I want to buy a mobile phone that would be great for linux mobile (ubuntu touch or postmarket os), fairphone 4 would be almost ideal if it wasn't so big (i'm currently using pixel 8 + GrapheneOS). What do you recommend for my desire to use a compact mobile for linux + a solid camera? Thanks for the answers.

Hello, I am looking for the optimum phone to install Ubuntutouch on, and I particularly want optimum battery life and, of course, a great camera. Which phone would you recommend I am looking at Xiaomi Poco x3 or M3 otherwise they are big for me. I currently have a Pixel 6 and Grapheneos but I would like a Linux UT in the past I also had Xperia 10 and Sailfish os. What would you recommend for everyday use with a good camera?
