The big new feature is toggling the zoom within the Camera Controller app on the watch. The feature only works with supported Samsung smartphones ranging from Galaxy S20 to Galaxy Z Flip or later. There are two options for controlling zoom levels – via the rotating bezel or by pinch-to-zoom on the smartwatch’s touchscreen.
The other new part of the update is the Device Diagnostics tool that lets you check your watch’s battery status and touchscreen functionality via your connected phone.
