Before you begin
Follow this guide to replace the earpiece speaker in your iPhone 16 Plus. If the sound coming through your iPhone's top speaker, especially during phone calls, is faint or crackling, your earpiece speaker may need to be replaced. You'll need replacement back glass adhesive to complete this repair. If your phone includes a 5G mmWave antenna (US models only), you'll need replacement adhesive or thin, double-sided tape for it as well.
