Pixel 6 pro, Verizon, unlocked, Tap Tap 1.0.1
Battery Optimisation enabled, Low Power Mode disabled, the screen off gate disabled.
Double Tap Actions: wake or lock the phone, No Triple Tap Actions.
It can work properly (wake or sleep the phone) when the screen is off in a few minutes.
But it can't wake the phone with double tap when the screen is off after ten minutes, whatever Tensor Low Power Mode and Feedback setting Wake Device and the statusbar notification is enabled or not.
BUG:
When I double tap a point at the bottom right of the screen (it is not fixed and not the edge or corner), the screen also can be off. Whenever pressing the key on the right of keyboard, the screen often suddenly turned off, which made me very troublesome. If I remove the lock double tap action, the bug will be gone.
