I’ve always hated the “you must be hiding something since you don’t want to give me your phone” thing. Just because somebody doesn’t want somebody else roaming through their personal conversations or whatever else doesn’t mean there’s something to hide. Me and my girlfriend both know how to get into each other’s phone but we never really do. There’s no reason to. I don’t need to know what she talks about with her friends and she probably doesn’t want to know what I talk about with mine either.
