I am writing to report a number of issues at the reception, somewhat similar to the iPhone 4-door antenna. The phone usually appears 0-1 bar, from -87 dBm to -107 dBm. Sometimes it also shows "No service" advice on the home screen. Anyway, when all seems well, call, I can hear perfectly well that I am calling for, despite the best on the other side is a bit of noise. The funny thing is that when the call signal strength can be increased up to 3.4 bars. Is there anything from the Administrator of the battery reduces the power of radio when not making or receiving a call?
