I am a video DJ and it has been my experience that 90 percent of the time it’s a cable going bad. It is common enough that I de-embed the audio and video signal from the source and use bnc .connections on the video. If other sources are working fine. I would recommend finding a tutorial on the net on how to properly configure your phone. Are you using Bluetooth? What kind of physical connection if not. To be completely honest a phone is the worst case source for audio and video. You could pick up a cheap computer that would do 100 times better. If you are trying to use Utube depending on your equipment, if the feed detects commercial grade equipment it stops the output so you don’t use it commercially.
