Touchscreen not detecting multitouch well?
So I noticed this issue a few days ago... my screen doesn't appear to be detecting multitouch worth a darn anymore. It used to work perfectly, and now I can't even play a game. Single touch works fine, but as soon as I put two fingers on the screen, sometimes it just doesn't detect either, and sometimes it detects one. It also happens when I have two on the screen and remove one; it will stop detecting the other.
Does anyone know what might have caused this? I haven't done anything differently in the last few days aside from going back to apex and re-enabling widget locker, but I don't think that should make a difference...?
