DJI Ronin-S/SC Part 8 Phone Holder
The Ronin-S/SC Phone Holder securely attaches to the camera's hot shoe mount to enable ActiveTrack 3.0, and attaches to the RSA port when using the mobile device as a camera monitor, enabling quick access to camera parameter adjustment. 
The Ronin-S/SC Phone Holder also lets you mount your mobile on a tripod or the Ronin-SC Dual Handle to control gimbal motion with Force Mobile. 
1 Camera monitor and parameter adjustment requires a Wi-Fi-enabled camera.
