Being new to the Pixel phone world (I've always used other phone brands, and never kept up with the Pixel models) how often does Google release a new Pixel model? Is it roughly every year? My plan is to start shopping for a new phone next year (Black Friday) to replace my 6a. I'd probably get a Pixel 10 or 11 (if the 11 is out by then, and if its supported by GrapheneOS! :) ).
