A little circle will appear on your screen at all times, wherever tapped a menu will appear, with different options
This are some of the features One f my favorites is multitasking where I can see on the bottom of the screen all the apps That are still running in the background Enjoy !
A cool thing is that when you do a screenshot The little circle will not appear So I will not interfere with your screenshot
