Many users complained regarding the camera performance, especially with the third party application. Thus, OnePlus improved the stability. This update also improves the front camera performance (selfies) in low light. Above all, it also brings assistive lighting for face unlock which will brighten up the display in low light to unlock the phone. Last but not least, the update also brings improvements for WiFi display.
The update is being currently rolled out and only handful of users have received it yet. However, it will be hitting every OnePlus 5T soon.
