These both have 6-inch screens, which is enough to make all the tiles for their Windows operating system fill up well. The 1520 has a 20 Megapixel lens and a dual LED flash, and is capable of 1080p video at 30fps. It also has that 2.2 GHz Snapdragon 800 chip from Qualcomm. The 1320 has pretty much the same features, but it has a 720p screen.
You will see the 1520 by the end of the year, but the 1320 won’t be coming until the beginning of 2014. Now, this is what I have been suspecting: smartphones are getting bigger screens. The line between smartphone and tablet is fading.
