Overview
What this part is
The power and volume keys on the Xiaomi Redmi 9C / Redmi 9A 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. It fits both the Redmi 9C and Redmi 9A.

FAQ
Frequently asked questions
Will this fit my Redmi 9C?
Yes, if Settings › About phone shows Redmi 9C. It does not fit the Redmi 9, Redmi 9T.
Does it fit the Redmi 9A?
Yes. This flex fits both the Redmi 9C and the Redmi 9A.
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 9C / Redmi 9A, 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.
