5 lights appearing round moving through the sky

I saw many unexplainable lights and activity over a span of a couple weeks.  This particular video was of 5 lights that appeared round moving slowly and flashing then taking off quickly. I have videos of other interesting movements and flashing from that same time period. My cell phone acted very glitchy for about a week and actually deleted some of my recordings on its own.  Also when u sent the videos to friends no images would show on their end but we’re still visible on my phone.
