Signal flex or antenna fault: how to tell
If the Galaxy S23 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.

Frequently asked questions
Does this fit the Galaxy S23+?
No. The S23+ SM-S916B has its own signal flex, which we list separately.
Will it fix Bluetooth drop-outs?
It can, if the cable is the cause, as it carries Bluetooth and Wi-Fi signals as well as mobile.
Is fitting it difficult?
It is one of the simpler S23 repairs. Remove the back glass and mid-frame cover, disconnect the battery and swap the cable.
How fast will it ship?
Orders before 4pm, Monday to Friday, leave Manchester the same day.
