I seriously don’t know why the AR option is limited my phone isn’t old or anything. It’s an android OPPO f 7 great camera and specs. AR for any other game is fine. It hurts too see others phone work except mine. I love this game and I played it everyday but it hurts to see the AR button on the side of my Dino but can’t use it. The AR CORE dint work either. It’s complicated and painfull. I wish you could do something about it Ludia.
