BananaOS v3.0.308 is built from the latest Nezha EU HyperOS 3.1 firmware, bringing Android 16 features along with Xiaomi’s newest interface improvements, updated system applications, and enhanced AI capabilities.
Raikiri Kernel
The ROM ships with the Raikiri Kernel, offering improved performance, better thermal management, faster boot times, and smoother daily operation.

These optimizations make the ROM suitable for both everyday use and demanding workloads such as gaming or multitasking.

Built-in Root Management Tools
During the first boot, the ROM automatically installs:

- MT Manager
These utilities simplify advanced device management for experienced users.
Enhanced Audio Experience
BananaOS includes audio optimizations that improve sound quality when paired with premium wireless earbuds, providing clearer output and a more immersive listening experience.
Unlimited Google Photos Storage
The ROM enables unlimited Google Photos storage, allowing users to back up their photos without counting against their available cloud storage quota. Users should always ensure their usage complies with Google’s current terms and policies.
