Often, iPad users find themselves tapping a link that opens in a completely separate app – say, a link in Messages to a webpage in Safari or from Facebook to a video in YouTube. Sometime’s it can feel a little cumbersome to get back to what you were doing quickly.
Well, there’s another option in iOS. Whenever a new app is launched from a link – even something you’ve searched for from Spotlight – there will be a small Back button in the top left of the screen, showing the name of the app you just switched from. Simply tap it to return to the previous app.
