回答“s7 Screen split into half”My answer is too late, but I just had this problem last week. Here is what I did and it worked as a charm. First I have Samsung Galaxy S7 that I love very much. The upper 1/3 is lighted and lower 2/3 dark but responsive. Solution: I did a hard reset through Safety Mode but that didn’t help. I went to setting, Display, Always on and disabled it. The clock will disappeared when the phone goes to sleeps so did the problem. I am not sure if factory reset is necessary or not but you can disable Always on first and see. Hope that will help.
