I've used Xperia X and with the stock Android it performs well and the camera quality is pretty top notch. I've never seen so good pictures on phone before - however I am not very experienced in phone cameras. My plan is to backup Xperia X DRM, install SFOS with multirom and restore DRM so I have the original with the SFOS if needed but I think Jolla people are doing good job with the camera software.
