Overview
What this part is
The power and volume buttons on the OPPO A3x 5G press against small switches on a thin flex cable inside the frame. After a drop, water damage or heavy use, a switch can wear out or the cable can tear, so the button stops working or sticks.
This part replaces that flex cable. It does not include the outer plastic or metal button keys. If the button key itself is missing or broken, you may need that part as well.

How a technician fits this part
- Power the phone off and remove the SIM tray.
- Remove the back cover and the screws holding the inner panels.
- Disconnect the battery before touching any other connector.
- Unplug and lift out the old flex cable, then fit the new one so the switches line up with the button keys.
- Reconnect the battery and test every button before closing.
- Refit the panels, screws and back cover.
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 A3x 5G?
Yes, if Settings › About phone shows OPPO A3x 5G. It does not fit the OPPO A3x 4G, A3, A3 Pro.
Does it fit the OPPO A3x 4G?
The supplier lists this flex cable for the OPPO A3x 5G. If you have the 4G version, compare your old part with the photos before ordering.
Does it include the outer button keys?
No. This is the inner flex cable with the switches. The outer button keys are separate. Keep your old keys if they are not damaged.
Is it made by OPPO?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the OPPO A3x 5G, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back cover has to be removed carefully, the battery must be disconnected first, and small flex cables are easy to damage.
