## Looking Deep into the Nothing Phone (3)'s Glyph Matrix Screen The Nothing Phone (3) has a new and better light-up feature. The old LED lights are now a "Glyph Matrix," a big, single-color microscreen with 489 LEDs. This makes a second screen on the phone's back. ### The Glyph Matrix on the Nothing Phone (3) Back **Main Uses of the Glyph Matrix** This Glyph Matrix helps you see info quick when the phone is faced down. Its key jobs are: * Showing messages from apps. * Putting up pictures for who is calling or texting. * Showing how far downloads or timers have gone. * Serving as a countdown before a photo is taken. * Changing volume shows by growing or dropping bars. * Plays a little show for NFC pay or sharing data. Soon, an update will make it show who is calling with just a push of a back button. ### Fun Ways to Use It and Games A round button on the back makes this screen do more things: * **Glyph Mirror:** Helps you take selfies with the back camera. * **Digital Clock:** Tells time, choosing from a 12- or 24-hour style. * **Battery Level:** Shows how much charge is left. * **Stopwatch:** Just a regular stopwatch. * **Sundial:** A fun, digital sun clock. * **Level:** Check if things are flat. * **Games:** Simple ones like "Spin the Bottle," "Rock, Paper, Scissors," and "Magic 8 Ball." ### For Developers and More Info Nothing says this is just one more fun way to use the phone. You get to change it in an app, and there's an open SDK for those who make apps. This could lead to third-party apps and new ideas for using the Glyph Matrix. Also, the Nothing Phone (3) has a tiny red light near the camera area that turns on when recording video or sound.
