Okay, so I found photos of someone else on my boyfriends phone in his deleted folder, he said that he reinstalled whatsapp after getting a new phone and that when he went on it it asked to have access to his photos, now he says these photos were sent over a year ago and when he clicked on the conversation these photos which were sent over a year ago automatically saved to his phone, he doesn't have a back up though. Is this possible or is he lying?
