Windows 10 Mobile Redstone Builds under internal testing have some new features to show off. The Build we are talking about here is the Build 14306 (Thanks Roman) of which, some screenshots have been leaked and they reveal “Audio Routing” feature options in settings. As can be seen in the screenshots above,

  • Audio Routing can be set as automatic, Bluetooth and Phone speaker from options
  • It is now possible to turn the call on the speaker just by moving the phone from your ear.

It is not known whether Microsoft will push Build 14306 next but we can expect upcoming Insider build to bring these features.
