I have a very serious issue that cause my wifi doesn't work, I've tried everything like replacing a new wifi antenna and tighten the screw and my wifi just won't turn on ( It still remain like grey button ) because of that I borrowed my friends logic board ( motherboard ) to make sure is my mother board problem or not, and I found it it's my phone casing problem, my wifi is working since I move my logic board to his casing. Any technician here know what's the problem?
