I can confirm that the phone freezes during some calls. I was talking to my friend when I heard the call waiting beep. I went to go to my phone and I could not turn it on, it stayed black. I was still able to talk to my friend from the first call, but had no choice but to take out the battery to get back into the phone. I am using stock rom but installed the 25012 manilla 2.5 upgrade. The thing is it's not every call, but it does happen at least once a day
