Chosen Solution
Hi, My iPhone 6 suddenly developed signal issues recently regarding both WiFi and 3G/4G connections. I am aware that there is a relatively common issue with the WiFi antenna flex cable - Wifi signal drops unless I stand right by the router! - Could this cause issues with cell data connections as well as WiFi? Many thanks, Duncan
Yes that is possible. You don’t say much about the history of your device and that is the most important thing to give when you ask people who don’t have access to your phone for repair advice. The related IC’s could go bad but that is pretty rare. When things fail, it is usually related to drops, water damage, excess heat, bending/flexing etc. So if you recently dropped your phone or it happens often enough, then the antenna flexes, may be partially or completely disconnected. Open you phone, following this guideiPhone 6 Logic Board Replacement, and check all the connections. Be very careful as the flexes are delicate and keep track of which screw goes where.
I wonder if anyone else has a possible solution for this? I have checked that all connections are good but that doesn’t seem to have fixed it. Thanks!
