Product Description
Replacement power button for the Samsung Galaxy M31, supplied in red. It suits an M31 that will not switch on or off properly because the power key has stopped working or sticks in its housing.
Keep screws in order if you are fitting it to the M31 yourself, and check the button works before you seal the phone. If it still fails, the M31 fault may lie elsewhere on the board. If the phone still misbehaves, have the board checked before buying further parts.
Key Features & Highlights
Compatibility
- Samsung Galaxy M31 – SM-M315
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 M31 (SM-M315) only.
- Colour: red. Other M31 power button colours have their own listings.
- This listing names a red power button. Contact us to confirm whether it is a button key, a flex cable or both 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.
Frequently Asked Questions
Which phone does this fit?
It is listed for the Samsung Galaxy M31 (SM-M315). Check the model code on your Samsung Galaxy M31 matches before ordering.
How do I check my Samsung Galaxy M31 model number?
Your Samsung Galaxy M31 shows its model number under Settings › About phone. Compare it with the code in this listing, SM-M315, before buying.
Which button does it cover?
It is the red power button for the Samsung Galaxy M31; this listing does not name the volume buttons.
My Samsung Galaxy M31 power button stopped working after a drop. Could this be the cause?
Yes, that is a common cause. A fall can loosen or damage the power button on a Samsung Galaxy M31, and spills can corrode the parts behind it. Rule out a stuck case or dirt first, and if the problem remains after replacement the Samsung Galaxy M31 fault may be on the main board.
How hard is it to fit on the Samsung Galaxy M31, and does the phone need opening?
On the Samsung Galaxy M31 the power button is fitted inside the phone, so the screen or back cover usually has to come off. A repair professional is the safest option, and the button should be tested on the Samsung Galaxy M31 before it is sealed.
