The advanced video camera technology built in to let your creative side run wild. When you're out on an adventure, you are able to record video with action-cam clarity thanks to Super steady. It acts as a camera stabilizer when you're shooting video, letting you keep up with the action in the moment without needing to set up a tripod or pack an extra action camera. With Super steady serving as a video stabilizer, you can record the moment with less blur and shake, even if you and the subject are both on the move.
To utilize Super steady, toggle the Super steady icon on the viewfinder. You can find it in Quick Settings (Please watch the attached video for more details).

The way in which this feature works is it uses the Ultra-wide camera (123°) with a larger field of view and crops the video using the wider view, stablizing it using software. The only limitations are slightly off colours/ lack of vividness compared to the main camera and video resolution limit of FHD (1920 x 1080) 30fps.
