This is by far the worst phone I've owned. This is the second v551 I've had because I had the first one replaced for the same problems I'm having now. The problem is that I usually can't hear the caller unless I place them on speakerphone. The problem is intermittent which makes it more frustrating. The second problem is that its difficult to make the connection for charging the battery...I have to cram the cord into the phone before it makes contact. Stay far far away from this phone!!
