Waking device more reliable with A/B than sleep button?

Often I find that it takes repeated presses of the sleep button to wake the device. I have more luck if I do a long initial press.

But, pressing A/B seems to start the unlock process more reliably?

I seem to remember this has been reported/discussed before on old tracker and Discord

Hey Matt,

Is this an issue of pressing the Sleep button 2x and you only get one eye open? Or are you pressing it once, and it never does the transition animation?

I press it once and it never does the transition animation; it just stays on the clock screen.

If I do multiple short presses nothing happens.

If I do a longer initial press that can sometimes cause a subsequent press to start the transition.

Whereas A/B start the transition on first press seemingly every time.
