If you’ve managed to order a Pixel 6 or Pixel 6 Pro, you should be aware that it will take some time to get things set up and operating once the phone arrives. That’s because there’s a software update to install, according to a post on the Google support forums.

The page claims you’ll need it to use all of the functionality, but other than the November security update, it’s unclear what would be missing if you just started using the phone without it. According to Google, the build number for both phones is the identical, and Verizon customers should see SD1A.210817.036 or SD1A.210817.036.A8. If your phone is delivered early, the update may not be accessible right away.

All of the review devices, according to our staff, are running the same build when the device receives its day-one update, so any impressions you read here or elsewhere are based on the same software. This method isn’t odd for a gadget that has to be linked to the internet – it permits manufacturing to scale up while the launch software is being polished.

The day-one update will download and install in the background once you finish your device setup, and Google estimates that it will take between 25 and 50 minutes. The Pixel 6 and Pixel 6 Pro are set to arrive on October 28th, so we’ll have firsthand experiences with the upgrade (along with our reviews of both phones) soon.
