For a manufacturer that had at one time smartphones with the largest displays around (remember those massive Communicators, anyone?), Nokia has been decidedly stubborn about not getting into the phablet race. However, the company has been gently increasing the size of its smartphone displays. The Lumia 925 and 920 both sported 4.5-inch displays, and now comes the Lumia 625, which sports a 4.7-inch display, the biggest on a Lumia device yet (we are hearing rumours of a Nokia phablet as we write this).
