I have this Lumia 930 for around three weeks, but happiness! Its build quality, its assemblies, its absolutely wonderful screen. For its features: Windows Phone 8.1 is a marvel of clarity, everything is simple, effective, fast and user friendly! Personally FINISHED OTHER OS! Autonomy much maligned is no worse than the competition is between one and two days. I just bought to protect a leather portfolio bag STILGUT, I urge you as very well made and without reproach!
