Lenovo has announced that it has started rolling out the Android Marshmallow update to K4 Note units in India. The announcement came in the form of a tweet from the Chinese company's India subsidiary.
Some of the other Lenovo devices that have received the Marshmallow update in the recent months include the K3 Note, A7000, and Vibe P1. And now you can add the K4 Note to the list. There's, however, no information on what other changes (if any) the K4 Note Marshmallow update includes.
Given that the update has just started rolling out, it might take some before you see an OTA notification on your device. Meanwhile, if you feel impatient, you can manually check for the update by heading to your handset's Settings menu.
