Key Features & Highlights
Compatibility
- Samsung Galaxy J3 (2017) – SM-J330
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 J3 (2017) (SM-J330) only.
- 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.

This flex is listed for the power button on the Samsung Galaxy J3 (2017). It is not listed for the volume buttons.
My Samsung Galaxy J3 (2017) button stopped working after a drop. Could this be the cause?
Possibly. A knock or liquid exposure can bend, tear or corrode the flex inside a Samsung Galaxy J3 (2017), and the buttons then stop responding.

If a button still fails with a new part fitted, the Samsung Galaxy J3 (2017) fault may be on the main board.
How hard is it to fit on the Samsung Galaxy J3 (2017), and does the phone need opening?
You will normally need to open the Samsung Galaxy J3 (2017) fully, as the button flex is behind the internal parts. It tears easily, so professional fitting is recommended, and test every button on the Samsung Galaxy J3 (2017) before it is sealed.
