95% certainty it's just lint. Take a toothpick and poke around in there, you'll be surprised how much fluff it collects from sitting in a pocket for a while. Don't worry, nothing in there can break from a wooden toothpick or similar instrument - use some force and get into the back corners properly. Lightning ports are notorious for this, I clean mine every 1-2 months and it's noticeable every time.
I did that, didn’t fix the issue.
