The announcement was made by Bill Yi from Google, on Android Building group, saying, "Today we pushed the kernel source for the Android One device family. The kernel source can be found on the android-msm-sprout-3.4-kitkat-mr2 branch in the kernel/msm project. It's also tagged with 'android-4.4.4_r3'."
Google shortly after shifted the the kernel source code from the Kernel tree for Qualcomm chipsets, to what appears to be a newly-created Kernel tree for MediaTek with just one branch. Bill updated the Android Building group post, saying, "The kernel source can be found on the android-mediatek-sprout-3.4-kitkat-mr2 branch in the kernel/mediatek project."
The three Android One smartphones - Karbonn Sparkle V, Micromax Canvas A1, and Spice Dream Uno - come with near identical specifications and use the same Android builds. Android Police notes the release of the kernel source comes with a fix for a minor gyroscope bug.
Google has announced that the Android One smartphones will be among the first to get the much-awaited Android L update.
