Im searching for a FOSS office suite for android that is not cloud based and that lets me both view, create, and edit documents so far the only thing that i found that meets all those requirements is collabora, BUT IS TRASH!, i literally cannot even scroll down without it glitching out and sending me to a whole different part of the document!
i’ve kinda looked into it and my solution was running full libreoffice inside proot inside termux using termux-x11. kinda glitchy but it is surprisingly usable on a tablet+keyboard.
