Overview
What this part is
On the Galaxy A56, the power and volume keys sit in a raised area on the right side of the frame. Behind them, a flex cable carries the switch contacts to the main board. Wear, impact or liquid can damage those contacts.
This part replaces that internal flex cable. The button caps themselves are part of the frame and are not included.

The A55 and A57 use different flex cables, even though the phones look similar.
Professional installation
How a technician fits this part
- Power off and remove the SIM tray.
- Heat the back evenly and lift it away.
- Unscrew the internal cover and disconnect the battery.
- Disconnect and remove the old button flex cable.
- Fit the new flex behind the keys and connect it to the board.

Check that the part matches the device before fitting it or removing any adhesive backing. Once a part has been fitted, it cannot be returned for a change of mind. Faulty parts are always covered.
FAQ
Frequently asked questions
Will this fit my Galaxy A56?
Yes, if Settings › About phone shows SM-A566B.
Does it fit the Galaxy A55 or A57?
No. Both use different side key flex cables.
The key is physically loose. Will this help?
This cable fixes the electrical contact behind the key. A missing or broken button cap is a separate frame part.
Is it made by Samsung?
No. It is a brand new, OEM-quality flex cable made to fit the Galaxy A56, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back is glued and the battery must be disconnected safely before any repair.
How quickly will it arrive?
Orders placed before 4pm on a working day are dispatched the same day from Manchester by Royal Mail Tracked. Delivery is free on UK orders from £5.
