Over the course of a day, a lot of debris can get stuck in your iPhone's speakers, especially if you keep your iPhone in your pocket. If your iPhone speakers are full of lint, dirt, or any other gunk, they may sound muffled or not make any noise at all.
How Do I Clean Out My iPhone Speaker?
- Wipe off the speakers using a microfiber cloth.
- Clean out more compact debris using an anti-static brush or a brand new toothbrush.
