Hello I don’t really have an issue here… just wondering why my iPhone 6 has no service when it has the right pentolobe screw in and a full signal when that screw is removed. I found it very strange considering i was about to pay 50 $ for a repair. Thank you

Behind the right side bracket that the pentolobe screw goes is the cellular antenna. The screw or bracket is shorting it out when the screw is inserted. Just leave it out and save yourself $50.
