What should I do?
When i try to plug my headphones to my iPhone 7 Plus I get kind of a notification that says that the accessory is not supported by the device. What should I do?
If an alert says that your accessory isn't supported or certified ..
These alerts can appear for a few reasons: Your iOS device might have a dirty or damaged charging port, your charging accessory is defective, damaged, or non Apple-certified, or your USB charger isn't designed to charge devices.
- Remove any debris from the charging port on the bottom of your device.
- Restart your iOS device.
- Try a different USB cable or charger.
- Make sure that you have the latest version of iOS.
- Contact Apple Support to set up service.
