Are your phones linked? It seems like they are, from how you describe things.
No they aren't linked to each other we have separate Apple IDs I just looked through his phone every now and then, lately I have been noticing him getting on Settings every day so I've looked more often, just don't know what he could do under settings every day if there's something sneaky or things you can hide under ther
maybe he is thinking why is my settings my last open app from the 'dubble click home button' and looking into it.
I would say move on from it or have a really nice talk about it, and why this is a problem for you.
There is no direct way of knowing if someone has been looking at your iPhone.
But there some indirect way of knowing. For example, he could view apps in a specific order, then if you double tap the home button to see multi tasking screen, the apps will be sorted in the order they were lasts used, if the order he left the apps is different, he might recognise it.
Same if he leaves mail or messages app on a specific message.
I'm sorry you're going through this, it sounds like you have more marital problems than technical iPhone issues.
Yes , im wrong for it , Bc he hasn't given me a reason but I'm just over thinking things wondering I guess, I never get on my settings really so I see it's an open app for him everyday just seems weird but maybe not
no there isn't. but I think there are some trust issues going on here.
I think i'm paranoid ,
No there isn't a way to see if someone has been on the phone looking through things unless things are moved or an app is not open when unlocking the phone.
can you tell if someone has looked through your phone
