Android Go
Variant of the Android operating system for low-end devices
Android Go, officially Android (Go edition),[2] is a stripped-down version of the Android operating system, designed for low-end and ultra-budget smartphones (but is also used by some tablets[3][4][5]). It is intended for smartphones with 2 GB of RAM[6] or less and was first made available for Android Oreo. Android Go has platform optimizations designed to reduce mobile data usage (including enabling Data Saver mode by default), and a special suite of Google Mobile Services designed to be less resource and bandwidth-intensive. The Google Play Services package was also modularized to reduce its memory footprint.[7] The Google Play Store will highlight lighter apps suited for these devices.[8][9]
The operating system's interface differs from that of stock Android, with the quick-settings panel giving greater prominence to information regarding the battery, mobile-data limit, and available storage; the recent apps menu using a modified layout and being limited to four apps (in order to reduce RAM consumption), and an application programming interface (API) for allowing mobile carriers to implement data-tracking and top-ups within the Android settings menu.[7] Some system services are disabled such as Notification access, Split-screen, and Picture-in-picture mode to improve performance.
Most devices running Android Go use Google's "stock" Android GUI, although there are several manufacturers that still use customized GUI.
