The last time I played with a Google Pixel phone was three years ago, with the Google Pixel 3a XL. It has since End of Line (EOL), with the last supported operating system (OS) being Android 12, which was released in 2021. The previous (and last) security patch for Pixel 3a XL was released in September 2022.
Now back to Google Pixel 7 Pro. Google Pixel 7 Pro was officially announced during Made by Google event on 7th October 2022 and was released in Singapore on 14th October 2022. There are three colors available for Pixel 7 Pro, Hazel, Snow, and Obsidian. Snow and Hazel are only available for 128GB, whereas Obsidian is available for 128GB and 256GB.
