What Causes iPhone 7 Microphone Problems?

Before we get into fixes, let’s look at some common reasons for the microphone not working on iPhone 7:

• Software bugs after an iOS update – New iOS versions can sometimes break things.
• Physical damage to the mic – Dropping your phone can damage the mic.
• Debris/dust blocking the mic – Pocket lint or dirt stuck in the microphone opening.
• App permission issues – An app denied access to the microphone.
• Bluetooth interference – Nearby Bluetooth devices can cause interference.
• Outdated carrier settings – Cellular carrier updates may affect connectivity.
• Low storage space – Insufficient storage prevents the mic from working properly.
• Liquid damage – Exposure to water can damage the microphone.

Luckily, even if the mic hardware is fine, most issues can be resolved with some easy troubleshooting.

How to Fix iPhone 7 Microphone Not Working

1. Check for Blocked Microphone Openings

Carefully inspect the microphone openings at the bottom, front, and back of your iPhone 7 for any debris, dust or lint blocking them. Gently clean out any visible obstructions with a toothpick or brush. Avoid compressed air.

2. Toggle Airplane Mode On/Off

Toggling airplane mode off and on again can reset connections and fix software glitches affecting the mic. Open Settings > Airplane Mode and turn it off/on.

3. Restart Your iPhone

Restarting your iPhone 7 refreshes the entire system and can resolve microphone issues caused by minor software bugs. Press and hold the side/power button to power cycle.

4. Disable Bluetooth Accessories

Interference from Bluetooth accessories like headphones can prevent the microphone from working. Disable/forget Bluetooth connections and see if the mic starts working normally.

5. Check App Permissions

If the mic isn’t working with specific apps, ensure permissions haven’t been denied. Go to Settings > Privacy > Microphone and check its enabled for problem apps.

6. Update iOS and Carrier Settings

Outdated software often causes iPhone microphone problems. Install pending iOS and carrier updates. Go to Settings > General > Software Update to get the latest iOS version.

7. Reset Network Settings

Resetting network settings fixes connectivity issues that may be stopping the mic from working properly. Go to Settings > General > Reset > Reset Network Settings.

While most issues can be resolved with basic troubleshooting, hardware damage requires professional repair. If you’ve tried everything, contact Apple Support or take it to an Apple Store. A mic replacement can fix physical damage.
