Today I was texting my best friend and I sent her a picture. As soon as my 4G icon came on, my phone started making a very low static sound. (For those of you that don't know what that is, watch this TV Static effect - YouTube ) The sound went on for about three seconds. Then my 4G icon disappeared and the text message failed to send. What could've happened? This has never happened before on any previous devices and it hasn't occurred once after this instance.
