Hi,
I just replaced a cracked display. Unfortunately after putting all back together, the wifi is just working when standing 1-5 meters away from the router.
I also tried to replace the Wifi antenna at the bottom of the iPhone, some of the EMI clips to the display assembly went off. The antenna cable is fitted in properly. I dont know what else I can check.
I have this wifi problem on 2 of my iPhones.
Help would be appreciated very much.
