1. Android L's 'personal unlocking'
When Android L, the next version of Google's all-encompassing mobile operating system, hits the streets this fall, it'll pack in a headache-relieving feature dubbed 'personal unlocking.' Personal unlocking takes what it knows about both you and your phone to alleviate the need to enter a security PIN when your phone's in a safe situation. The automatic authentication can be handled several ways: Android L can tell if you're in a trusted location, for instance, or sense your paired Android Wear watch, or even pick up on the sound of your voice. It'll be intriguing to see how this plays out.
