Overview
What this part is
Inside the Xiaomi 12T Pro, the side buttons press on small switches mounted on a thin flex cable. Drops, bending and moisture can crack the flex or wear out the switch, so the keys stop responding or act on their own.
If the physical keys still click but nothing happens, the flex cable is the usual fault. Restart the phone first to rule out a software problem. On many Xiaomi models the power key also holds the side fingerprint sensor, so compare your old part with the photos before fitting.

Before you order

How to check your model
Open Settings › About phone. The device name should read 12T Pro. The model number (22081212UG) is shown in Settings › About phone › Detailed info and specs and on the box.
The Xiaomi 12T Pro has a 6.67-inch AMOLED screen and a 200MP main camera. The standard 12T looks very similar, so check the model name.
Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the back glass to soften the adhesive and lift it off carefully.
- Remove the screws and covers, then disconnect the battery.
- Unclip and peel out the old button flex from the side of the frame.
- Fit the new flex in the same position and press it flat against the frame.
- Reconnect the battery, test every button, then refit the back glass with new adhesive.
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 12T Pro?
Yes, if Settings › About phone shows 12T Pro (model 22081212UG).
Does it fit the Xiaomi 12T?
The 12T and 12T Pro share the same body, but this flex is listed for the 12T Pro. Compare your old part with the photos before ordering.
How do I know it is the flex and not the button?
If the plastic key still clicks normally but the phone does not respond, the flex is the usual fault. If the key is missing or cracked, you need the key itself.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality flex cable made to fit the Xiaomi 12T Pro, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The 12T Pro must be opened with heat, the battery disconnected, and the thin flex handled with care.
