Asus has officially started rolling out the stable Android 16 update, beginning with the Zenfone 12 Ultra. The update follows nearly three months of beta testing, after the company first introduced the Android 16 beta program for the device in August. The move marks an important milestone for Asus users, bringing a refined software experience, essential performance improvements, and expanded customization tools.
The rollout signals Asus’s shift toward faster, more reliable software delivery. Users who participated in the beta program had highlighted several issues, including battery drain and UI inconsistencies, which the company has now addressed in the stable release. The update focuses on improving system stability, fixing long-standing bugs, and enhancing optimization across core tasks.
According to early adopters, the new build delivers smoother animations, better multitasking efficiency, and noticeable improvements in camera processing. Asus has also fine-tuned background processes to reduce lag and improve thermal control, offering a more consistent performance profile during heavy usage.
Android 16 introduces enhanced privacy controls, giving users more transparency and authority over app permissions. The Zenfone 12 Ultra now benefits from more granular location settings, improved notification management, and advanced battery analytics. The update also supports the enhanced predictive back gesture, dynamic theming refinements, and an improved AI-powered interface that adapts more accurately to user habits.
The new build makes changes to multitasking layouts, introducing a cleaner split-screen view and more intuitive window controls. Gamers have noted improved frame rate stability thanks to better memory management and low-latency optimizations, which boost performance in high-demand scenarios.
Asus has also expanded its ecosystem features. The update improves connectivity between Zenfone devices and Asus laptops through enhanced pairing and file-sharing tools, strengthening cross-device integration for productivity-focused users.
With the rollout now underway, Asus is expected to push the Android 16 upgrade to more devices in waves. The Zenfone 12 Ultra is the first to receive the stable build, but models in the Zenfone and ROG Phone lineup are likely to follow soon, depending on regional certification and testing schedules.
For Asus users, the release reflects a major quality-of-life improvement and a renewed focus on long-term software support. As Android 16 becomes available on more devices, Asus aims to offer a more polished, secure, and future-ready mobile experience across its entire portfolio.
