Nokia Lumia Amber update, what you can get from it
Nokia is starting to roll out the Lumia Amber update which gives WP8 Lumia users the Nokia Glance Screen and a range of camera improvements and features.
Nokia Glance Screen puts the clock, battery indicator, and audio status to the screen even when the phone is inactive. This should save on battery and is available in all WP8 Lumia device except for the Lumia 520 and Lumia 625 because of a smaller display memory.
The Amber update delivers improved algorithms that offer better noise reduction, color reproduction, exposure control and autofocus to every WP8 Lumia phones in the market. For the Lumia 920 this update will improve low light performance by allowing ISO control from 800 to 3200. This update comes pre-installed in the Lumia 925.
Aside from improved camera performance, the Amber update also brings the camera app found on the Lumia 925 to other Lumia phones. The app has Action Shot which combines several shots of movement into one; Motion Shot that gives the appearance of speed by blurring the background; and the usual Best Shot and Change Faces shot to combine the best faces in a group shot. All of these are done by shooting in burst mode.
The Lumia Amber update also brings Nokia Pro Camera to the Lumia 92x devices. This app allows you to edit your videos within the phone and upload it to YouTube with the Nokia Video Upload.
Another cool feature this update has is Flip to silence and Double-Tap to unlock. Flip the phone over to mute an incoming call. You can also double-tap the screen to unlock the phone without having to press and button.
The Amber rollout will happen in waves and may vary across regions. Your Lumia device will automatically check for updates periodically but you can also do a manual check by going to Settings > Phone Update.
