A good throw!

First, the less Beautiful:
Battery pack can not be exchanged,
-Nano Sim,
-wiegt subjectively quite heavy in hand
-The Camera (not yet tested under ideal conditions) makes after the first shots a good impression
Enclosures acts haptic sharp-edged, angular, hard, against the back acts (!) Like plastic, but it is not a monoblock aluminum housing?
-Not Quite as nice and flat, like other "contemporary" without battery exchange option.
-No Eyelet for wrist or neck strap.
-The Built-in speakers (not meant the ear speaker that sounds perfect, even if the sharp edge of the housing offends the ear) sounds very clean but squeaky or how precisely in the absence of resonance space and actually a little quiet

And now the good points
+ Crystal clear telephone voice quality in both directions; almost "fixed suspicious". (Back ground noise filter is not bad, but you should turn off). More than sufficient volume reserves.
+ Display excellent, no visible grid, good (switchable) solar automatic, very high final brightness possible.
+ Touchscreen responds perfectly
+ The device is "super fast", found no "lag", the 64-bit processor is obviously exploited perfectly in version 4.4.4.
+ All processing is mechanically perfectly, even if not very ergonomic because of the sharp aluminum edge. But can still be operated with one hand.
+ The "Ultra-saving circuit" is super handy when you make mainly and texting. One battery charge lasts for the pure telephone and SIM receiving operation at more than 5 minutes conversations daily, at least 8 days, in pure reception operation, a week with a few short conversations, about 10 days!
+ However, the battery endurance in wireless operation and all Internet features is estimated good two days. Every night charge certainly not necessary. (Becomes apparent that the Quad processor optimized at a relatively low clock frequency, a current savers)
+ The RF sensitivity (RF receiver) is safe in the high range, as Wi-Fi and Bluetooth, LTE not tried.
+ DLNA (with matching APP) excellent.
+ Music eg cable or BT headset is very clean, clear and set with various equalizer offers individually. No qualitative weaknesses, however, there may be small problems, only in silent shots, with the volume reserve. Here uses a 64GB SD, will probably run well even 128GB.
Prestored + Useful Utilities Apps, barely scrap more than 2-4 useless things, Good genützter large perceived memory.

So I would not exchange it for an iphone 6 this device. And I played with them and know all iPhones from the first to the last.

Have armored glass "GLASS-PROTECTOR" edition as protection, fits perfectly, does not bother, no air pockets, no slipping. And use the crystal clear (!), Not the white-milky, Moodie Transparent envelope (edges and back) as grippy non-interfering "Bumper". Makes the device grip and the phone by the rounded silicone bead on the ear pleasantly.

ATTENTION! Supplement 03.09.2015 ... and again complement error after update 15:03:15
The delivered firmware comes from December 14, and it is setting up an update of Feb. 15 (but still on 4.4.4) offered. This can be done quietly, but there is then a problem with "Google Play". A keyboard input is initially not possible because the visual keyboard and the APP screen like crazy just back and forth flashes and is hard to stop.
---- From here Correction
There is still the problem with the "Play Store" app after the update, but is easy to fix. You go to the Application Manager in settings and "delete" this APP. Nevertheless, it does not erase completely, but it will be removed only to the "factory" version of this app. If one then the APP calls, then the program will ask whether you want to save the individual keywords typed. Since then it says no, and this screen was never seen. These "old" version has no problem with the February update and everything runs smoothly. You can tell what you want, since an error is built up in the system update, the "Google Play" is changed so that it does not work in the new form. Maybe you can see the APP isolated then update again after you have turned off this memory for automatic search items in the Google Apps (in the old version) - but do not care, I leave it now so good and ists.
