To clean a phone speaker and fix phone speakers safely, turn off the phone and remove any case. Use a soft, dry toothbrush or an anti-static brush to gently loosen dust from the speaker grille. Avoid inserting sharp objects, using liquids, or applying excessive pressure. Compressed air can help if used lightly and from a short distance. After cleaning, play audio to test the improvement. Careful cleaning often restores clearer sound without damaging the speaker components.
