@pengaro yes, icons and text (the whole UI) basically are tailored to the non-XL variant screen resolution, they will look bigger on the XL since that's the scaling value it has been set to. But you can change it with the Ubuntu Touch Tweak Tool.

@michelbdec Please be more precise. Ubuntu Touch is NOT Ubuntu. Apps are using .click files. There's no Ubuntu software in Ubuntu Touch, but an open store: https://open-store.io/ in which you'll find "Dekko 2", which is currently the only email client available for Ubuntu Touch. (and works pretty well)

Btw, you can install some other Linux software using a Libertine container, but they might not work as expected, especially since they aren't design for a smartphone screen.
