Most smartphones now come with an application that connects to your smartphone and the gimbal. The app opens up many additional features, including remote control via the gimbal. You can use buttons, wheels, triggers, joysticks, and triggers to zoom in, focus, pull focus and pan the camera. All gimbals are different in terms of their features. It's worth looking into what features are available, and how the app integrates with your phone's operating system. Many apps that are designed for use with the gimbal offer control over the camera of your phone, giving you access varying degrees of manual control. You can set ISO, framerate, and video resolution using the app.
