No sound from the bottom speaker on your iPhone 16 Plus? That is your loudspeaker, and it is crucial for music, ringtones, and speakerphone calls on the larger Plus model. At My Cell Repair in Santa Rosa, California, we fix iPhone 16 Plus loudspeakers for $120. Sometimes the issue is just debris packed into the speaker grille, which we can clean. But if the speaker itself is blown or has failed, we will replace the entire loudspeaker module. You will walk out with full, clear sound again. Most loudspeaker repairs are finished the same day.
