American smartphone maker InFocus has revealed the Android Marshmallow update roll-out roadmap for a couple of its devices in India.

InFocus (on Facebook) has confirmed that the Android Marshmallow update deployment process for M812 and M370 will begin on 31 December, 2015.

InFocus M370 and M812 were launched in India last month. They came with Android 5.1 and 5.0 series Lollipop OS out-of-the-box respectively and by this year-end they will be upgraded to the latest Marshmallow OS.

This is a welcome initiative from InFocus to instill loyalty among the buyers considering the fact that many Tier-1 brands such as Samsung, OnePlus and others are yet to officially announce software update plans for their flagship devices.
