Ok- Here's one for you. I too had severe digitizer problems- had to recalibrate every 20-30 minutes in use. Bought my TT last year and the problem appeared a couple of months ago and has gotten worse. It seemed to get worse when I opened and closed the slider. I installed the patch- no effect or it made it worse. Then thought it was a software issue. I did a hard reset, did not install the patch or any 3rd party software except ZLauncher. The problem reappeared. So I did what any real man would do- I took the TT totally apart! I discovered that some of the internal contacts were slightly tarnished (oxidized?) I cleaned them with an ink eraser. I also unplugged the internal battery from the TT while I was working on the TT. Lastly, I discovered a small (approx 3x4 mm) black pad that was stuck on the back and inside of the slider. It's use to me was unknown, so I did what any real man would do- I left it out! I reassembled my TT. The problem is totally gone!! My slider seems to open and close a lot easier. I don't know if the black pad is used for friction or what. I installed most of my previous apps and still no problem! I gave my TT a workout- open and closed the slider, opened and closed various apps- still no problem. This brings me to several questions as to what the problem was. A) The internal contacts were oxidized and this caused the digitizer problem. This would seem to make sense, since the problem developed over time. B) By unplugging the internal battery, the TT lost all power and some unknown program/virus was lost. Ok, I'm reaching for that one! C)The mysterious black pad was the culprit. This could make sense, since opening and closing the slider seemed to make the digitizer worse. I have not installed the latest TT update. I want the sound patch but not sure if I want the digitizer patch. I would appreciate any feedback on this one.
