No Signal / GSM Antenna Replacement
My iPhone 6 often has no signal. It sometimes works for a few hours after many restarts but then won't work again for days.
As good as I found out, the GSM Antenna is located in the dock connector part. Is this correct? Will it work if I replace the dock connector part?
P.S. I made sure that nothing else is causing the problem: SIM is changed, software is good, it's not one of the chips on the logic board.
Some people told me to change the Antenna / Flex cable in the upper left of the phone. But isn't this Antenna only for GPS, Bluetooth and Wifi?
Is this a good question?
