The side keys on your phone do a lot of work every day. They wake the screen, lock the phone and turn the volume up or down. When those buttons stop responding, this flex cable is the part that carries the signal from the keys to the board, so replacing it brings the buttons back to life.
This is a power and volume button flex cable made for the vivo S12, model V2162A. It combines both side keys on one strip, so you replace them together.
What this vivo S12 V2162A flex cable does inside the phone
The flex cable links the power button and the volume button to the main board. Press a key and the cable sends that press through to the phone. If a key feels stuck, does nothing, or only works some of the time, a faulty flex is a likely cause.
- Fits the vivo S12 V2162A
- Covers both the power button and the volume button
- Supplied as one flex cable
The flex is a thin ribbon, so take care when you lift the connector and seat the new cable. Check that the cable sits flat and the connector clicks into place before you close the phone.
