Going through his phone?

I was taking a pic on my bf’s phone and I was like scrolling on his phone but not to spy on him or anything I was just on the menu I don’t even know why I didn’t even click on his texts etc but he took back his phone with force kinda upset and when I asked why he reacted that way because I always told him that I would never snoop on his phone ever, he said that his phone is his privacy

I mean I get it even if I don’t have nothing to hide from anyone I don’t like people to spy on my phone but I wouldn’t react like that ever. Does it sound normal to you? 🤷🏼‍♀️
