Hey, I ve been using Verizon Droid Pro on GSM networks almost a year now. I was all happy with it since there was no major problems.But since 2 weeks it really start to act strange on calls. During a phone call voice suddenly disappears. Even if I restart the phone it doesnt seem to help. I even went back to 2.2 but the problem is still there. It doesnt seem to be hardware problem, cause sometimes the voice is there for a while, but suddenly disappears during a call. Please help me. Maybe there is some kind of tweak in system files?
