Usually raising your hand to wake up the screen can only last for one second, and then it will turn off immediately. I can’t find the time setting and can’t adjust it.
Solution ,,using macrodroid app
1trigger ,open screen(when the screen opens)
2Task action,Screen saver on (A moon icon in action) …done
very simple ,This way you don’t need to press the power button anymore,This is complete and can adjust the time
