hello. Each time when i listen radio more than one hour, the display the phone is blocked: black screen, radio still working, no action when i push the buttons.

If i remote the headsets and then put then in again after 5, 10, 15 seconds, the radio it still working. The only way to start the phone is to remove the battery and put it again.

Please give me a solution. Thanks,Chris
