Android Android Phones Phone Headphone Jack Not Working: How to Fix It Yourself

If your headphones do not work when plugged in, or the audio cuts in and out, the headphone jack is almost always clogged with lint. This is a free 2-minute fix. Try that before assuming the jack is broken.

Step-by-Step Repair

  1. 1

    Test with different headphones

    Before cleaning anything, try a different pair of wired headphones. If the second pair works, your original headphones have a bad plug or cable. If neither pair works, the problem is with the phone's headphone jack.

  2. 2

    Clean lint from the headphone jack

    Shine a flashlight into the headphone jack. You will likely see packed lint at the bottom — this prevents the plug from making contact. Use a wooden or plastic toothpick to gently scrape the bottom and sides of the jack. Pull out any lint. Use compressed air for a final clean.

  3. 3

    Check audio routing settings

    Make sure your phone is not routing audio to Bluetooth. Turn off Bluetooth and try the headphones again. Also check if your phone has an audio output setting — some phones let you choose between headphones and speaker, and it may be set wrong.

  4. 4

    Restart your phone

    Restart the phone with the headphones plugged in. Some audio routing bugs only clear after a restart with headphones connected. After the restart, play music and check if audio comes through the headphones.

  5. 5

    Check for water or corrosion

    If the phone was exposed to water or sweat, the headphone jack contacts may be corroded. Plug and unplug the headphones 10-15 times — the friction can clean light corrosion. If that helps temporarily but the problem returns, the jack may need replacement.

If That Didn't Work

  • A headphone plug that is slightly bent will not make proper contact.
  • Some phone cases are too thick and prevent the headphone plug from inserting fully.
  • A TRRS (4-ring) headphone plug may not work in a TRS (3-ring) jack on some devices.
  • A USB-C to 3.5mm adapter may be needed if your phone does not have a headphone jack.

When to Call a Professional

If cleaning did not fix the jack and you have tried multiple working headphones, the jack itself may be physically damaged. A repair shop can replace the headphone jack module. As a cheaper alternative, consider using Bluetooth headphones or a USB-C audio adapter.
