This is my 2nd Samsung Galaxy J3V smart phone and it is having the same problems as the one I returned to the warehouse. It hangs up on me. Sometimes it will disconnect several times on one call. I am holding it carefully so that my face doesn't touch the screen and my fingers don't touch anything but the side of the phone. Before it disconnects, it makes a series of beeps like someone is trying to dial in. Then it disconnects. If I take it outside, that sometimes helps but not all of the time. Very frustrating and I now ask my contacts to email me instead. Anyone else having this problem? Thanks.
