Hello , so am changing my phone(Samsung) to iphone , thing is I've always been an android user so I don't know much about iphones, so my question is about this Apple Id thing, like am getting the iphone second hand , I mean it was only been used like a month by a relative Ena when I sign out will I have my absolute privacy? Like the former owner couldn't access/see any of my data on my iphone? I heard the owner can always see ur photos and staff coz it was first Registered by their name , I dk if matters on the privacy policy but am getting iphone 12.
