Locating and fixing the hall sensor
So I just went ahead and replacing the entire board that has the charging port, because USB cables would struggle to remain connected if the cable was moved just the slightest. Forgivable for charging overnight, a real pain when trying to charge on the move on in the car.
However I use a flip case on the phone, and have Smart Cover enabled. This uses a hall sensor (small magnet on the case somewhere), and makes it easy to lock (by closing) and turn the screen on (by opening).
Ever since the part replacement, this function has stopped working entirely. And for the life of me, I can’t find any information online about the location of the hall sensor. Is it somewhere on the lower PCB, and wasn’t included in the replacement? WHERE IS THE HALL SENSOR LOCATED?
Also included some images. The two pictures with the red in the middle is the original part. The other two pictures are for the identical part put into my phone. I purchased a few for cheap overseas, and I guess some sellers just have the same suppliers. I did notice that some small chips are missing.
