Signal very poor and 3g/ 4g doesn't work in most of time

I have bought a second hand Iphone SE 64gb. I verified it in center of my town and it worked without problems. When I arrived at home signal was very poor, no internet connection. Out of town I have same problems. I bought another sim card, another carrier/ same problem.

I checked everything and it's from my hardware. I think that logic board is the problem. Could you give me informations what to change at it? I don't find on internet any informations also I am sure that is not flex cable. I need some informations how to repair/ what to change on logic board. Thanks!!

Отвечено! Посмотреть ответ У меня та же проблема

@theelitepro_gd really Vinicus, another statement that screams "I don't have any idea of what I'm talking about, I'm just blowing something out my rear".

The likely problem is a lightning dock. After that it would be board level repair. It wouldn't serve you to just get another logic board, as it would be just as costly as a new phone

Thanks! Can you explain me why the lighting dock can be the problem?

из

Sure. The Lightning dock does many things. One of the things is cellular data antennae. That's why I think this is your problem

Ok! Thank you very much!

Curious if this was a fix as I have the same issue and was about to replace the antenna first
