Step by step

1. 

   Open Glyph Interface

   Open Settings; it is the third row, under Connected devices.

   Done

2. 

   Turn on the Glyph Interface switch

   The picture shows the lights; the slider above the switch sets brightness.

   Done

3. 

   Pick what lights up

   Scroll down: Ringtones, Notifications and Essential Notifications each have their own light pattern. Features below include Flip to Glyph, Glyph Timer and Glyph Progress.

   Done

4. 

   Set a Bedtime schedule

   Under Turn off automatically, Bedtime schedule turns the lights off during set hours. Ours was set for 22:00 to 07:00, Every day, with its switch off.

   Done

If you do not see this option

• Faster on and off switch? Nothing says you can also swipe down to Quick Settings and tap Glyphs, or find the Glyph setting in the control centre. On ours the Glyphs tile (dot-grid icon) was on the first page, next to the torch. Source: How do I turn the Glyph Interface on/off? · Source: How do I turn the Glyph light on/off?

  

• Lights too bright? Nothing says to slide the bar on the Glyph Interface page to adjust brightness. On ours the slider sits just above the main switch. Source: How do I adjust the brightness of the Glyph Interface?

  

• Sensitive to flashing light? Nothing's note: the Glyph Interface may not be safe for people with epilepsy or other light-sensitive conditions. Leave it off if that applies. Source: What is the Glyph Interface?

If this does not work

• Lights don't flash for calls? Check that Bedtime schedule isn't switched on (ours was set for 22:00 to 07:00 but off). Nothing says every preset Nothing ringtone and notification sound has its own Glyph pattern, so pick a Nothing sound. Source: What is the Glyph Interface?
• Phone silent face down? That is Flip to Glyph: with the Glyph side facing up on a flat surface, the phone goes silent and alerts show as light only. See Flip to Glyph. Source: What is the Flip to Glyph feature?

About this guide

The Glyph Interface is the light panel on the back of Nothing phones. On our (4a) Pro it was on, with a Bedtime schedule from 22:00 to 07:00.

The screenshots are from our Nothing Phone (4a) Pro, the European model A069P, with Nothing OS 4.1 and Android 16 (build FroggerPro-B4.1-260424-1447-EEA), in Dark theme. The brightness and Quick Settings pictures were taken later, after the phone updated to build B4.1-260907-1153.

Good to know

Next, pick a light pattern for calls in Glyph ringtones.

For a countdown on the back of the phone, use the Glyph Timer.

In short: Settings, Glyph Interface, switch on; Bedtime schedule at the bottom.
