Fixing Dead Power and Volume Buttons on the Vivo X21s
This is a replacement flex cable that carries signals from the power button and volume button on the Vivo X21s. It is the ribbon-style part that sits under the side keys of the phone.
When the side keys stop registering presses, or only work some of the time, the flex cable is often the cause. Swapping it in can bring back normal power on, screen lock and volume control.
Fits this model:

The product data states the cable is a complete fit and works as a replacement for the power and volume button flex. Use it to replace the old cable on your X21s and get your side keys working again.
