[Q] Touchscreen input problem

Hi all!
I hope someone could help me,
My Desire Z touchscreen works weird, sometimes it does 2 unusual things:
-sometimes when trying to scroll it will zoom in or out like there is another finger there but there is not. If i run pointer location test, then it shows there is screenpress in the middle, but im not pressing it. the only way to fix it is to turn off the screen then turn back on.
-other times, the problem is similar, about 1/4 of the touchscreen in the middle/horizontal does not recive input. And the whole screen wont recognize touch correctly.
The problem happens mostly -but random- when i play games, or read pdf!
Is this problem related to the digitizer? I have tried more ROMs, the same problem. Not charging, no screen protector on the device, no break on glass.
Thanks in advance

[Q] Possible to undim without activating screen?

When the screen auto-dims before timing out and I touch the screen to undim the display, the touch registers which gets annoying, e.g., when that means that menus are popping up in the open app and I have to touch again to close them. Is there a way to emulate iOS behavior here, i.e., when dim the first touch to the screen undims and only successive touches register?
Man, does anyone have a solution for this?

[Q] Touch Screen issue (P601)

Hello. I am experiencing a problem on touch screen. It's not that "shaking screen". You can see at youtube (watch?v=4GWAYOPo8Ww).
This problem on the video happen sometimes. It happens when I turn on the screen. If I change the screen orientation or turn off and turn on the screen again, it goes back to normal.
Could this be software issue? Or hardware?
It never happens with the S-Pen.

Touch screen help

Hi all.
My wife's s4 mini started to play up, 1/4 of the touch screen from the bottom has stopped working. this means she cannot assess app tray, call log etc.
the screen itself looks fine and all other parts are responsive to touch.
I manage to reset the phone by turning it sideways to assess all the keys but this has not solved the issues.
Do I need a new screen or can this be repaired?
thanks
