Touchscreen Not Responding

### Affected hardware version

Bangle 2

### Your firmware version

2v22

### The bug

The touchscreen of my device stops working, seemingly at random. Not affected by installing or removing apps. Full reset does not help. No touch even on the bootloader/testing menu when holding down the button.

Function seemingly returns, but with no apparent pattern. Screen is physically undamaged, no cracks or scratches and is clean.
