With Android Pie now available (on a handful of devices, at least), Google’s prepping the launch of its low-powered counterpart. Android 9 Pie (Go edition) — the successor to the more pithily named Android Go — will be hitting arriving on devices this fall.

Like Android Oreo (Go Edition), the latest OS is a stripped down version of its latest full operating system, designed to run on devices with 1GB of RAM. The more modest hardware requirements make it a compelling match for low-cost devices and thus a solid option for developing markets.
