What’s New?
One of the major highlights of this release is the inclusion of Leica Camera 6.0, bringing Xiaomi’s latest Leica-inspired camera interface and updated photography features to the POCO F3. Users can expect a familiar camera experience similar to newer Xiaomi devices.
The ROM ships with the FakeDreamer Kernel by default, offering a balance between smooth performance, stability, and efficient resource management for everyday use.
Another welcome addition is OrangeFox Recovery, which comes pre-installed, making future updates, backups, and maintenance easier for users who regularly flash custom ROMs.
ZKOS v3.0.5 is based on the POCO F5 firmware, allowing Alioth users to experience software optimizations and newer HyperOS components adapted from newer Xiaomi hardware.
The system also utilizes EXT4 Read-Only (RO) implementation to improve filesystem reliability and maintain system integrity during normal operation.
Performance & Stability
According to the developer, the ROM has been designed to provide a smooth and stable Android 15 experience for daily use. Since this is the first public port, users are encouraged to share feedback to help improve future releases.
The developer notes that the ROM may feel slightly slow during its initial boot. This is normal, as Android performs background optimization, application indexing, and cache generation after installation. Users are advised to allow the ROM approximately 3 to 4 hours to fully settle before evaluating its performance.
With continued usage, the system is expected to become even smoother as optimization completes.
