just a doubt..can doze mode used to wake device?

doze mode always listening to motion sensor even if display is off or deep sleep.. can we use it for waking the device if we pick up.. some apps currently gets it done.. but with wakelocks.. this will be awesome if we can use it without battery drain

am no developer, no idea about how Android internally works.. just got a thought and asked about possibilities.
sorry for my English

thank you

"Double tap to wake" feature

On any s4 mini android 5.1 ROMs such as CM12.1 is there the "double tap to wake" feature since this phone has a SuperAMOLED screen?
