My Sprint Palm Pre has begun having problems detecting touch and responding correctly. For no apparent reason, when I touch the screen these days the system either doesnt respond at all (ie nothing happens) or it responds as if I'm pressing somewhere else on the screen. For example, dragging up to unlock the screen from sleep mode can send the lock icon spinning around the screen, up and down, left and right, even though I've lifted my finger from the screen. Other times, when I tap on the screen, the "ripple" icon that shows where you touched appears elsewhere on the screen. I'm frequently tapping things open or closed that I haven't actually touched.
It's super annoying and sometimes makes the phone unusable. Funny thing is, a restart or battery pull will usually fix the problem for a while.
I don't have Preware or any patches/themes running (I doctored my phone several months ago) and haven't updated the OS recently.
