I've spent many years in countries where I understand very little of the local language, so this has been basically my life when interacting with local apps etc. I just learn which buttons to press, largely through trial and error or a few sessions with a second phone and Google Translate in camera mode, and can get quite "fluent" with the app without ever really learning the language. This kind of "UI literacy" is not universal though; I encounter other people who are not at all capable of doing this without understanding what the text on the buttons means.
