This was not a mistake. Google did intend to release this Android 12 update, though that caused some confusion since it coincided with the rollout of Android 13. The wording of the update notification will be changed to clear things up. Here is a statement from the company sent to 9to5Google:
On August 15, Pixel devices running an old version of Android 12 received a notification about a previously released Android 12 update with bug fixes. The messaging in the notification was confusing with the timing of Android 13, and is currently being changed for clarity.
This update is separate from the Android 13 release that started to roll out to all supported Pixel devices yesterday and will continue over the next few weeks, depending on the carrier. Users will receive a notification once the OTA becomes available for their device. We encourage users to check their Android version and update to receive the latest software when it is available for their carrier.
Google Pixel is a brand of consumer electronic devices developed by Google that runs either Chrome OS or the Android operating system. What you get is the pristine Android OS the way Google originally designed it, not masked with odd skins, proprietary overlays, or strange UIs. Pixel phones have access to beta software like new OS versions and features.
After a long wait, Google Pixel users can finally get a taste of stable Android 13 running on their devices. But not everyone is receiving the update on launch day. Various consumers from the r/GooglePixel subreddit are reporting that they got an Android 12-based mostly update as an alternative.
According to several Pixel owners online, they’re receiving a prompt to upgrade to Android 12 instead of Android 13. It is not a compact update for both but a pretty significant 2GB download. It appears to be a new update (early July, heading by the version) that involves the July protection patch and a correct for a GPS concern.
But it’s not the Android 13 update that people are expecting. So far there have been studies from Germany and the British Isles, mainly from Pixel 6 and 6 Pro house owners, but it is not restricted to just individuals two. That mentioned, it seems that the problem does not happen all too typically, however, it’s one thing to concentrate on if you happen to use a Pixel.
Some users found a solution – opt-in to the beta channel, which downloads the stable Android 13 release, then opt-out. Continue to, if you are seeing a notification for Android 12 instead of 13, it would be ideal to pause the update and wait a working day or two until finally Google resolves the challenge.
