white round objects, later a flash of bright red light

I took two videos that contained around 10 plus white round objects, in one video a red flash occurred 90 seconds into the video that was very fast and not in a straight line. The round white objects sometimes just stayed hovering and some disappeared and reappeared. I was looking for the Milky Way when I noticed all these. These were taken in a very dark sky using my Samsung Galaxy fold 3 smartphone with no flash used. Objects made no noise and had no exhaust. No lights on objects
