Suppose I left my phone somewhere, and someone who has the passcode accessed the phone without telling me, and then returned it to me. Is there anyway I can know for sure that they did this? - eviltoast

Just wondering about this. I’m sure it’s possible. You can look at certain histories on apps and on browsers within the phone. But can you know whether or not someone entered the phone, looked at photos, contacts, etc. I’m sure it’s technologically possible to do this
