Certainly one of the best android, but not "iPhone killer"

Certainly one of the finest products on the market for Android.
Display size is exactly the right balance between expediency and handiness.
Housing processing, style and feel are really well done and a valuable aspect.
Only the lateral recess for the magnetic charging cable or the charger is ugly.
A suspicious impression makes the cover of the USB connector. Whether the long time survived because it opens and decremented with each loading process, seems uncertain to me.

The device itself is determined outstanding, compared to the plastic competition.
But to the harmonious overall quality of an iPhone it does not come close.
Even the battery life remains far below that of an iPhone.

The display is designed well, but a "wow" over the other, current device does not exist.
In direct sunlight difficult to read, as with so many devices.

The 20 Mpix camera now delivers no images that are noticeably better than those of other mobile phones.
This suggests Sony in advertising too much.

Although Android updates are supplied by Sony, but it is possible for several weeks after release by Google.

+ Housing, feel, style
- Battery life, connection covers

What one of the relatively high price still feel good: the water- and dust-tight.
I think it's worth it if you want to have a device for longer again. Otherwise, if you're oftmaliger devices changer eh, you can access even more favorable to competition.
