What this antenna does?
I have iPhone 6 and its WiFi and GSM signal reception is poor. WiFi works within just 5m range of router. GSM signal sometime works on different locations and sometime doesn't. I opened my iPhone and found that its antenna.
It is broken from its connector, is this a reason it is giving such poor reception?
I am going to give my iPhone to local repair shop who will fix this antenna
Is this a good question?
