Google's newest operating system Android 6.0 Marshmallow runs on less than 1 percent of Android devices one month after its release. Android users anticipate having Marshmallow in their devices, but the roll out also depends on smartphone companies, not just Google.

Despite the release on Oct. 5, only 0.3 percent of Android devices are running on the "sweetest, smartest" Android OS to date. According to PC Mag, Android 6.0 Marshmallow first rolled out to Google's Nexus devices, including Nexus Player, Nexus 5, 6, 7 and 9 on Oct. 5. HTC One A9 also got the Marshmallow as the first non-Nexus device to get the latest Android OS.

Apparently, the slow roll out is largely affected by smartphone companies who still tweak the OS according to their preferences, Tech Times reported. While Google is pushing the update to Nexus devices, companies like Samsung and HTC are still customizing the OS.

Google learned about the low number of Marshmallow users via its Play Store app, which also identified other OS versions that Android devices run on. For instance, 25.6 percent run on its predecessor Lollipop, with versions 5.0 and 5.1. About 38 percent, which is the largest percentage of devices, run on KitKat 4.4.

The Jelly Bean OS still has 29 percent of users, Ice Cream Sandwich has 3.3 percent and Gingerbread has 3.8 percent of users. The only OS version that currently has lesser users than the Marshmallow is the really old Froyo 2.2, which has 0.2 percent of users.

Despite the current numbers, tech enthusiasts believe that smartphones, like the Samsung Galaxy series, will start updating to Android 6.0 Marshmallow soon and the numbers will significantly jump to 20 percent.
