Sliding it in the same direction but all the way to the end of the screen you can go back to the start menu. By sliding it upwards you can open the main menu of the app.
From the main menu of the app, you can manage all the files in your Android smartphone. You can view your pictures, documents and videos; but you can also browse YouTube or google or even check the weather.
