[Q] HP touchpad cyanogenmod touchscreen issues.

I have been having problems lately with my HP touchpad on CM9. They are as follow: the touchscreen goes crazy and does all sorts of random typing and button pressing. At one point I could not use it so I webOS doctored it up and then flashed CM10. So far it fixed the issue but now my corner "back" button only works when you press it on the side closest to the middle. Some other buttons are like this or do not work completely in apps. I don't think it could be a hardware issue as I have always been careful with all of my devices. Thanks in advance!

Can you completely rule out hardware issues by testing your screen using a drawing app?

I will try that now.
Update: Ok please try to work with this: In landscape look at the arrow, the width of the arrow, that entire section is not working from bottom to top. You have to almost tap on the very right edge of the back arrow. I still do not think it is hardware.

Bump, please help

I'm on CM w/android 4.2.2 and have similar screen issues... screen sometimes goes a static non-moving "fuzzy" blue... not sire if ther is any pattern to it or not, but reboot fixes it for a while.
lately I've noticed that ill get artafacts... fpr example todays google doodle viewed using stock android browser app will often produce black a d white horizontal artafacts. perhaps driver issues?

You don't say what Rom you are using but it certainly works on Jcsullins latest.

Evervolv but now i am thinking its an lcd digitzer screen problem cause nothing in that area works regardless of the rom. I never dropped the device so i am not sure why just a section of the lcd screen would stop responding..

Problem with touch buttons

Hello guys recently having problems with touch buttons on my O4X
1. They work if i press the blank space between the icon and the screen (They don't if i press the icons like they moved towards the screen)
2. If i put my phone on a table or any surface other than my hand they doesn't work at all. (or 1 out of 10 presses maybe)
edit: Buttons are dead and the middle section of the touch screen aswell (about 1cm horizontal line in the middle)

Any help ?

Touchscreen Issue

My nook hd smoke grey version is having touch screen issue. I was using cm12.1 5-30 build by amaces. The part near to right bezel doesn't respond to touch. That prevents me from pressing 3 dot menu and letter "p" in keyboard. Rest of the portion is fine.
I thought it was the problem with the rom and kernel and immediately flashed the stock nook hd firmware. The problem is still not fixed.
Is there any solution to calibrate the touchscreen ? I'd be thankful for any useful help.

anybody having sensitivity problems on keyboard after recent OTA? like the A button

My A button not responsive at all, and also the top left of my screen , like when i try to hit back inside facebook for example , not working at all .

I'm having the 2nd part of what you describe. Same area menu button on Google Play store is. Seems to start/stop happening as it wants, when it wants.

I have an S6 (not edge) and am having a similar issue where the bottom rows of the keyboard do not register everytime and also pulling down the notification shade takes a few tries sometimes. Don't know if it is something to do with the cold weather or a software/hardware issue. I am thinking of sending the phone back to Samsung for warranty repair.

Mine is working without a problem. Is the keyboard problem persisting across other apps?

Touchscreen Issue - Touch Detected but not Registered

I find this very annoying, I turned on the Show Touches on Dev Mode, and when playing intense game (PUBG, Mobile Legends etc) there are detected touches but not registered.
What I mean is, when I tap on a button (take for example the fire button to fire your weapon) and lift my fingers up I can see the white dots (Show Touches on Dev Mode) but it doesn't click the button (not Registering the touch).
Anyone else ever seen this? I find this very very annoying.
For the sake of clarity: I use no screen protectors which mean it is pure hand to glass contact. I use all default settings (factory reset). All software are supplied by Samsung and I haven't done anything to them. All hardware parts are stock.
And somehow I noticed this: It won't register only if my other finger are controlling the D-pad which is on the left bottom side of the screen, meanwhile the fire button is on the far right screen.
