Getting into screen performance, it reflected a fair bit of ambient light, perhaps not the best display we've seen from Huawei -- there seems to be a space between the surface of the glass and the display itself.
That's all thanks to a collection of six sensors, which keep tabs on metrics like temperature, ambient light, humidity and motion -- whether it's fingers about to touch the display or people passing in and out of the room.
