Product Description
This power and volume button flex cable is a replacement for the Samsung Galaxy S24 FE (SM-S721B). It is the flex inside the frame that carries the power button and volume button signals, so it is the part to check when the side buttons on a Samsung Galaxy S24 FE stop responding, stick, or press by themselves after a drop or liquid contact.
One flex serves both the power and the volume controls, which helps when more than one button on the Samsung Galaxy S24 FE has failed.
Remove the case and clear dirt from around the buttons before deciding the flex is at fault. A technician can usually confirm on the bench whether the Samsung Galaxy S24 FE flex is the problem; if you are fitting it yourself, keep screws in order and test each button before the phone is closed up.

Signs Your Power or Volume Button Flex Needs Replacing
- The power or volume button does nothing, or only works when pressed hard.
- Buttons stick, feel loose or trigger on their own.
- The phone restarts, screenshots or changes volume without you pressing anything.
- A button stopped working after a drop or liquid exposure.
- Before replacing, remove the case and check the button is not blocked by dirt or a tight case.
How to Check Your Model Number
On the phone or tablet go to Settings › About phone (or About tablet). The model number starts with SM- (for example SM-A145R). It is also printed on the box the phone came in.
Specifications
- Listed for the Samsung Galaxy S24 FE (SM-S721B) only.
- Professional installation is recommended.
- Contact us to confirm whether physical button keys are supplied before ordering.
- Professional fitting is recommended; button flex cables are thin and tear easily, and the phone usually has to be opened fully.
- Button flex cables are model-specific — check that your device matches the model shown above before ordering.
- Test power, volume and any other buttons on the flex before sealing the phone.
- If a button still fails after fitting, the fault may be on the main board rather than the flex.
- If you are unsure which part you need, contact us with your model number before ordering.
