iPhone 16 Pro Max speaker not working: fix no sound

These are the checks Apple gives when a speaker plays nothing or sounds distorted.

1. Check Silent mode. The iPhone 16 Pro Max has an Action button instead of a Ring/Silent switch, so open Control Center or press the Action button if it is set to Silent.
2. Open Settings > Focus > Do Not Disturb and make sure it is off.
3. Remove any case, screen protector or film.
4. Look at the speaker opening at the bottom and the receiver at the top for dirt or blockage.
5. Clean the openings with a small, soft-bristled brush and keep them dry.
6. Open Settings > Sounds & Haptics and drag the Ringtone and Alerts slider back and forth a few times.
7. If you hear sound now, make a call with speakerphone on to test call audio.

If the slider plays nothing, or its speaker button is dimmed, the speaker likely needs service.

iPhone 16 Pro Max screen issues: fix an unresponsive or jumpy touch screen

These are Apple's steps for an unresponsive iPhone touch screen that is too sensitive or responds only some of the time.

2. Clean the screen so it is free of debris and water.
3. Disconnect any USB-C accessory. If the screen works without it, try a different outlet, cable or charger.
4. Remove the case and any screen protector.
5. Install the latest iOS from Settings > General > Software Update.

3. Press and hold the side button until you see the Apple logo. This can take longer than 10 seconds.

When iPhone 16 Pro Max needs Apple service

Book service with Apple if the speaker stays silent on the Ringtone and Alerts test, or the screen still misbehaves after updating, cleaning, removing accessories and force restarting.
