Android 8
Released in 2017, Android 8 (Oreo) introduced a host of new features designed to improve both performance and user experience. A key enhancement was Background Limits, which restricted how apps could run in the background, saving battery life and improving performance. Oreo also introduced Picture-in-Picture (PiP) mode, allowing users to continue watching videos or use apps while interacting with others, offering a more multitasking-friendly experience.
One of the most notable features of Android 8 was Notification Dots, a system that displayed small dots on app icons to alert users to new notifications, giving users a quicker way to check messages or updates. Oreo also made it easier to manage notifications by allowing users to snooze them for later. Another significant feature was Autofill, which improved app form-filling by remembering login credentials and addresses securely.
Android 8 improved battery life through optimizations in background activities, while also enhancing security with Google Play Protect, a built-in feature that scanned apps for malware. The update also brought customization options like the ability to change themes for a personalized look, and introduced project Treble, which aimed to simplify software updates for manufacturers, improving future upgrade cycles.
