The S21 series has the ability to record 4K60FPS video from each one of its sensors. The catch is that if you start recording, you cannot switch between any lenses. You are locked to the lens you initially started recording on. My question to Samsung is if this is a hardware limitation or if it has to be added as a new feature in One UI.
UHD 60fps operates as a single camera rather than a multi-camera concept (ex: FHD30, FHD60) due to Application Processor and heat restrictions. When a lens is selected in Preview, the corresponding camera is turned on and the lens cannot be changed during recording.
