touchscreen problem - dead row
my Atrix is behaving strange lately, but i just don't want to let go my old lady... so anyone has any idea re. root-cause of the problem?
i got aware that the touchscreen had stopped working for a particular row, next to the volume control buttons. for me, it's been clear: hardware failure.
i wanted to see the symptoms in detail, hence installed a diagnostic app to check the touchscreen and identify the "dead zone" properly.
when playing around, in the endeavor to paint all my screen blue, swiftly swiping my finger across the touchscreen. after a while, the phone's reactions became sluggish, and the home/back buttons would not bring me back to my home screen. so i switched the dialogs off and on again (power button). and the home/back buttons returned to work fine.
to my utmost surprise, the touchscreen problem had gone!! no more dead areas in the touchscreen!
only after a while, the problem returns and the very same row is dead again regarding touch inputs.
Amazing! and this is fully reproducible! it's necessary for the app to react sluggishly (which is only randomly achieved), and the home/back buttons to stop working, to temporarily 'heal' the touchscreen.
So it's not a hardware, but software problem?
what's your opinion?
BTW, I am running a rooted stock release, european version, atrix 4g.
