Linux on all my computers and GrapheneOS on my Google Pixel 6a with 99.8% FOSS applications. Maybe 96% FOSS softwares on my stationary computer and 100% on my laptops.
With GrapheneOS do you still get the same quality photos as you would with the stock OS?
I use Open Camera and the quality is very good. Especially the night mode! What you see with your eyes in a dark room with the TV on, that’s what you will see in the photo. Not the same quality on the TV in the photo, of course, but very close.
