Nokia Amber is software for improving the performance of the Nokia smartphone running on the windows phone 8 OS. The release of the amber update was planned for some time later however the NokiaLumia 920 and 820 users and avail this software now.
The other lumia handsets like 720, 620 and 520 can also get their handset on this software soon within this month. If you are updating the software now to your handset make sure you have backed up all your apps, data and other information. I am saying this because flashing the image may wipe off all the data.
The amber update would contain all the WP8 GDR2 updates. The update is going to give the users an enhanced feature. The amber update would contain features like:
- Smart camera application: some new features would be added including the action camera
- Glance screen: for comfortable viewing of notification
- Data sense application
- Update the Radio
- New silent mode: just flip through to enable the silent mode
- Here app: there would be some updates in the Nokia HERE app. The update would involve here maps V3.4, drive+ v2.2 and transit 3.5
You can update your phone right away. However note that the official Microsoft update has not yet arrived. It would be safer to update the amber once it has arrived officially. Anyways if you want to download it now you can do that but make sure you have backed up the entire phone.
