Overview
What this part is
The power and volume buttons on the Galaxy A05 press against small switches on a thin flex cable inside the frame. The keys sit on the right-hand side of the phone. Over time the switches wear out, or the flex tears or corrodes after a drop or liquid damage, and the power and volume buttons stop working.
This flex is listed for model SM-A055F. The model number is in Settings › About phone and on the box. Before ordering, check that the outer keys are not jammed or missing, as this part replaces the internal flex only.

How to check your model

Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back cover edges and lift it off carefully.
- Remove the screws and inner cover, then disconnect the battery before anything else.
- Unclip the old power and volume buttons flex from the side of the frame and unplug it.
- Fit the new flex in the same position, reconnect it and the battery, and test every button before closing.
- Refit the inner cover and screws, then refit the back cover with new adhesive if needed.
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 A05?
Yes, if Settings › About phone shows Galaxy A05. It is listed for model SM-A055F. It is not listed for the Galaxy A05s or Galaxy A04.
Does it fit the Galaxy A05s?
It is not listed for the Galaxy A05s. The A05 and A05s are different phones. Check the model number in Settings › About phone: the A05 starts SM-A055.
Will it fix a broken button cap?
No. This part is the internal flex with the switches. If the outer plastic or metal key is cracked or missing, that needs replacing separately.
Is it made by Samsung?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the Samsung Galaxy A05, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back of the Galaxy A05 has to be removed, the battery must be disconnected safely, and the flex is thin and easy to tear.
