Phone parts are delicate. We recommend fitting by a qualified repair technician.

Test the part before final installation, before any adhesive or seal is applied. Parts with adhesive applied can’t be returned for change of mind.

Product Description

✦ For Samsung Galaxy A40 (SM-A405) Power and Volume Button Flex Cable Ribbon

Replacement power and volume button flex cable for the Samsung Galaxy A40 (A405). Sitting behind the side keys, it is the part to change when the Samsung Galaxy A40 power button or volume rocker no longer registers a press.

The Samsung Galaxy A40 power and volume controls are handled by this one flex cable, so you do not need separate parts for each button.

A repair technician can usually confirm on the bench whether the Samsung Galaxy A40 flex is at fault before a part is bought.

Compatibility

  • Samsung Galaxy A40 (A405)

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.

⚠️ Important — Please Read Before Purchase
  • Listed for the Samsung Galaxy A40 (A405) only.
  • Professional installation is recommended for this part.
  • Button flex cables are thin, so handle the Samsung Galaxy A40 part by its edges and avoid creasing it during fitting.
  • 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.
Your statutory rights under the Consumer Rights Act 2015 remain unaffected for faulty or not-as-described items.

Frequently Asked Questions

Which phone does this fit?

The Samsung Galaxy A40 (A405) is the phone named in this listing. Make sure yours is the same Samsung Galaxy A40 version first.

How do I check my Samsung Galaxy A40 model number?

On the Samsung Galaxy A40, open Settings › About phone and read the model number, which should show SM-A405. Match it to the model named in this listing before you order.

Which buttons does it cover?

This flex is listed for the power and volume buttons on the Samsung Galaxy A40, handled together on one flex cable.

My Samsung Galaxy A40 button stopped working after a drop. Could this flex be the cause?

Yes, it is a common cause. A hard knock or moisture can tear or corrode the flex in a Samsung Galaxy A40. Check for a tight case or debris first, and if a button still fails after the flex is replaced, the fault on the Samsung Galaxy A40 may sit on the main board.

How hard is it to fit on the Samsung Galaxy A40, and does the phone need opening?

On the Samsung Galaxy A40 this part is inside the frame, so the phone normally needs opening up with the screen or back off. Flex cables are fragile, so professional fitting is a sensible choice for the Samsung Galaxy A40. Test each button before you seal the phone.
