While the main idea of the back screen was to make a device that can double up as a good read to a capable smartphone but what Yota did not miss out on was a chance to actually make the back screen more useful than that primary idea. The back screen also doubles up as the main screen on which you can call people, write texts and get notifications from all applications and the calls as well. They use an inbuilt feature called YotaMirror to make this possible whereby the front screens functions are mirrored onto the back screen and that can be used to perform the same actions as you would normally.
In conclusion, I will say that the only thing that will sway me to buy this device is its main design idea that is the dual-screen nature. Taking more aspects into consideration, while the sound is quite good, the camera could have been better and the lack of a storage expansion slot may push me away to look for another device. While the battery is in-built and that may or may not be a necessary con to people the fact that it has a 0-100 charge up in two hours which is quite standard and can last up to 4.5 hours under the conditions that I tested in. For a full-scale power user, it might not last that long and maybe that might be a downside since there are a few phones that can last a bit longer than that.
