Google released November 2023 update for Pixel 4a and also confirmed that their device support end dates only indicated "at least up to" dates, not actual final dates if support. That was the case for Pixel 4a that was't expected to receive updates after August 2023.
Should Pixel 4a users switch back to Google factory images for the best device security if device upgrade isn't an option? GOS support for Android 13 ended and that left Pixel 4a users vulnerable.
