S22 Ultra mic

[Dave_V6]

I have no idea if this is possible! I want to record a video with my phone but either feed audio directly into it or use an external microphone. The in built mic is pants, the sound I'm recording is played through speakers but the mixer has RCA out at line level. I guess some kind of USB C adapter, ideally with power pass through so the phone can be on charge while filming.

Is this even possible?

😊 TIA
