So, after using the Xperia 10 II with Sailfish for over 2 weeks now there's a few things that I've noticed that are a bit of a let down.

Firstly, despite all attempts Landscape just will not work, not even in native Sailfish apps even the camera will not switch to landscape.
There's a lot of Sailfish apps that no longer work, but I guess this is because they are in desperate need of updating more than anything.
Android support is still a bit cranky as in some apps don't start until you restart Android Support in settings.
I also notice that the screen gets stuck when pulling up the apps grid as in the grid will fully open but for about 3 seconds it won't scroll.
The camera is very unstable, always giving "Camera is not responding" for a few seconds, but I'm aware of some issues with Sailfish and the Sony camera.

Are these all being addressed in future updates?
