Steps to Fix iPhone Microphone Not Working

Follow these steps to troubleshoot and fix an iPhone with microphone problems:

Step 1: Check iPhone Microphone Settings

The first thing to check is your iPhone’s microphone settings. Go to:

Settings > Privacy & Security > Microphone

Make sure that the microphone is enabled and set to allow access to desired apps. If the microphone was accidentally restricted, change the settings to enable full access.

Step 2: Allow Microphone Access in Screen Time

If you use Screen Time parental controls, it’s possible the microphone was restricted here. Go to:

Settings > Screen Time > Content & Privacy Restrictions

Under Allowed Changes, check that the microphone is set to “Allow”. Enable full microphone access if needed.

Step 3: Remove Debris and Clean the Microphone

Physical blockages can prevent the microphone from working properly. Use a soft dry brush or compressed air to gently clean out the microphone opening on your iPhone. Remove any dust, lint, or other debris.

After cleaning, restart your iPhone and test the microphone again. Sometimes a simple restart can fix temporary software glitches causing microphone problems.

Step 4: Reset All Settings

If you’ve tried the above steps and the microphone still isn’t working, resetting all settings may help. Go to:

Settings > General > Transfer or Reset > Reset All Settings

This will clear any problematic settings that could be disrupting the microphone and return your iPhone to factory default settings without deleting data.

Test the microphone again after resetting the settings. Oftentimes this resolves stubborn issues that other basic troubleshooting could not.

Hardware Problems Requiring Repair

If your iPhone’s microphone still doesn’t work after trying all of the above steps, it’s likely due to a hardware problem that requires professional repair.

Some common hardware issues that can cause microphone failure include:

  • Faulty microphone component
  • Damaged microphone chipset
  • Issues with microphone wiring
  • Microphone socket damage

In these cases, you will need to contact Apple Support or visit an Apple Authorized Service Provider for diagnosis and repair options. The microphone may need to be replaced or other internal repairs are done to get it fully functional again.

While software glitches cause some microphone problems, hardware issues are often the culprit behind total microphone failure requiring professional service. Don’t attempt DIY repairs on an iPhone, as this can end up costing you more in the long run.

Preventing Future Microphone Problems

To help prevent microphone issues going forward, here are some useful tips:

  • Avoid exposing your iPhone to moisture or liquids which can damage the microphone.
  • Don’t use compressed air too forcefully when cleaning the microphone port.
  • Update to the latest iOS version for bug fixes.
  • Avoid dropping your iPhone which can loosen internal connections.
  • Use a protective case to prevent damage from bumps and shock.
  • Don’t use your iPhone microphone at extremely high volumes.

Following these microphone care tips will help extend its lifespan and reduce issues. But even with proper care, microphone problems can still occur over time. Using the troubleshooting steps outlined in this guide will get your iPhone’s microphone working again in most cases. Contact Apple support if issues persist after trying these fixes.
