The LTE icon on the S7 started flickering on 6/22/19. Before that happened, I tried to call my husband's S7, and when he answered, the call ended. He tried to call me and when I answered, the call ended. We tried several times to connect, but could not. When I got home, I call my house land line and the same probled occured. I tuerned the phone off and on, and the problem went away.
However, I am left with the LTE icon 'pinging' every few seconds; and a battery that drains much quicker than normal.
I would appreciate any help. And, yes, the phone is up to date with system updates.
