A few days ago, the dimensions of the upcoming upper-mid range Lumia 830 were leaked. If you draw a phone with those dimensions on paper and measure the diagonal distance leaving sufficient amount of distance from the sides for the bezels, you're scale will read 5.2".
I know, the leaks claim that the phone will have a 4.5" (or 4.7") screen but the leaks can also be false, right?
