Hello. İ have samsund S7 edge and i had lived the same problem. İ solved it how? I'll say u. Firstly, i watched every youtube videos that about this problem, but they did not help me. My cousin said me that u should go from where you got this telephone. I went "world telecom" and i had a warranty about it. Actually they must solved this issue when we got the telephone, but they had forgot it. I went and they solved it just fee minute. I advice u that going to where u got that telephone
