Hello,
During a call, I'll get a sudden very loud squeal that sounds like a fax machine. To say that it hurts the eardrums is mild. Why would the phone suddenly start to do this? It doesn't always do this, it's sporadic. AT&T pinged a diagnostic and could find nothing wrong on their end. Could it be the battery? Have been using this device for a couple of years without incident.
