I was using the Note 9 to record some fireworks, but during recording, there were moments where the screen would freeze up for 2-3 seconds throughout the entire video. I had assumed the phone was just busy working on whatever it needed to do in order to process the video, but during replay, the moments where the screen froze was also recorded on the device. I did not experience the same issue on my Note 8 on a separate occasion, also recording fireworks. Is this a known issue?
