Wifi ground broken from logic board.
This question is archived. No new answers are allowed, and only the question's owner may edit it.
My wifi signal is weak since I dropped my iPhone last week.
After searching the web for sollutions I checked the screw and silver metal tab on top of the wifi antenna but they were in the right place. When I lifted the wifi antenna I found that the wifi ground connector on the logic board was broken.
I don't have a camera (beside my iPhone) to take a picture, but the following image explains my problem: broken logic board
Is there any way I can shortcut the wifi ground or something like that?
