The latest update version for lumia, which is amber actually has been released about 2 months ago. But the update only provided for limited device based on its firmware number. If your phone hasn’t got any notice for updating, just the check availability for the update here. The firmware number can be found on the Settings > About > more information > Firmware revision number. And for checking the update just go to Settings > Phone update > check for updates.
So what’s the amber given to you? The first is enhancing on its camera capability as the video shown below. You need to download the app called Nokia smart camera first to use the features. And then the arrival of FM radio feature. The glance screen is back which display the current time. Double tap on the screen will wake up your phone while in this mode. But the double tap feature is not available for my lumia 720 and below. And there is also data sense apps which measure the using of data from both cellular and wifi.
