Troubleshooting serious microphone issues should start by making sure software is up to date and fully restoring your device. To do this, back up the data on your iPhone and erase all content and settings. Read our instructions on backing up your device here. Learn how to reset your content and settings here.

If this issue persists, run this series of tests to isolate the problem.

1. Plug in headphones with microphone (if available) and see whether or not you can be heard when talking into the microphone attached to your headphones. 

2. Put the phone on speaker and see whether you can be heard.

3. Open Voice Notes app and record a voice note.

If Voice Note works, but not speaker: Likely an issue with the sound cancellation. Try taking a sewing needle and pushing the pointed end through the tiny noise cancellation mic hole next to the headphone jack (but not all the way through).  Don’t worry, the hole is so small you most likely will not be able to get much of the needle head in. After that, take a vacuum cleaner to the hole and headphone jack. This should clear the passage of any obstructions.

If the speakerphone does not work, your phone will likely need repair. Contact us for more information!
