Microsoft is introducing a new beta app for recent Lumia smartphones that lets you perform some key actions without touching the screen.
For example you can answer a ringing phone by holding it to your ear, switch to speakerphone by placing the phone face up on a table, or mute the microphone by placing it face down on a flat surface.
The new Gestures Beta app uses the accelerometer and proximity sensors in supported phones to recognize where the phone is. Microsoft plans to add support for more gestures in the future, possibly letting you interact with your phone without touching it at all (something you can already do on some phones from Motorola, Samsung, and others).
The app currently supports the Lumia 535, Lumia 730, Lumia 735, and Lumia 830. There’s limited support for the Lumia 530, 630, and 635 as well.
Microsoft is also updating the Glance screen to let you view your lock screen wallpaper.
