First of all, thanks for reading. I love this message board. I've been using the S2, unlocked on Tmo for 6 months now. These are my annoyances: 1. The screen brightness changes to very bright sometimes, when coming out of the unlock state. 2. When walking, with the phone in my pocket, if I receive a text the phone will on its own unlock and begin opening other apps. 3. USB mode is very inconsistent. Sometimes it will work, sometimes it won't. After about 6 connects and disconnects I can then move files around from the phone to my MacBook. 4. Sometimes, when texting, characters that I am typing do not appear. To get the messaging app to work correctly I need to shut down the app and reopen it. 5. The phone was useless at Coachella. My friends with Tmo and old blackberries had service. I was saddened that I didn't, boohoo. Thought I'd throw that in. Hey, thanks for reading! Solutions to the first 4 issues? Thanks.
