Nvidia has unleashed a torrent of firmware updates for all of its Shield devices. Buried within each update are security updates and minor changes. The next time owners wake up each device, they should be prompted to download and install the updates.
The Shield Tablet is the only device that explicitly gets a fix for the Stagefright vulnerability, perhaps because it's the only Shield with cellular connectivity as an option. Software upgrade version 3.1.1 includes unspecified stability and performance improvements, alongside system-wide optimizations targeted at battery life and Netflix playback. This update also includes a firmware update for the Shield wireless controller.
The release notes for the Shield Android TV software upgrade version 1.4 only mention that the firmware optimizes the device for newly-released apps and games. The list includes the apps for FXNow, Fox Sports Go, CBS Sports and CBS News, along with all the games that arrived in August. We have long memories, so we tested out elevated access to microSD cards and found that promised fix is included, as well. Similar to the Shield Tablet, the Shield micro-conosle's firmware includes an update for the Shield Wireless Controller, as well.
Finally, the Shield Portable's software upgrade version 106 includes security updates and changes the behavior of some buttons. The Start/Play button "now behaves the same as in Kit Kat" and the Nvidia logo button now opens the Shield Hub instead of voice search.
