Signal flex or antenna fault: how to tell
If the Galaxy S20 shows low signal bars in areas where other phones work well, drops calls or loses mobile data after a drop or screen or battery repair, the signal flex is a common cause. It is a thin cable that is easy to damage or leave unclipped during a repair. Try a different SIM card first to rule out a network fault. If the problem stays, replacing this cable is a quick, low-cost fix that restores the antenna path between the main board and the lower board.
