Android 8, also known as Android Oreo, is a version of the Android operating system released by Google in August 2017. It introduced several new features, including improved battery life through background limits, which restricts how apps run in the background. This helps to enhance device performance and extend battery usage. Another significant addition in Android 8 is the support for picture-in-picture mode, allowing users to watch videos while multitasking with other apps. It also brought enhanced notifications, enabling users to manage them more effectively with features like notification channels and grouped notifications for a cleaner interface.
