Google announced its upcoming Android version at Google I/O 2015 in late may. But as it’s done before, Google held off on announcing the full name to build anticipation around the software. The company typically names its software updates alphabetically and after sweets. For example, the most current version of Android is named Lollipop, and the one before that was KitKat. Marshmallow is expected to be released this fall. Google has Offically announced Marshmallow, as the name of Android M.

But while the names are silly, Android is serious business for Google. The software powers more than 80 percent of the world’s smartphones, from manufacturers including Samsung, HTC and Motorola. The software is also a gateway for Google to get people to use the company’s services — like search, maps and video site YouTube — on their phones.

Along with finalizing the name, Google has also released the finished version of its Android 6.0 SDK and a third (and final) Marshmallow software preview that can be loaded on Nexus devices. “The preview images are near final but they are not intended for consumer use,” Google said in a blog post. “Remember that when Android 6.0 Marshmallow launches to the public later this fall, you’ll need to manually re-flash your device to a factory image to continue to receive consumer OTA updates for your Nexus device.”

But while Google announces its Android updates with much fanfare, it will take awhile for most Android users to start using the software. As of the first week of August, only about 18 percent of Android users were using the most current available version of the software, Lollipop. The vast majority of Android users, about 73 percent, are using KitKat and Jellybean, two older versions of the software.

By comparison, Apple’s iOS 8, which was released in September and powers iPhones and iPads, is on 85 percent of Apple’s devices.
