No Service or very weak signal on iPhone 4s
Hi, I was trying to change the cellular antenna that I found out the blue coil and another piece is missing (as you can see in the picture, ignore the red and blue markings). I just want to know, what exactly there parts do and is there any way to bypass them. I have read about the blue coil but I do not know much about the other tiny piece beside it. Anybody knows what it does? please help me, its urgent.
I tried to bridge the blue coil with a piece of wire (the other piece is still missing), the cellular antenna is back but when I trun on 3G it goes back to 1bar network. With 3G off it works just perfect but as soon as I turn 3G on the signal weakens. Any ideas?
Is this a good question?
