Could this mean my boyfriend is cheating?

Anonymous
So the other day, it was my boyfriends birthday. We dressed up nice and went out. He wanted me to take pictures of him by himself. He has a iPhone 12 Pro, I have the 11. I know he has a better camera than me with his phone being more updated and plus they’re his pictures so they’ll already be in his phone when he decides to post them. When he asked for me to take pictures of him I put my hand out for him to hand me his phone to do so and he got somewhat defensive and said “Umm you have your phone don’t you?” And when I told him exactly what I just said about his phone being newer, having a better camera and it making more sense to use his phone because they’re his pictures and I know he’s gonna post them, he thought about what I said, unlocked his phone and did something with it before handing it to me. Next thing I know as I’m taking pictures, the messages on his phone popped up but to where you could only see the contact name of the person messaging him, nothing more. I’m not saying I was trying to see the messages but he did scrabble around with his phone before handing it to to me. I believe that he changed his iMessage settings to that before handing me the phone and he wouldn’t do that for any reason. On top of that, I can’t forget how defensive he was over me taking the pictures with his phone instead.
