I saw my partner pressing the home and power button several times and then use different passwords swipes. I wonder if there is a way to possibly maybe have two launchers or an app using those techniques to hide stuff. When I approach her at one time she did a swipe on her phone that clearly change from one screen to another and then I saw the screen she use to cover it up rather than pressing the multiwindow button to switch screens. This is what caught my attention on this. Can anyone comment if this is?
