You can mount any smartphone up to 3.3' wide in its phone cradle, and its magnetic phone holder and smartphone magnetic ring allow for simple and fast mounting and unmounting. Advanced features such as hand gesture control and body shape recognition help round out its ease of use. The gimbal is controllable with the DJI Mimo app (available for iOS or Android devices), supports Bluetooth 5.0, and features a number of different modes to help simplify whatever you're trying to capture, such as Sport and Inception modes. Thanks to its magnetic smartphone mount, attaching your smartphone is easier than ever as well. Designed to improve on the already impressive Osmo Mobile 3, the DJI OM 4 smartphone gimbal packs in a stronger motor and more torque than its predecessor, with an even more compact frame that's easier to balance and fold down.
