Compared to my Nexus 4 and the Lumia 925 (not to mention the price):
+ At least same performance
+ Screen in similar quality (but not compared to the display of Nokia)
+ Significantly lighter (110 g are an announcement!)
+ Significantly longer duration (on average use 2 days!)
+ Works with Sony SmartWatch 2, Withings Pulse, Sony QX10 Smart shot lens and Bluetooth 4.0 HRM smart belt without problems (as opposed to the disconnections when Nexus 4)
+ Miracast with CloudnetGo stick without problems (even films can be quite good view, in contrast, no stable connection to the Nexus 4 and significantly worse transfer)
+ 64GB Micro SD in the device to work (although officially only 32 GB are supported)
+ Very good phone voice quality
+ Shooting outdoors in good exposure succeed better (colors) and sharper compared to the Nexus 4 (no comparison but the Lumia 925)
+ GPS fix is fast (less than 3 seconds) and the accuracy is sufficient for navigation and sport
+ USB OTG without problems
+ And balanced sounding speakers (but only mono)
+ Finally a visible notification LED
+ Pinpoint and sensitive touch screen
+ Subjective sound quality is the Nexus 4 par
+ Compelling HD video recording, even at rather poor exposure
+ Preinstalled Touch Pal Keyboard
For these reasons, I use now the Wiko as main unit. But there are also disadvantages.
So the very bright and viewing angle stable screen is very susceptible to dirt. Fingerprints are almost always visible. Probably lacks an appropriate grease-proof coating of the display. Furthermore, the device has a tangible edge around the screen and does not flatter your fingers as the sloping outward displays of Nokia 925 and Nexus. 4
The dual SIM capability has really excited me. You have to just be aware that only can run a SIM card in the 3G network in each case. The second card supports a maximum then EDGE data connection. But you can adjust on the SIM management software for the respective card. Different ringtones can be set per SIM.
The non-existent NFC chip and LTE support nonexistent I have not really been missing. While the camera is really respectable shots in daylight, you have to keep very quiet in the dim light the phone to still make useful images. The LED flash is really only for very close subjects.
A useful special feature is the integrated Smart Gesture. This allows different control options by proximity sensor and gestures (for example, mute the ringer or speaker for incoming calls by turning the phone from portrait to landscape mode, automatic answer by approaching the phone at the face ).
The 1 GB internal memory for apps scarcely measured, however quickly filled even with a normal user. This also applies when you outsource movable apps to the Mirco-SD.
One can with some craft effort to change the partitioning and increase the phone memory significantly. But this tinkering is some scare (see various Android forums).
The extent to which software updates come from the manufacturer, remains to be seen. So far, however, the equipment WIKO has relatively quickly served with reasonably current Android versions. Whether that remains at the large number of new devices, the Wiko currently brings on the market, however, is questionable.
The enthusiasm of the forum users on the device reminds me of the enthusiasm that was associated with the sale of the ZTE Blade. This suggests to me that even on the manufacturer support addition, can be expected with an early CUSTOM-ROM support.
As an accessory, the Wiko Darkmoon flip cover compulsory, as this protective sheath perfectly complements the ease and feel of the device (LED notification remains visible in bag closed).
Conclusion:
Very effective and lightweight smartphone with good performance and impressive maturity. Software additions like Smart Gesture and TouchPal keyboard and extensibility through MircoSD complete the picture. Refrain must, however, on NFC and LTE. A slight limitation of usability is given only by the relatively small internal memory. Users can store many eating Apps should therefore take into account a Neupartition of memory and the craft work involved.
