It's an early Merry Christmas for owners of Shield K1 tablets. Nvidia has released a software update that brings Android 6.0 Marshmallow to this gaming slate. Nvidia runs a mostly-stock version of Android on its devices, with only a couple touches of its own. The release notes cover both stock and Nvidia features alike.
First and foremost, microSD cards can be used as main storage. The operating system will manage the combination automatically. Beware, though—if you want to use your microSD card as internal storage, it'll need to be wiped clean, so take a backup beforehand. The Quick Settings menu is now user-customizable, too. The Settings app now offers centralized management of application permissions, as well as improved monitoring of applications' memory usage.
Speaking of usage, Nvidia says that application' standby power draw should be improved, and that Bluetooth LE scanning is more power-efficient. Google Now can be invoked from the home screen, too. Last but not least, the Camera app's UI has been improved, and users can add "real-time HD Image Effects" to their work. Perfect for taking selfies while gaming. Oh, and Fallout Shelter comes preinstalled. Can't go wrong with that.
