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

2017-12-27

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:

The YotaPhone 3 is available at least at this store for GBP548.

Dual-screen Hisense A2 smartphone is also an ereader

2017-04-10

Common smartphone screen sizes are between 5 and 6 inches, and the most common ereader screen size is six inches. Reading a book on a bright and colorful smartphone display is pretty convenient these days. The downside is that the color screen drains the battery and it is still difficult to read in sunlight. So, why not build a smartphone with two screens: a color screen for apps and a black-and-white screen for ebooks.

The Hisense A2 is the latest product that has implemented just that. The smartphone comes with a 5.5-inch color display and a 5.2 E ink display. One side of the phone is used as an ordinary smartphone and the other side an ereader. Two devices in one product.

01net had an opportunity to get their hands on a Hisense A2 prototype. Their first impression was positive, so it seems that we finally could have a proper dual-screen smartphone for ebooks by the end of 2017. The price is expected to be around 400 euros.

Similar products have been available in some markets earlier. Yotaphone has returned to the business, introducing the Yotaphone 2. Its availability, however, is unclear at the moment. Also Onyx, which has successfully introduced a number of ereaders recently, had a dual-screen smartphone earlier, but it didn’t live long.

The Hisense A2 is already available in China, running on Android software.
