The iPhone X will hit the shelves on Friday, November 3 and we’re still hearing about the new features which it will have in store for users. With that said, there is a small addition made in the iPhone X which will probably remain exclusive to the device. That’s right, the iPhone X features a new ringtone called “Reflection” which will be set as a default ringtone on the device. Up until now, the ‘Opening’ ringtone was available as the default ringtone since the release of iOS 7. So let’s dive in to see some more details on the matter.

As we have mentioned earlier, the new ‘Reflection’ ringtone will be exclusive to the iPhone X and is the default for the iPhone. However, if you’re a fan of the ‘Opening’ tone, it is still present in the list of sounds that you can choose to set as your ringtone. So you can simply change the default ‘Reflection’ ringtone to ‘Opening’ from the sound settings.
