Reports suggest that the new version will have improved notifications; however, there is no detail on how the feature will be revamped. There is speculation that the new version will adopt the notification style that was part of Andromeda leaks last year and, if this is true, synced notifications and smarter ordering may be introduced.
Android O will also reportedly bring app icon badges for active notifications, which means that app icons will keep changing based on notifications. The icons are also expected to be adaptive, which means that the calendar app icon will keep changing based on the date, which is already in iOS. The update could also bring iOS style notification badges as well.
The big feature reported is the picture-in-picture mode that essentially lets a video float in a small window while you multi-task away on other apps, similar to what was introduced on Android TV last year. The smart text selection floating toolbar with assistant integration is a lot like the copy less feature leaked recently. With this feature, users will not be required to go through the process of copying and pasting but would rather get the text as a suggestion automatically.
INCREASED BATTERY LIFE
Another vague feature is restricted background activities and this may have more to do with increasing battery life by reducing usage of power by background running apps. The report states that the MediRecorder API will also be improved, and there will be tons of enterprise stuff as well.
