Overview
What this part is
The power and volume keys on the Xiaomi Redmi A3 press against small switches on a thin flex cable inside the frame. A drop, liquid or wear can break a switch or the cable, so the buttons stop working or act on their own.
This flex carries the power and volume switches. If the plastic or metal button caps themselves are missing or broken, those are a separate part.

FAQ
Frequently asked questions
Will this fit my Redmi A3?
Yes, if Settings › About phone shows Redmi A3. It does not fit the Redmi A3x, Redmi A2.
Does it fit the Redmi A3x?
This flex is listed for the Redmi A3. Compare your old flex with the photos if you have a Redmi A3x.
Will it fix a button cap that has fallen off?
No. This flex holds the switches under the buttons. A missing or broken button cap is a separate part.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality flex cable made to fit the Xiaomi Redmi A3, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back cover has to be heated and lifted, the battery must be disconnected, and the flex is thin and easy to tear.
