Google has updated their Update your Android Version support page with dates and information on the new Google Pixel 2 lineup. When the devices were launched last month, Google made it clear that both of the second generation Pixel devices would be receiving major Android updates for three years. The update of this support page confirms it.
Both of the devices will get major Android updates, minor security patches and phone support through October 2020. That means that these devices, which launched with Android Oreo, will also see Android P, Android Q and Android R before they are out of support.
The update is a change of course from the first generation of Pixel devices and previous Nexus devices. Those devices received 2 years of major updates and 3 years of security updates. That means that the original Pixel and Pixel XL will see Android P, but that will be the end of major updates from Google.
The change in supporting the new devices for three years has been welcomed and brings Google more in line with supporting their devices with Apple.
It is important to keep in mind that the updated page only impacts Google devices. Other manufactures like Samsung, Huawei, HTC and others can have a different schedule to updates and when or if an update will be offered for their devices. That said, with Google pushing the window out to 3 years of support, it will put some pressure on manufactures to follow suit.
