My phonefunctions seems to chrash totally random. There seem to be no obvious reason that the phonefunction seems to quit, particularly when I get incoming calls. I get the message: "com.android.phone has stopped working". The phone rings, but I cannot answer it, and I cannot see who is calling, and not a trace of the call is stored in the log. Sometimes the display turns black, sometimes I cannot make a new outgoing call after this occurs and sometimes I can. The rest of the phones functions seems intact after this occurs. Sometimes it fixes it self, sometimes I have to reboot, and sometimes I have to pull out the battery and restart. Any ideas? Thanks.
