Using SnapGrab, you will be able to take screenshots using an overlay that fires Android’s MediaCapture intents that are undetected by many common applications. Simply start the overlay service within the app, then press the floating screen shot button.
After capturing screenshots, open the app and decide to either delete the capture or export it to the android gallery.
This is solely a MediaProjection screenshot tool that does not interact with any other services other than its own.
