Screen off detection triggered by short press instead of double press

[NBA613]

With the screen off detection turned on, the action (DND mode) is triggered by one short press (volume key) instead of double press, as configured. This issue occurs only with screen off (with screen on, only double tap triggers action, correctly as configured). I would note that this issue doesn't occur when set to long press. In other words, when configured to long press, the action is correctly only triggered by long press even while the screen is off.
