Microsoft's next Lumia update, Denim, will include a "hey Cortana" command to activate the personal digital assistant automatically. The always listening mode is similar to Google's "OK Google" command, allowing Windows Phone users to activate Cortana even when the phone is on standby. Microsoft announced the new Lumia Denim update on stage at its IFA press event in Berlin today. Denim also includes a number of camera improvements to speed up launching the camera app and capturing photos, and Microsoft is updating the Lumia Camera app to support 4K recording.
Alongside the camera improvements, Lumia Denim also includes updates to Glance Screen to show information from Bing Weather or Bing Health & Fitness with time and date, notifications, and app data. Lumia Denim will ship on the Lumia 830, Lumia 730, and Lumia 735, and then the camera improvements will be made available on the Lumia 930, Lumia 1520, and Lumia Icon. Lumia Denim should start rolling out to all Lumia Windows Phone 8 devices during Q4 2014.
