What’s New in Project Infinity X v3.12?
This release focuses on updating the ROM to the latest Infinity X source while ensuring stability and long-term reliability.
Updated to Project Infinity X 3.12
The device has been updated to the latest Project Infinity X v3.12 base.
While the maintainer has not published a detailed list of framework commits, this update incorporates the latest upstream improvements available in the Project Infinity X source. These typically include bug fixes, framework refinements, performance optimizations, and stability enhancements accumulated since the previous release.
Android 16 QPR2
This build is based on Android 16 QPR2 (Quarterly Platform Release 2).
QPR releases generally introduce platform-level improvements beyond monthly security updates, including framework optimizations, bug fixes, and reliability improvements that contribute to a smoother overall user experience.

This provides users with a modern camera application that offers an enhanced photography experience without requiring separate installation after flashing the ROM.
Dolby Atmos Support
Dolby Atmos is included by default, delivering richer sound output for music, movies, and gaming. The integrated audio enhancements help improve clarity, surround effects, and overall listening quality across supported audio devices.

Installation Notes
Before installing Project Infinity X v3.12, keep the following recommendations in mind:
- Based on Android 16 QPR2
- Includes the July 2026 Security Patch
- Dirty flashing over Project Infinity X v3.11 is supported
- Leica Camera and Dolby Atmos are included by default
- Use the recommended firmware version specified by the maintainer
- Import a valid keybox if Play Integrity support is required
- Always create a complete backup before flashing any custom ROM
- Report issues with proper logs to help developers diagnose problems efficiently
Why This Is an End-of-Life (EOL) Build
The maintainer has marked this release as an End of Life (EOL) build. This means it serves as the final planned update for the current Project Infinity X release cycle on the POCO F3.
An EOL designation does not mean the ROM is unstable or unsupported immediately. Instead, it indicates that future feature updates for this branch are not expected, and development effort will likely shift toward newer Android versions or future Project Infinity X releases.
For users seeking a stable long-term ROM, EOL builds are often among the most polished because they include the accumulated fixes and refinements from the entire development cycle.
