To start with, the dialer and incoming call interference will be changed with the new OxygenOS update. Users can now swipe down to answer incoming calls and swipe down to reject. This update will also bring a refreshed UI to Messages, Settings, and Contacts. Messages and Settings on the OnePlus 3T and the OnePlus 3 also get a new action bar. This action bar will be collapsible and expandable as well. OnePlus says that more customizations on the action bar will be rolled out in the future.
With this update, OnePlus has optimized the notifications system which alerts when the apps are using a lot of battery. In addition to this, the update brings Bluetooth optimizations and Night mode optimizations, along with bug fixes. Note that this update is only for users who have flashed an Open Beta who will receive it as an over-the-air (OTA) update.
