OnePlus 8T latest Oxygen OS 11 OTA update

Earlier this month, OnePlus released an exciting new firmware update for the entire OnePlus 8 series with Bitmoji for AOD support. That was under the OEMโ€™s Open Beta program for the respective devices. With this feature, you get Bitmoji integrated right into the Ambient Display on the lock screen. We were expecting Bitmoji support in the next OxygenOS 11.0.8.13 update. However, the new OxygenOS 11.0.8.13 is a mere security patch bump.
