Interestingly, they also seem to put upper bounds on how quickly these updates should be rolled out. Eg. functionality updates must be rolled out within 6 months after another phone from the same brand has that update. So eg. if Samsung makes Android 12 available on their flagship phone, they also need to make it available within 6 months on the other phones that were sold to up to 5 years ago.

This is such an improvement over the status quo.
