 . Clean the jack port

I'd suggest you to insert your headphones and then remove them again. After that trying restarting the phone. Hope this works

If the issue still persists clean your headphone jack. Probably some dirt in there is triggering this.

Bro in the samsung members app, go to support and click diagnostics. Run a checkup on headphones
