The Sony Xperia E dual comes with an HVGA LCD screen, measuring 3.5 inches in diagonal. These numbers add up to a pixel density of 165ppi, which is some way off the Retina standards, but not bad enough to be an eye-sore. You can find slightly better densities in this class, but the difference won't be too great.
As for image quality, the Xperia E dual's display offers fairly low contrast, poor viewing angles and sunlight legibility. Sadly, a mediocre screen is still one of the things you have to live with if you decide to save some money on a smartphone. Here are the results from our traditional display tests.
