Often, iPhone 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. In these cases it can be a little cumbersome to manually switch back to the previous app.
Not anymore! Whenever a new app is launched from a link – even something you’ve searched for from Spotlight – there will be a small < button in the top left of the screen, alongside the name of the previous app. Simply tap it to return to what you were doing.
