The Glyph interface is designed with Glyphs lights on the back of the phone to provide users with a new way of communication and interaction. All preset Nothing ringtones and notification sound effects have a specially designed Glyph pattern. When the Glyph interface is turned on, there is an incoming call, or you receive a message notification, the Glyph interface will light up the light strip in a preset pattern. It's accompanied by sound and vibration effects.
Caution:
The Glyph interface may not be safe for people with epilepsy and others sensitive to light.
