We do regret for the inconvenience caused while recording videos is 4K mode. Let me recommend some steps to further isolate and determine the issue faced by you in your device.
- Check the video size (Camera Capacity) in camera setting (It should be Max according to Camera Capacity). - Reset the Camera (From the Camera Setting). - Open settings>>Device maintenance>>Optimize now. - Software update via FOTA, Kies or SMART Tool.
