Tap Notifications
The “Notifications” setting enables an iPhone’s LED to flash when new notifications arrive. You can choose to enable it permanently or schedule it, and also take advantage of a battery saver feature which reduces app usage when the battery gets low; when that occurs, an LED indicator begins flashing to indicate when charging time has come; unfortunately this feature is unavailable on Android devices.
Mobile phone industry is an insular world. Although Danger’s Sidekick line embraced LED technology, Microsoft Windows Phones did not include LED displays and RIM’s Blackberrys no longer do so either.
