I am new in smartphone but he seems quite well for a not unreasonable price. The screen is sharp, you can put a micro SD card of 32GB. It is fast. It's a little complicated with all applications that are at the beginning when smartphone knows nothing about but we made it fast. In addition, terrestrial radio can receive the wire of the headset acting as an antenna. I'm at Free 4G Mobile and it works. One can listen to music and radio, I downloaded the cycle map of my city. You can also phone and texting course, we end up forgetting that this is a phone ... EDIT (22 July 2014) to use, it reveals another of its qualities, it recharges quickly; more icing on the cake, I received today the update of Android 4.4.2 Kitkat. So it is now completely up to date, allowing notably more fully encrypt the phone and the micro SD card. I really do not regret this purchase two months later. I see also that the price has dropped.
