Nokia have just announced that a future update coming to all WP8 Lumia devices will be receiving a new software update in the summer called Nokia Lumia Amber. Amber will debut on the Lumia 925 with Smart Camera and soon following on other WP8 devices.
According to the verge this update will come packaged with the GDR2 update which will also bring an activation to the FM transmitter:
Other features, including some camera improvements, will also be made available with the amber update. The Lumia 925 includes double-tap to wake support, and The Verge understands that the Lumia 820 and Lumia 920 will be updated to support this upcoming feature.
According to the official Windows phone Blog the update will also bring hundreds of small improvements including “datasense” being available to more carriers and phones:
The new update, which is expected to start rolling out to existing Windows Phone 8 phones later this summer, brings back support for FM radio (we heard you!) and makes the Data Sense feature of Windows Phone 8 available for more carriers to offer. The update also makes it easier to select, download, and pin tunes in Xbox Music and improves the accuracy of song info and other metadata—something I know music fans will appreciate. (FM Radio and Data Sense availability depend on your phone model and carrier.)
The update includes hundreds of other small quality improvements. One final one worth highlighting, as we announced earlier, is that the update also ensures Windows Phone continues to work with Google services by adding support for the company’s newest sync protocols—CalDAV and CardDAV.
