Not too long ago, Nokia unveiled their latest Lumia 930 which can easily be considered as the international Nokia Lumia Icon - for the rest of the world. Similar to Nokia Lumia Icon, the handset also lacks a few features, including the glance screen as well as support for expandable storage. The glance screen is a very useful feature that not only displays the time, but also shows you missed call alerts, messages, and more. So, in short, its a very useful feature that's missing from the Lumia 930.
Ever wondered why it's not supported in the latest device? Well, the folks at WPCentral managed to sit down with Nokia, and this was one of the question that was raised. The answer as a little technical, so we're going to get right to the point. The AMOLED display technology used in the Nokia Lumia Icon and the Lumia 930 lacks the proper display memory which is needed for the glance screen to work.
The second question: why didn't Nokia used the right type of AMOLED screen with display memory? The answer was simple: it's costly. Nokia could have implemented the technology but that would have increased the price of the Lumia 930/Icon, or their profit margin might have been reduced -- either of these scenarios could have been the case.
Glance screen is a pretty handy feature, and let's just hope Nokia will be able to figure it out in the near future.
