Phone is cutting in and out during call.

[AC Question]

Since the latest update (5.0.1) my HTC One M8 cuts in and out during a call. Never had a problem before the update. During a call the phone will cut out (I can't hear them and they can't hear me) for about 10 or 15 second, then start working again for maybe 30 seconds before doing it again. On a 5 minute call it will cut out 4 or 5 times.

I have a 5 bar signal... It cuts in and out using the earpiece, speakerphone and also Bluetooth.

Sometimes I will talk for 10 minutes without a problem then a call to the same # 30 minutes later and it starts cutting out from the start.
