Phones with large displays don't sell better than phones with smaller displays. Look at the number of daily activations for Android. Subtract the S5 and Note 3 (because we kinda know those numbers from Samsung bragging). You're left with "all the rest".
Basically, there are FAR more smaller screen devices in the market than larger screen devices. The problem is that they don't have the specs of the larger screen devices. So the manufacturer already knows that small phones sell. It's just easier to market a larger phone as premium because people have a tendency to coincide large size with high-end/premium product.
That's true
