I followed the guide to change display with frame. Now I notice that my phone has problems to receive gsm signal, above all when it’s indoor. Looking the old frame, I see that there are some little pieces of conductive tapes in precise points
Maybe thes points are useful to connect motherboard to ground?
Bu iyi bir soru mu?

Static electricity can cause bad signals with antenna’s so maybe try to buy some conductive tapes and placing them on these points to get that charge out of there. It should be worth the try
Bu yanıt yardımcı oldu mu?
thanks for answer.
i tried to put some conductive pads, but signal is still weak.
If I stay indoor far from window, phone can’t transfer datas by 3g/4g even if signal indicator is good. I see that indoor phone is not able to work by 4g.
If I stay outdoor, phone works perfectly (also by 4g).
It seems that antenna doesn’t have enough power.
I noticed also that the weight of 10kg falled nera sim holder on the display where maybe there is gsm module of mainboard.
