  • What version of Android is this? – user186920 Oct 22 '16 at 18:12
  • It's Marshmallow. – dev gr Oct 22 '16 at 18:19
  • Interesting, because I've never seen that lock/unlock button before. – user186920 Oct 22 '16 at 18:19

If you lock an app in recents and click on tap to clear, it will stay in recents. Apps not locked will be cleared (that kills all the running apps without the need to kill each one separately)

  • I thought the same, but after you answer I realized it's bit different behaviour wise. The moment you lock an app and press the clear button, it clears all the app at that moment but when next time you press the recent apps button you will find locked app there.

    Exactly. It is to ensure that locked apps are always kept alive – beeshyams Oct 22 '16 at 17:22
