Phone occasioally does not ring but registers as a missed call or goes to voicemail?
i have the same problem
no i have the same problem, occasionally incoming calls will go straight to voicemail and not show up as a missed call. don't know what causes this.
Hmm... I think this is just a case of not noticing the phone. Increase ring volume and change to a very loud ringtone so everytime you receive a call, you will surely hear it.
