The E4's 5-inch display is sufficient to help make videos on the move as immersive as possible. It has a 960x540-pixel resolution, which results in a pixel density of 220 pixels per inch -- that's on the low side, even for a budget phone. Microsoft's Lumia 535 has the same size and resolution display, although the most recent Motorola Moto G's 5-inch display boasts a density of 294ppi. I'm hoping that Sony makes up for this meagre pixel count with a very affordable price tag.
