Prepositions are always a fun part to learn of a language. Right now, I'm running into the difficulty of trying to describe "On My Phone". I've heard people say "手机上“ but, after Baiduing I also know that you can say stuff like "手机里的照片“。 Could anyone give their opinion on which is more commonly used and/or any differences in usage?
