Dry your device if it has gotten wet

 Water in the speakers can cause speaker and sound issues.

• If your device gets wet, dry it immediately with a clean, soft cloth and try to remove as much water as possible. Places to pay careful attention to include:
  - Earpiece (at the top front of the device)
  - Microphones (at the top and bottom of the device)
  - Speaker (at the bottom of the device)
  - USB port
  


• Avoid exposing your device to salt water or ionized water. If your device has been submerged in salt water, rinse it with fresh water and dry it thoroughly with a clean, soft cloth.


• Avoid using heat to dry your device.

Equalize the pressure.

• Use the volume buttons to increase the volume while playing audio on your device. If the sound quality is normal, then your speakers are working properly, and the problem may be caused by an external device.

 Test the speakers

• Use the volume buttons to increase the volume while playing audio on your device. If the sound quality is normal, then your speakers are working properly, and the problem may be caused by an external device.
