Why do I have no signal on my iPhone?
After replacing the lighting connector in my iPhone 5s successfully and finding that everything was working I discovered that I had no signal anywhere. After a few days I did get 1 bar and a 3G connection but nothing more than one bar very ocasionally ever since.
I did find one part whilst taking apart my iPhone that fell out and was a tiny shaped piece of metal. I beleve that this could be some sort of radio shield but I cannot find any reference to this part anywhere even after looking through the 5s teardown.
- I have checked all connections to the logic board and hard rebooting the phone both with and without the sim card in.
- I have checked the Time and Date are set correctly and that the sim works in another iPhone (4)
(Width of part ~ 3mm)
Any insight on the problem would be greatly appreciated.
