Ahoj Eleno,
I’m trying to figure this out too! I’m also running out of space on my phone. I read that some file manager apps can show hidden files. Is it safe to use those? I’m worried about accidentally deleting something important and messing up my phone.
Also, is it legal to look at these hidden files? I don’t want to get in trouble. I’ve heard connecting the phone to a computer might work, but I’m not sure how to do that. Does anyone know if that’s easier or safer?
