What to do if your microphone or speaker is not working properly?

• Remove anything plugged into the headphone jack, including selfie sticks, charms, etc.
• Remove any third-party cases, protective films, skins, adhesives, or any other accessory that usually comes in contact with your phone.
• Disable Bluetooth by swiping down from the top of the screen using two fingers to open the Quick settings panel. Tap the Bluetooth icon to turn off Bluetooth.

Press and hold the Power button for a few seconds until the Power menu appears. Tap Power off, and then tap Power off again to confirm.

On phones without a dedicated Power button, swipe down with two fingers from the top of the screen to open the Quick settings panel. Tap the Power icon at the top of the screen, and then tap Power off. Tap Power off again to confirm.

Once the phone shuts down, wait 30 seconds, and then press the Power button to power on your phone.

Audio problems can occur if there is water in the speaker. If your device has gotten wet, dry it off right away and try to remove as much water as possible. Be sure to pat the earpiece (at the top front of the phone), the primary microphone (at the bottom of the phone), external speaker (also at the bottom of the phone), and the USB port with a clean, soft cloth.

Do not expose the phone to salt water or ionized water. If your phone is exposed to salt water, wash the phone with fresh water, and then dry it thoroughly with a clean, soft cloth. Otherwise, when it dries, salt may accumulate and block the primary microphone, earpiece, or external speaker.

The speakers may sound quiet, crackly, or distorted if the phone has recently undergone a large change in ambient air pressure. This is a due to the water resistant features of many Galaxy phones.

In most cases, the pressure will equalize over time, however you can speed the process along by temporarily opening the SIM tray.

Insert your SIM tool into hole one the SIM tray and carefully slide the tray out about halfway. It only takes a moment for pressure to equalize, so you can immediately close the tray.

Use the Volume buttons while playing music to ensure the sound is not muted. If the sound quality is fine, then your speaker is working normally.
