Reviews for the BlackBerry Evolve X
Source: The Mobile Indian

To conclude, the BlackBerry Evolve and Evolve X come loaded with a different design and the display looks promising. However, judging by the sheer specifications, the phones look overpriced. On the software front, both of them does come with privacy-driven features, but that is also present in the rest of BlackBerry devices.

It is a very small display format for smartphones. You should by no means be mis-sighted and you will generally see very little on the screen and only have a small resolution available. In return, the device should be very small and handy.
