Received product on time and well packaged. Installation was a breeze, familiar android phones and the Siemens brand. The machine is well in hand, and it is relatively easy to dial calls. My contacts directory was installed in seconds, since I have all my contacts on GOOGLE, synchronization has done its job as my mobile. I installed some email boxes. Responsiveness is sufficient when I hit the keys. The only thing I have against this phone, he hangs himself too when pressing his ear to the handset. It is much more sensitive than a mobile. The battery will quickly discharge as soon as there was some installed applications. It recharges quickly. The sound, listening is perfect. I recommend
