Hi I have a S7 that will only detect the sim once, after I restart it it will not see the sim. I have flashed heaps of different firmware if I leave the sim in it works fine for days. When I restart the the phone at anytime it will not recognize the sim. Even after a clean install with no apps it behaves the same . The sim works fine in all other phones I have. It's driving me a bit crazy. Any hints would be much appreciated.
