According to a recently updated support page, Google’s latest released smartphone Pixel 4 and Pixel 4 XL will receive security and Android updates until October 2022. This means that the Pixels 4 and 4 XL will receive Android 11, Android 12, and more Android 13, according to Google’s support page.
The Pixel 3/3 XL and Pixel 3A will also benefit from operating system updates and security until October 2021 and May 2022, respectively. With three years of updates, your Pixel 4 or Pixel 4 XL should integrate Android 11, Android 12, and Android 13, if Google publishes these updates by October 2022.
In the meantime, Monthly Android security patches will appear to eliminate the bugs. And keep you super duper secure. If you compare it to Apple, it may be a bit short, although Apple’s ongoing updates for older phones usually mean an operating system barebone shell with removed features.
