And I haven't a clue! I'm on Sprint, non rooted, and I have to say my woes began with the software update to 1.80.651.10. First it was bluetooth pairing/dropping issues. Now, the screen froze one day, the phone was unresponsive (including the power button) for a good 20 minutes. When I plugged in the charger, even the light wouldn't turn on, so I feared the worst. It "came to" on it's own accord. Just this morning, it did the same except it froze and became unresponsive while charging, so the screen was black. This time, the charging light stayed on but again, no response until it came to again, about 20 minutes later. Any ideas for the cause? I really love(d) this phone but now I wonder if this is going to last me a two year contract. Thank you.:-
