GoKawiilAction Notch app turns Android camera cutout into a customizable gesture button
A free Android utility called Action Notch converts a phone's front camera notch into an interactive shortcut, letting users tap, double-tap, or long-press it to trigger actions like screenshots, flashlight toggles, or automation scripts from Tasker and MacroDroid. The app supports more than 50 actions, and a paid pro tier adds extra gestures plus rule-based actions that let a single gesture behave differently depending on context.
