I installed PmOS on my old Xiaomi redmi note 9 with KDE Plasma Desktop. It works remarkably well, with the exception of sound. I am using it as a full Linux PC when I am on the go with my large power bank and a full sized folding keyboard/track pad.

For my use case it's beyond great, albeit the small screen and the aarch architecture I can develop small projects as if I was on my PC.

My current phone OP13r doesn't is supported yet by PmOS, when someone does it Im gonna try to install it on one of the slots.
