The idea of having a second e-ink display on the back of a phone to keep books, boarding cards or shopping lists visible at all times without wasting a lot of energy is not new. The Yotaphone and its successor, the Yotaphone 2 out of Russia were the first to do just that, however the concept did not prove to be successful amongst customers mainly because of the high costs involved. It also never reached the US officially.
Now, Chinese tech company Hisense is apparently trying to give the concept a third chance. A new phone named A2 according to TENAA leaks, integrates a 5.5 inch AMOLED display with Full-HD resolution and a second 5.17 inch e-ink display on the back of the phone featuring 960 x 540 pixels, similar to the Yotaphone 2. The processor will be a quad-core running at 1.4 Ghz, possibly a Snapdragon 430. 4 GB of RAM and 64 GB of expandable onboard storage will be available.
The Hisense A2 is supposed to feature a 16 megapixel camera on the back and a 5 megapixel lens on the front, however, it might be possible to use the rear camera for selfies thanks to the second display on the back. Both earpiece and sensors are available on both sides of the phone. The fingerprint sensor is integrated in the home button on the side of the phone, similar to some Sony Xperia phones. The 8.4 mm thick metal case will house a 3,000 mAh battery. At the moment it is unclear if the Hisense A2 will be available outside of China. Pricing and availability is also unclear at this point in time.
