The release of the first YotaPhone certainly disappointed. It was a device I would not want next to me. Poor hardware quality, and lack of compatible software were two of the main reasons.
The second-generation YotaPhone (YotaPhone 2) but it comes with a lot of changes, improved hardware.
The design of the device has changed completely, and now it has screens (front back, yes it has a dual screen) of better quality. Its processor is much more powerful and makes better use of the screen's e-ink.
The built-in memory of the mobile is 32GB without expansion as you will see below in the detailed features, and its cameras are a bit "small" for the demanding, with an 8MP camera on the back and a 2.1MP on the front.
Το YotaPhone 2 αποτελεί τη ναυαρχίδα της Yota Devices και είναι η ρωσική απάντηση στα smartphones της China and America.
The YotaPhone combines a touch screen on the front and an ePaper (E-Ink) technology display on the back, which is "Always On." Do not be afraid of the battery, it consumes minimal energy. The E-ink screen has extremely low consumption as mentioned above, which gives the Yotaphone 2, from 2 to 5 days of autonomy.
Its battery is non-removable at 2500mAh with fast charging function, and wireless charging support. The second screen allows you to receive there the various notifications (from messenger, social media, e-mail) and read ebooks even under bright sunlight.
The Russian company Yota has the Yotaphone 2 device globally and targets the average consumer rather than those who want the latest technology, although its features as you will see below are very decent:
