OnePlus have just started the Open Beta 2 roll out for Android 10 OTA for the OnePlus 6 & 6T to test new features and fixes that may or may not, come to future firmware updates. You will only receive this test firmware OTA if you are already on their Open Beta releases.

Changelog



Android Security patch = October 2019

Camera version = 3.8.75

This is the 19th Open Beta release for the 6T in 320 days = 1 update, on average, every 17 days.

(N.B. Open Beta is NOT available for the T-Mobile (USA) carrier minority variant firmware)

This Open Beta 2 has yet to be tested on the converted T-Mobile (USA) carrier minority variant.

Proceed with caution!

[UPDATE]

Open Beta 2 (19) installs just fine on the converted T-Mobile (USA) models it would seem. See... https://forum.xda-developers.com/sho...postcount=4474 and https://forums.oneplus.com/threads/o...#post-21089508
