So on the way home today, I get a call (actually two) from someone at work. When I answer, I cannot hear anything - yet the call continues until the calling party hangs up.
I then return the call. I can't hear ringing or answering.. and the other person hangs up eventually.
So, after a couple of calls to my wife, I realize when I make a call or get one - the phone defaults to headset mode. Which is why I cannot hear anything. When I click on speaker - it works fine. I have Bluetooth turned off - so I have no idea why this would have ever happened.
The Sprint store told me I need to hard reboot. Before I do that, I would love to open it up to the board to see if anyone else has had the problem or can help!
