A new feature called 'Pixel Glow' has been discovered in Android 17 Beta 4, hinting at potential hardware changes for the upcoming Google Pixel 11 series. This innovative notification system uses light and color to alert users when their device is face down, moving beyond traditional sound and vibration alerts. The feature, previously known as 'Light animations,' suggests that Google might introduce RGB-style LEDs on the back of the Pixel 11, allowing for a more customizable and refined notification experience. While it builds on earlier features like Flash Notifications, which illuminated the screen or camera flash for alerts, Pixel Glow aims to provide a distinct way to differentiate notifications without needing to pull the phone out of a pocket. Currently, details about customization and compatibility with third-party apps remain limited, but as Android 17 is set to launch soon, further information from Google is anticipated. This development indicates a potential shift in how notifications and smartphone design may evolve in future Pixel devices.
