to the center of the touch again be recognized, but it seems that the phone is registering touches alone.
What would be a solution, and change the screen (it does not mean that changing the screen the problem solved), want to try other alternatives before changing the screen.
Perhaps heating up the screen with hot air, in theory it will expand and become more pliable, and then if I press down the center panel of the phone with something for a while until it cools, in theory the screen would remain indefinitely, and if that is the problem could solve -
Anyone have any thoughts, has been there?
Thanks in advanced!

After Rooting : Touch Screen Behaving Weird

Hi,
I recently rooted my Note 4 (in efforts to installing a custom Rom on the device) and everything went successfully until I realized that my touch screen positioning is all messed up.
The touch screen is responsive but where I click and what gets selected is all effed up. For example- the option which is at the bottom right on the screen gets selected when I press somewhere in the middle right section of the screen. It seems the touch option is all scaled up.
I installed Samsung default Rom in efforts to fix this but the problem still persists.
Any idea on what can fix this?
Cheeers,
K
bump !
