Thanks for the detailed explanation. I doubt I’ll ever need to downgrade it to Oreo so it’ll be nice to try out a cuatom rom. I have heard quite a bit of /e/ os and it might be interesting to try it for myself.
The XZ1C has a lot of features I value. The small size, a 3.5mm plug and a camera shutter button. I’ve since upgraded to the Asus Zenfone8, but I still find it to be too big unfortunately. :(
