Ive been through 2 lg volts and both of them had the same calling problems. Most of the time when the phone is getting called the phone call is not received and the other person tell me it rings 2 or 3 times and goes to voicemail but i never receive the call. Another problem is when making a call it takes aproximitely 10 to 15 seconds for the call to connect and the timer to start counting call time. I also noticed that the signal bars disapear when you tap to make the call and reapear when it finally does connect. When i went to radio shak the employee there told me they had the same phone and i asked them about those issues and they said they were having the 2nd issue i mentioned. The problem has been occurring since both phones came out of the box.
