There are quite a few large sized smartphone devices doing the rounds in the market right now. Consumer attraction for the large screen on their smartphone devices has been very positive and makers of the devices are keeping that part in mind when designing future devices. As of now the largest of the lot in smartphones is the Sony Xperia Z Ultra which comes with 6.4 inch display. The closest in screen size is the Samsung Galaxy Mega 6.3. The Sony model beats the Samsung one by a mere 0.1 inch.
The Sony Xperia Z Ultra has its share of contrasting user opinion on account of its display which is quite large by smartphone standards. Some say it is too large to be mobile in the real sense and term it closer to a tablet. There is quite some comment of this sort going around and these comments should hold themselves in check for a while as there is supposedly going to be a further addition of another device of similar size so far as the smartphone segment goes.
Peter Torr has placed a note on the Windows Phone Developer Blog about a day coming when there would be a Windows Phone which is 7 inch by size. So there is the possibility of Microsoft coming up with a Smartphone that is 7 inch in size, which if true will comfortably beat the Sony Xperia Z Ultra and its 6.4 inch display. Curently the biggest device running Windows Phone 8 is the NOkia Lumia 1520 that comes with a 6 inch display.
Torr was writing in the blog on the issue of Microsoft coming up with the GDR3 update. The specific aspect about the update is that it allows the device to sense the size of the display when it renders the contents. What this means is that the device need not just display some additional items to fill up the screen, instead the content would be adjusted by dimension to fit the screen optimally. An elastic property to the content for display on the screen would be added. That leads to the assumption that larger screen smartphone devices could have a possibility of being made in a big way in the near future.
