In photos you barely see the difference between the two models; in real life the Huawei Y7 turns out to be a fraction larger. The budget phones both have a touch screen, of 5.7 and 6 inches respectively, with an aspect ratio of 18:9. This increasingly popular aspect ratio offers somewhat more practically useful area than a standard 16:9 screen. The longer display lends itself exceptionally well for example to the so-called split screen mode, in which you can use two apps side by side.
On the back we do discover one difference: the fingerprint scanner, which is only on the Huawei Y7.
