When moving my arm in bed at night, quite often the Vivosmart 5 display lights up, which can wake me up.
I have set up Sleep Settings, Normal Bed Time and Wake Time.
I also have got Settings -> Appearance -> Display Options ->Gesture -> On
I think the Gesture is why the screen lights up, but not sure.
If so, the software developers can surely make it so that 'Gesture' wake is disabled during sleeping hours.
