the screen problem has got me too. I couldn't point the true reason for it to happen, but i'll try the solutions here. Just to contextualize e see if anyone is having the same issue, here's what have happened and how the phone is behaving: the day befores yesterday it fell from my pocket while i was trying to take it out. It showed no problem at all, worked perfectly. then i went to sleep and in the morning screen didn't respond. I reflashed it and now i'm stucked in the time and place settings screen, but now instead of not working, the screen is erratic. touches work as swipes and sometimes it doesn't work at all. but i think the screen recognizes the presses, since when i touch the physical keyboard lights up.
weird stuff.
