update arrives in the middle of the month now for the Pixel 6 and Pixel 6 Pro. Currently the only known change is digit one in the build number. Google has moved from SD1A.210817.036 to SD1A.210817.037 and both versions are in the November patch.
Two users in the comments section of the Droid-Life story reported that the update comes in at 14.56MB and users on Verizon, Fi, T-Mobile, and unlocked devices are seeing an OTA notification. Others say the update takes over an hour to fully install.
At least two commenters claimed that the fingerprint scanner runs faster. Another user claims that the camera now rotates UI elements with the phone’s orientation, so there might be some other updates to the camera as well. Google has not released any official change log for this OTA update.
