All I find is suggestions from a few years ago, so probably outdated or maybe there appeared some better tools in the meantime, there are some apps in the play store but I need something good privacy wise, no training demon, also small battery life impact would be nice

For your unfamiliar with moto gestures I’m talking about are chop for flashlight and twist for camera, they work irrespective of app you’re in or screen being on/off

Also changing songs with volume buttons was nice
