This is a power and volume button flex cable for the ZTE Blade V40 Smart. It carries the signal from the side keys to the phone’s main board, so both buttons work together on one replacement strip.
What this flex cable does in your ZTE Blade V40 Smart
When the power or volume keys feel dead, stick, or only work some of the time, the flex cable is often the cause. Swapping in a new one brings back the press and response you expect from the side buttons. Your phone can once again wake, lock, and change volume without fuss.
Each unit is a new replacement part. It is designed to replace a broken or unworkable cable and fits the ZTE Blade V40 Smart.
What you get:
- One power and volume button flex cable
- Covers both the power key and the volume keys
Before you start, check that the cable matches your model exactly. The ZTE Blade V40 Smart uses a specific layout, so a match matters for a clean fit.
