Asus is updating two of its flagship Android phones, the ROG Phone 9 and Zenfone 12 Ultra, to Android 16. The two devices launched with Android 15 in late 2024 and early 2025, respectively, and were some of the final major flagships still waiting to get an upgrade. Google released the Android 16 in June 2025, and said it spent time working with third-party OEMs beforehand to help deliver future Android upgrades quickly.
After a five-month-long wait, Asus ROG Phone 9 and Zenfone 12 Ultra users are starting to receive the Android 16 update. It comes with a version number of 36.0810.1810.43 for both phones, and each update should be around 1GB in size. The Asus ROG Phone 9 update includes more fixes and improvements, per the release notes, which makes sense considering it’s the older device.
Asus warns users that some third-party apps aren’t compatible with Android 16 yet, and recommends they back up their device before applying the update. It also explains the Android 16 update is rolling out in batches, based on device serial number, so it might take a few days for all Asus ROG Phone 9 and Zenfone 12 Ultra users to receive it.
