Review on 📱 Phone Clip Holder for Xbox One S X Wireless Controller - Foldable Clamp Mount Bracket Game Accessories for iPhone 12 Pro Max, 11 Pro Max, 11, Xs, X, 8 Plus, Samsung Galaxy, LG Android Phones by Scott Spoja

Perfect fit! Not tight, not too loose, just right! The thumbscrews to tighten the phone clamp work well, I even shook my controller hard and my phone didn't budge. If you have a non-Xbox branded battery or a battery that doesn't sit flush with the back of the controller, it won't fit. Otherwise it's great!
