YotaPhone The Android system is running, but we noticed that the machine does not have the familiar home page, return and other buttons, but uses gesture operations in operation: scanning the full screen from right to left is equivalent to the "Home" button, if you stop in the center, it is equivalent to the return button, and long press will enter the Android multi task menu, and so on. The material selection and technology of YotaPhone are also worth mentioning. Its Sim card slot and key switch are designed in an integrated way. In addition, it is the first mobile phone to use the third generation of gorilla glass launched by Corning.

The 4.3-inch E-ink screen on the back of YotaPhone is undoubtedly the biggest highlight of this phone. The display on the back is always on, which can be a highlight. Because the E-ink screen has low power consumption, it can continuously display e-books, screenshots, weather information, reminders and social network information for users. Yota also showed several applications on the E-link screen, such as RSS, Twitter, and so on. Click to send the content to the E-link screen for viewing and refreshing. Even an ordinary app can send content to the back by sliding two fingers side by side. At the same time, the company said that the SDK development tool will be opened soon so that developers can develop and integrate applications.
