Motorola latest flagship smartphone, the Moto X comes with Active Display functionality. For your information, Active Display functionality automatically displays important notifications on the lock screen without any user input.
Active Display functionality is now available for all devices running Android 4.3 Jelly Bean. Niko001 – one of the loyal member of XDA-Developers has created and published an application called “Active Notifications”.
According to Niko001,
“It uses the new ‘Notification Listener’ service introduced in 4.3 and therefore has minimal impact on your battery. If you own an AMOLED-phone, the ‘battery saving’ feature should work automatically, since black pixels are simply not turned on. The app comes with similar features as the Moto X Active Display (such as not turning on when the device is inside your pocket, purse, or lying face down). Unfortunately, relying on the 4.3 Notification Listener also means that you need a device running Android 4.3 (which are pretty scarce at the moment)… I’ll think about creating a version for older versions of Android if there is enough interest.”
According to release notes,
“ActiveNotifications allows you to receive important notifications when your screen is off. When you miss a call or receive a new email/SMS, the display will discreetly light up to let you know, without needing to unlock the device. Most phones only have a pulsing notification LED that doesn’t actually tell you anything about the incoming notification – with ActiveNotifications, you can immediately decide if something is important enough to act.”
Right now, the application is only available for Galaxy Nexus, Nexus 4, new Nexus 7 & Galaxy S4 Google Play Edition and in case if you’re running a custom firmware you can download, install and use “ActiveNotifications,” from here.
