The Ambient display feature can be enabled in Display Settings, once you enable it on your device, your device will light up for a few second upon receiving any new notification. The same feature that we have seen in the AOSP Lollipop ROMs.

If the firmware is available simply tap download and let it install itself else grab the 38.3.A.0.94 ftf and flash it manually. We will soon upload it here so stay tuned.
