Android Go is Google's stripped-down OS for cheap phones
With Android phones, just as with the iPhone, the focus has long been on the latest and greatest hardware. But this ignores the fact that not everyone in the world has an ultra-powerful handset. This is something that Google recognizes, and its solution is Android Go.
Android Go is an optimized version of Android that’s designed to be used on less-powerful, cheap phones. By this, Google means phones that could have under 1GB of RAM, and the operating system -- which is essentially an offshoot of Android O -- is due to make an appearance in 2018.
