The changelog highlights the addition of notification dots (or badges), smart text selection, a new call screen, redesigned emojis, and smoother performance for apps and games. The picture-in-picture mode and other Oreo improvements should also be on board, even though we don’t see them mentioned in the changelog.
The update is available OTA, but it might need some time to reach all compatible devices. This is going to be a big patch, so make sure that your phone is sufficiently charged and connected to a Wi-Fi network before proceeding.
