For the first time ever, the ROG Phone 5 and ROG Phone 5s are the winners. On Asus’ official forums, the updated software is expected to be available for both models. For both, the updated build is 31.0810.1226.57.
Additionally, you’ll find a new ROG UI and many other upgrades and refinements in the Armory Crate, as well as all the normal Android 12 goodies. Check out the Source links below for the full list. Unfortunately, we can’t post the complete changelog here since it’s so massive—and luckily contains some bug fixes as well.
A few days (or even weeks) may pass before the update is available on all devices, as is customary with software updates. It’s possible to get the updated version directly from the official website, which is linked from the Sources below. The only way to guarantee a successful installation is if you have the proper model number and back up your data as directed before to starting the process.
