The new version of Android has adopted some news and features from manufacturers, which makes the system as a whole much smarter. This is the case with battery saver mode and priority notifications. Now another Moto X screen-inspired feature will be available for many other devices with the Android 5.0 distribution.
This feature was missing from the Android L preview, and has been integrated with the definitive Android 5.0 Lollipop: with the so-called Ambient Display, the smartphone screen is activated when you pick up the device or when a notification arrives. Generally speaking, this is Moto X's Active Display (or Moto Display).
According to Google, this feature will be integrated with all devices that install Android 5.0 Lollipop and have compatible hardware (which is the case with most flagships on the market). One more reason, therefore, to wait for the arrival of Android Lollipop.
