Overview
What this part is
The Honor 50 Pro uses one flex cable for the power button and the volume up and down buttons. The contacts on this cable wear out with daily use, or crack after a drop. When that happens, the buttons feel normal but do nothing, or only work when pressed hard.
This flex cable replaces the switches behind the buttons. If the outer button caps are missing or bent, those need replacing separately. Restart the phone first to rule out a software fault.

Professional installation
How a technician fits this part
- Power the phone off and remove the SIM tray.
- Open the Honor 50 Pro with the correct method for this model, using gentle heat and a thin opening tool.
- Disconnect the battery before touching any other part.
- Remove the parts covering the side button flex, then peel away the old flex cable carefully.
- Fit the new flex cable in the same position, reconnect it and reconnect the battery.
- Test power, volume up and volume down before closing and sealing 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 Honor 50 Pro?
Yes, if Settings › About phone shows Honor 50 Pro. It is made for this model only and does not fit the Honor 50, Honor 50 Lite or Honor 50 SE.
Does it fit the Honor 50?
No. The Honor 50 uses a different part. Check the model name in Settings › About phone before ordering.
Does it include the button caps?
It is the flex cable with the switches. Check the photos to see exactly what is included. The outer buttons on your phone are normally reused.
Is it made by Honor?
No. It is a brand new, OEM-quality power and volume button flex cable made to fit the Honor 50 Pro, and every part is tested before dispatch.
Should I fit it myself?
We recommend professional installation. Opening the Honor 50 Pro needs heat, the right tools and new adhesive, and the battery must be disconnected safely.
