When I have voicemail showing in the notification area (top of the screen) and I pull it down to choose to listen, once it dials, I can hear the voice telling me about new messages and to enter my pin. The problem seems to be when it ask me to enter my pin number, the dialpad blinks and black out after I pick one number and I can't choose another number before the voice will say wrong pin number. Has anyone seen this issue before? Is there a way to stop it from blinking? What is another way to go into the voicemail system? Thnx.
