as stated previously, had screen and backbutton problem and tried everything. Finally thought maybe a screen intensive app had gone haywire and deleted everything non-essential. Saw drastic improvement but would still spazz on occasion. Locking/unlocking phone would generally fix this for a while. Since phone was rooted and I had the money to replace it if needed, decided to try a fresh rom. Wiped everything, installed Smoked Glass version 11, and haven't had a spazz yet a week later. The back button still needs to be pressed repeatedly to register sometimes, as well as about 2 mm of the left (bottom in landscape) side of the screen, but I believe this to be the result of a drop. Otherwise, fresh rom seemed to do the trick, plus I didn't have to get the phone re-flashed to metropcs. Just had to rewrite the apn settings.
On a side note, I was told by the metro guy who flashed the phone that metros browser would block app downloads, so I would have to be on wifi to download them, but I could use them with metros 1x internet. I've heard others on various forums confirm this. However, I have always been able to download apps with 1x with no problem. Can anyone confirm or deny? Wondering if the rom has anything to do with it, I upgraded from v.6 and had no prob with it either. Appreciate any feedback.
