Since I/O 2017 not much has been said by Google about the release of Android Go or the state of development, until December 5, 2017.

Android Go has been designed from the ground up in order to accommodate the lower end devices it is tailored to power. Devices that could benefit having Android Go would be those that have 512 MB of ram to 1 GB of RAM. Android Go also takes approximately 50% less storage thanks to improvements in Android Oreo. Google also says Android Runtime (ART) compiler and enhancements in the kernel allow for apps to run 15% faster than those on stock Android Oreo.

Sagar Kamdar, Director of Product Management, Android stated in a press release,

It's common for entry level devices to have very little storage space available once you account for the size of the OS and the preinstalled apps. This can be frustrating for people who want more space for their music, apps, and photos. So, we've optimized Android Oreo (Go edition) and enhanced our preinstalled Google apps to take up 50 percent less space. The net result is that we've doubled the amount of available storage on entry-level devices.

Android Oreo is the most secure version of Android yet, so having Oreo Go gives you the same security benefits. This means Go devices will also be able to take advantage of Google Play Protect, which works continuously to make sure your data and apps are safe.

With the release of Android Go comes the re-release of 6 Google applications optimized to work for Go. These include Google Go, YouTube Go, Files Go, Google Maps Go, Gmail Go, and Google Assistant for Android (Go edition). These apps will come preinstalled on all Android Oreo Go devices.

Android Go ships with the release of Android 8.1 Oreo and any device with 1 GB of RAM or less will come with Go enabled by default. Google says the first Go branded hardware should be hitting shelves in the coming months.
