Most ":
- Excellent time interface response. Very, very fluid.
- Retina display almost (memory, 240 dpi)
- Dual SIM (mini format, I think)
- We can talk about it, Google understands!
The "minus":
- Quality of the screen: poor viewing angles, poor contrast.
- Screen Protection (plastic) seems fragile.
- The three Android buttons at the bottom of the display are not illuminated.
- Device minimum picture. It may serve you for accident reports, but do not expect to make art ..
