The Nexus 4 and Nexus 10 will launch with Android 4.2, with other Nexus devices receiving updates soon after. What's new?
The Verge has a full list of what's changed in the new release, namely:
- Photo Sphere panorama photos
- Gesture typing on the keyboard
- Lockscreen improvements, including widget support and the ability to swipe directly to camera
- Expandable notifications with that let you take actions directly
- Message zooming in Gmail with the ability to reflow text automatically
- Daydream screensavers
- Accessibility improvements: triple-tap to magnify the entire screen, pan and zoom with two fingers. Speech output and Gesture Mode navigation for blind users.
- Miracast support for wireless display sharing
- Google Now can use Gmail as a data source for new cards, including improved flight tracker, hotel and restaurant reservations, movie and music recommendations. Photo Spot card recommends interesting places to take photos based on your location.
Photo Sphere panorama photos are street view style images that can be navigated around - pretty neat. Gesture typing is Swype / Swiftkey Flow like functionality and given the popularity of the former, it's certain to be a welcome addition to the base OS. I think the lockscreen improvements are particularly welcome (i'm interested to see if the widgets are display only though rather than interactive, I hope so!).
We've all seen the Gmail improvements already in the leaked APK and aside from some new sources for Now, the biggest addition is Miracast support. Soon to be integrated into TVs (and available via plug in boxes), this allows content to be streamed directly from your device to your TV... Airplay for everyone!
Cue the constant refreshing of device updates, AOSP and stock image pages... :)
