Overview
What this part is
Inside the Xiaomi Poco F4 GT, the power and volume buttons press on small switches mounted on a thin flex cable along the side of the frame. Drops, wear and moisture can crack the flex or wear out a switch, so a button stops clicking or does nothing.
This part replaces that flex cable. The same flex is used in the Redmi K50 Gaming. It does not include the outer button caps, which usually stay in the frame. If the power button also holds a fingerprint sensor on your phone, compare the old part with the photos before fitting.

How to check your model
Open Settings › About phone. The device name should read POCO F4 GT. The model number is shown under Settings › About phone › All specs. Compare your old part with the photos before fitting.
The Poco F4 GT is a gaming phone with magnetic pop-up shoulder triggers. The standard Poco F4 does not have these triggers.
Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Warm the Xiaomi Poco F4 GT back cover to soften the adhesive and lift it off slowly.
- Disconnect the battery before touching any other connector.
- Unplug and carefully peel the old button flex away from the side of the frame.
- Fit the new flex in the same position so each switch lines up under its button.
- Reconnect the battery, test power and both volume buttons, then close the phone.
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 POCO F4 GT?
Yes, if Settings › About phone shows POCO F4 GT. It does not fit the standard Poco F4, Poco F3 GT or Poco F5.
Does it fit the standard Poco F4?
No. The standard Poco F4 is a different phone with a different button flex. This part is for the Poco F4 GT and Redmi K50 Gaming only.
Does it include the button caps?
No. This is the flex cable with the switches. The outer button caps normally stay in the phone and are reused.
Is it made by Xiaomi?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the Xiaomi Poco F4 GT, and it is tested before dispatch.
Should I fit it myself?
We recommend professional installation. The back cover is glued on and needs heat to remove, and the battery must be disconnected first.
