Lenovo's Android Marshmallow release roadmap leaked; K3 Note, Vibe X3 first in line to get update

Last month, Lenovo revealed the list of devices eligible for Android Marshmallow, but refrained from disclosing the specific time-frame of the firmware roll-out process.

Now, a snapshot of Lenovo's internal meeting has surfaced on Weibo, wherein the company's mobile division executive is seen doing a presentation on Android Marshmallow release schedules of 12 Lenovo smartphone models.
