The update improves low-light photography on the Nokia Lumia 920 by adding more ISO settings from 800 to 3200. It also allows other Lumia models to install the Nokia Smart Camera app. This app brings some cool new features to the camera on the phone, including Best Shot, Action Shot and Motion Focus. Action Shot allows you to capture an entire action sequence on one picture with the snap of the shutter while Motion Focus adds a blur of movement to a moving object you've captured on film. Best Shot lets you look for the best picture from a series of ten shots that are taken when you snap a single picture.
Most Nokia Lumia models (not the Lumia 520 and Lumia 625) will get the new Glance Screen which offers an always-on clock. And you can awaken a sleeping phone with two quick taps. Want to silence your ringing handset? Just flip it over. Other features include HERE Maps and Data Sense. The latter is an app that keeps track on how much data you've used for the month, and also alerts you to which apps are consuming the most of your monthly data allowance. And of course, the GDR2/Amber update brings FM radio to those Nokia Lumia models that are wired for it. That would appear to be all Lumia handsets excluding the Nokia Lumia 620.
For those wondering why the Nokia Lumia 925 and Nokia Lumia 1020 aren't on the list, both models launched with the GDR2/Amber update already installed out of the box.
