Poor celluler signals after reparing iPhone 5s
i repaired iphone 5s and replaced its charging pin . But now it is showing very low and poor network signals. Mostly no signal with the status showing "searching" . I reset its network setting and then reaet and erase all data too. I even chage the sim and try new one. But all made no differnce .
