Why advanced camera is not the default camera app?

This is exactly the reason: few will pay to work hard a week to have a functional smartphone. Even those care about the privacy can decide to have an old Android smartphone for the banking but they expect that the main one works out-of-the-box. Ok, out-of-the-box might be a little excessive but at least the hardware works fine.

Personally, I love Xperia 10 II because is a very nice piece of hardware. I also love the SailFish OS UI (which requires some improvementt but it is very nice) and its narrative about sailors/harbour (after all, I born in Genova where marinery started for real whatever Venice people might still argouing about it, they did not sail to the new world nor with Cristoforo Colombo nor with Amerigo Vespucci).

A boat is safer in the harbour but it has not made to stay in the harbour… :blush:
