Hi all! Just bought the phone and encountered a problem. For incoming calls I can not hear anything and caller cant hear me. After about 8 seconds to wait for the call begins. If the answer to a wired headset, the call is not starts at all, and i cant hang up. Saves only the restart. I tried different versions of firmware (Official or not). No change. There are solutions to the software or do I buy a broken phone? I apologize for my English, but my family forums, I have not found an answer to this question.
