    The following problem started this morning all of a sudden. I can't remember anything that might have triggered it:

    I turn on my Pre (original) and start launching apps, navigating around, the usual stuff. All works as usual, but when i don't touch the screen for about 2 seconds it stops responding completely. I have to use the power switch to toggle the screen (off and on) and all starts again.

    If i keep touching the screen directly after switching it on, it keeps responding. That way i can use the touchscreen as long as i want. But as soon as i stop touching it for a few seconds it stops responding. That is repeatable.

    It is independent from anything else i tried: plugging in the USB charger, using the touchstone, wriggling the slider etc etc. - always the same problem.

    So i tapped, switched the screen, tapped, switched, tapped, ... oh, and even that doesn't work when the pre is on the touchstone. I have to turn the screen off completely before turning it on again or the touchscreen won't respond.

    I even doctored me Pre but the problem is still there.

    There's nothing special in the logfiles (before and after doctoring).

    Anyone else with the same problem? And possibly a solution for it?

    Thanks...

    Have you been seeing any "ghost" taps on the screen while it's on? Also, are you overclocking? If so, which kernel and as what frequency?
    I don't understand the purpose of the line, I don't need to drink to have fun. Great, no one does. But why start a fire with flint and sticks when they've invented the lighter?

    Let's all give thanks to the app that started it all.

    I know about the "ghost tap" effect. I experienced it myself, when i used a cheap chinese charger instead of the original one. I later confirmed that the chinese charger had 5.3V

    In short: No ghost taps.

    Overclocking: well, wh doesn't? I use the 800 MHz fix setting for about a half a year now. Never had any problems. I used to monitor temperature very closely for the first month or so. The pre never came close to critical.

    Oh, and i use a Mugen 1350 mAh battery for several months now.

    It worked well for months with Mugen and overclocking. I can't imagine that one of these is the culprit.

    Anyway, i talked to customer support this afternoon and i'll get it repaired on warranty.
