Little holes on bottom of phone by charger port

You can use a very lightly dampened microfiber cloth (light damp, not wet) to clean them. If the doesn't work another recommendation would be to use a dry, soft bristled toothbrush (again, dry, not wet). If that doesn't work you can try to gently pry any debris out of the holes with a plastic toothpick.
