Thanks @TheKit! Latest build SailfishOS 2.1.0.11 seems to work good on stock slot. I'm just struggling to get landscape rotation working in home screen and not supported apps by stock. Is there any updated guide? I tried to install a patch from Warehouse but it gives me error.

EDIT: I found this guide: Howto auto-rotate homescreen and all other apps

However, I don't know how to install Zypper. Is there any other way or good guide for Zypper?
