Frequently Asked Questions (FAQs)​

Which phone uses the codename “frost”?​

Are these ROMs Android 12 or 13?​

The V13.0.x.x builds for POCO C40 are MIUI 13 releases based on Android 11.0, not Android 12 or 13.

Does V13.0.26.0.RGFMIXM include specific bug fixes?​

Public firmware pages for V13.0.26.0 highlight stability and security patch improvements rather than detailed per‑bug changelog entries.
