CyanogenMod 12.1 to bring Android 5.1 update to Xiaomi Redmi Note 4G: Screenshot reveals OmniROM build under testing Xiaomi

Xiaomi is far from releasing any official Lollipop updates to its non-flagship devices including the Xiaomi Redmi Note 4G, while the industrious CyanogenMod (CM) team has been reportedly busy testing an early build of OmniROM ahead of its CyanogenMod 12.1 release for the budget smartphone.

Xiaomi is unlikely to develop its MIUI firmware for Android 5.1 support anytime soon owing to technical constraints. On the contrary, CyanogenMod has overtaken it in terms of popularity and accessibility, thanks to its pure stock Android-based UI and timely updates from the CM team.
