Anyone know why the digitizer would have a very slow response after a hard reset? My TH froze last week, and the only way I could get it back was to remove the battery and re-synchronize. The first thing I noticed was the digitizer is now very sluggish to taps and grafitti. It even hesitates when I press the sync button.
May be there is very small dust particle trapped between the screen protector and digitizer surface.
That's not it - everything was working fine before the crash, and I didn't change the screen protector in between. Besides, that still wouldn't explain why there's now a very noticeable delay even when I press the sync button.
Figured it out. I have a keyboard driver (Belkin G700) for a Belkin keyboard I had gotten a while ago. When everything reinstalled after the sync, the driver defaulted to 'on'. I disabled it, and the digitizer is back to normal.
