Screen Grab

This app has the following features and description:
- allows you to do screenshot with on-screen floating button.
- eliminates the need to recall what physical button combination you need to remember to be able to get a screenshot.
- allows you to drag the floating button anywhere on the screen to uncover whatever is behind it you need to see.
- floating button has its counter to be able to indicate whether the screenshot was successful or not. Counter turns red for a few seconds before turning normal font.
- floating button disappear at the time as it is pressed so that it would not be captured on the resulting image.
- saves screenshot as PNG image on your gallery.
- allows you to hide or end the app by dragging the floating button all the way to the top side of the screen.

Please note that Photo Gallery is not instantaneously updated upon screen grab. You may want to look into My Files or File Manager if you have these apps installed.
