The latest base OS features are on the update such as Picture in Picture viewing for video apps, autofill, smart text selection. OnePlus is also pushing Parallel Apps where different accounts logged into the same app can be accessed separately on the home screen. Other than design changes, the Launcher now features the ability to directly upload photos to the “Shot on OnePlus” community.
Oddly, you’ll be behind on security with just the September level security bulletin.
The update’s reach will be very limited for the next few days before it becomes wider.
