Android Oreo (codenamed Android O during development) is the eighth major release and the 15th version of the Android mobile operating system.
It was initially unveiled as an alpha quality developer preview in March 2017 and later made available to the public on August 21, 2017.
It contains several major features, including notification channels, picture-in-picture support for video, performance improvements, and battery usage optimization, and support for autofillers, Bluetooth 5, system-level integration with VoIP apps, wide color gamuts, and Wi-Fi Aware. Android Oreo also introduces two major platform features: Android Go – a software distribution of the operating system for low-end devices – and support for implementing a hardware abstraction layer.
As of January 2026, 2.56% of devices ran Android Oreo, with 1.08% on 8.0 and 1.48% on 8.1. Android Oreo was discontinued and no longer received security updates after October 2021.
