Samsung released the Z Fold series a few years ago. However, the phone will have some common faults including "Black Screen" "Abnormal Touch" etc. In today's case, REWA LAB fully disassembles a Z Fold 3 which has "No Sound" and "Wi-Fi Grey Out" issues. We successfully fixed it by replacing the hinge flex cable. We believe these kinds of issues are mainly caused by the flex cable breakage. So what are the tips that you need to notice, you are in the right place.
