YotaPhone 3 smartphone comes both with a color and a black-and-white screen, but why?

The YotaPhone 3 smartphone that features a 5.5-inch color screen and a 5.2-inch E ink grayscale screen is not the first dual-display phone, but it is the latest, and comes with all the features a typical smartphone user wants. There are two reasons for having a display on both sides of the phone: the E ink screen is ideal for reading, for instance, ebooks or any long texts because it doesn’t flicker, and the E ink screen is very battery friendly.

If you like to read, but don’t want to carry another device, like an e-reader with you, a dual screen phone can solve that problem. Especially people who read a lot from a screen benefit from the static E ink display that doesn’t flicker.

An E ink screen doesn’t emit light, so you need an external light source for reading. The good side is that these black-and-white screens consume very little energy, saving battery power.

The YotaPhone 3 smartphone is powered by Android 7.0 software. It comes with an additional application that is used to control what the black-and-white screen displays.

Take a look at a video below where the features and two screens of the YotaPhone 3 are shown from many angles:
