Micromax Canvas A1

Cyanogen has announced official support for Android One devices. CyanogenMod 11 builds based on Android 4.4 KitKat can now be installed on Android One handsets, with an update to Lollipop-based CM12 in the works.

Cyanogen mentioned that the release was significant in a number of ways:

This release represents a few firsts for us. Not only are these the first Android One devices and first official release of CM for these devices, the Android One device is the first ever officially supported Mediatek device. Mediatek (MTK) devices have been notoriously difficult for the developer community to complete fully functional bring-ups, and this marks a milestone in that effort.

There has been a CM11 port available for Android One since October, but that version did not allow for usage of dual-SIM radios or cellular data. Those issues have since been fixed. As there isn't much to differentiate the Android One devices in terms of hardware, Cyanogen is rolling out a unified ROM (with the devices codenamed sprout) that will work on all current-gen hardware: Spice Dream Uno, Karbonn Sparkle V and Micromax's Canvas A1.
