[ENHANCEMENT] Detect when launched by Samsung > Side Button > Double Press

Please see if FakeStandby can detect that it has been launched by Double Press of the Side Button, and if so, launch FakeStandby's fake stand-by.

On modern Samsung Galaxy devices, there is a setting called Labs > Side Button > Double Press that allows you to select an app to be launched when double-tapping the Power Button (the Side Button).

To change this setting, the user normally presses and holds the Side Button and which gives the Power Off and Restart options, as well as Side Button Settings. Clicking Side Button Settings gives the option to select an app to launch, or to launch the Camera app (default).

Please see if FakeStandby can detect that it has been launched by Double Press of the Side Button, and if so, launch FakeStandby's fake stand-by.

P.S. Also detect if launched by the app Key Mapper, and do the same -- launching into fake stand-by mode, instead of launching the app settings UI.
