How to use Pie manual rotation on a phone with physical buttons? Apparently, since Android Pie the screen can now be locked to landscape orientation (hurray! CyanogenMod (and WP8) has had this since like forever).

However, my device (Nokia 5) has physical buttons, so the method presented in the linked article does not work — and when disabling auto-rotate from the MultiCollider SuperDropdown, the screen reverts to portrait mode. How do i lock my phone into permanent horizontal orientation?
the default launcher for my phone had this as well try and install lean launcher

edit it appears that on Nokia phones with the default launcher you can't have it be in landscape 
permanently if you set auto rotate off it will just go back portrait mode but lean launcher will allow you to use your home screen in landscape if auto rotate is off
lean launcher will force apps to work in landscape mode 

turn off auto rotate hold your device in a horizontal position then click the button highlighted in the screen shot
