The side keys do a lot of work every day. They wake the screen, take screenshots and turn the volume up or down. When they stop responding, the phone gets frustrating fast. This flex cable carries the signal from the power and volume buttons to the board, so swapping it out can bring those keys back to life.
What’s in the vivo Y78+ volume and power button flex cable
This is a single flex cable for the vivo Y78+. It carries both the power button and the volume button on one strip, so you only need the one part for both keys.
- One power and volume button flex cable
- Made for the vivo Y78+ model
The cable is a direct replacement part. It is meant to fit and work the same way as the original strip that came with your phone. If only one of your side keys has stopped working, check the flex first before you buy a new button set, since both keys share this cable.
