Nokia officially announced that Amber update will hit all Lumia devices by the end of September and will bring and will bring a number of new features, and improvements. All Lumia devices will get similar features, expect from FM Radio which will not make its way to Lumia 620 because of unsupported hardware.
Unfortunately, a recent report suggests that the Double Tap to unlock feature will not be available on a few devices including Lumia 520, Lumia 521, Lumia 620 and Lumia 720. Similarly, it’s not only Lumia 620 that will be deprived of the FM Radio, if you have a Lumia 928 and Lumia 810, you will not get the FM Radio support either. The news came from Nokia Community Forums where a Community Manager reveled all the information.
Nokia Amber Update will feature many new features including improvements to Xbox Music and Internet Explorer, Nokia Smart Camera and much more. The update will also bring improve image processing capabilities to Lumia devices such as noise reduction, colour reproduction, exposure control and autofocus.
It seems as Lumia 620 is the only device that will be deprived of many new features in the Amber update.
