My review of the smartphone
A good device, the battery holds day without a problem, at least for me, and I am the more gamers and music I love to listen. If you do not want to install all sorts of junk applications that devour your traffic, then you will be well.
During use of the device was not noticed any glitches. If not wisely and not to the left firmware you will too;-) Works smartly pulls everything that I need from games.
Where to buy
Find and Buy Case, headphones or adapters (eg, microUSB, miniUSB, and others) the device can be there.
