This flex cable carries both the power button and the volume buttons on the ZTE Blade V40 Design. It is a single part that replaces the whole side-key strip, so you do not need to swap the buttons one by one.
Power and volume keys not responding on the ZTE Blade V40 Design
If the power key won’t wake the screen or the volume keys have stopped working, the flex cable underneath is often the cause. Fitting a new one brings back normal control of both keys in a single replacement.
- Model: ZTE Blade V40 Design
- Part: Power button and volume button flex cable
- Supplied as one flex cable, ready to fit
The cable is a new part that replaces the broken or unresponsive original. Because the power and volume keys share this one cable, the replacement covers both at once. Check that the fault is really in the side keys before you order, so you know this is the part you need.
Fitting a side-key flex cable means lifting the cover and working around the board. Take care to line up the connector squarely before you press it down.
