Network carrier AT&T has reportedly released the long awaited Android Marshmallow to flagship LG V10. The new OS update is a little over 1GB in size and has been made available through over-the-air (OTA) to LG V10 in the U.S., Android Central reported.

OTA roll-out process is usually carried out in stages. So it will take some days to reach all corners of the country.

LG V10, which was launched in October 2015, came with Android 5.1.1 Lollipop out-of-the-box. Now, Android Marshmallow will bring the Doze power optimisation feature, an improved "Now on Tap" search option, silent mode added to sound profile, more shortcuts, an intuitive boot security system and performance enhancing tweaks to the LG flagship device.

In addition to Marshmallow features, it also comes with new visually appealing custom LG UX interface. The company has also tweaked the KnockCode screen-unlock system, to make it more secured. Now, users have to tap at least 6 times and use at least 3 different quarters to access the home screen.
