Android's Smart Lock Won't Ask You For a Password Until You Set Your Phone Down

Nothing confronts you with how addicted you are to your phone more than constantly taking it out of your pocket and entering your passcode over and over again to unlock. But without fanfare, Google is releasing an Android update that might solve the problem: a "smart lock" that can figure out if your phone has been set down since the last time you unlocked it. As long as it stays on your person, you won't need to re-enter your password.
