Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
Mainly in terms of firmware for actual phones, taking photos is basically impossible as the photos either look horrible or don’t work at all. Frequent sound issues, lower battery life, unreliable mobile network connection and lack of inbuilt esim support. OSes based on halium have better experience though they do still lack the app support.
