Before you begin
Follow this guide to replace the earpiece speaker in your iPhone 16 Pro. You may need to replace your earpiece speaker if the sound coming through your iPhone's top speaker, especially during phone calls, is faint or crackling. You'll need replacement back glass adhesive to complete this repair. If your phone includes a 5G mmWave antenna (USA models only), you'll need replacement adhesive or thin, double-sided tape for it as well if your earpiece speaker doesn't include it.
