Fixing dead power or volume buttons on the Vivo S1
If the power button won’t turn your Vivo S1 on or off, or the volume keys stop changing the sound, the flex cable that carries those buttons is often the culprit. This replacement cable carries both the power and volume button signals on one strip, so you replace them together.
The cable is made for the Vivo S1. It fits the side-button assembly on that model and nothing else, so check your phone model before you order.
- Vivo S1
- Power button and volume button flex cable (one strip)
Use this part when the side keys feel stuck, respond only some of the time, or have stopped working altogether. Replacing the flex gives the buttons a fresh connection to the board.
