Review on Adonit Photogrip (Easy-Pack) Stabilizer Hand Grip Phone Holder with Bluetooth Remote Shutter - Yellow, Compatible for iPhone 11, 11 Pro, Xs Max XR X 8+, Samsung s10/9 by Radney Taala

My wife has a similar grip for her S20 Ultra that works better than this one, but unfortunately it's out of stock right now. The difference is in the size of the handle. This one is a bit smaller and since it fits the phone snugly, the pad on your hand under your thumb tends to touch the screen and make the phone do things you'd rather not do. The grip of the other one we have sticks out further from the phone so you're not touching the screen. This one would be perfect if it were a bit wider.
