4k video recording stutters
I'm on a 7 pro with the latest available software, and the factory camera app struggles with 4k videos. The videos have a few seconds of awful stutters after about 15 seconds of recording. Not just on the viewfinder, they are recorded like that. No other apps are running in the background, not that it should matter.
Good shots were ruined, and I'm not happy. Does anyone else have this problem?
