Better stay away from!

I have the phone now about 6 weeks.
It was the first weeks without crashes, but since about 2 weeks, it is more than 2 times a day easily and then can no longer turn on. Only after several attempts it goes again.

Wiko says "thanks to its powerful quad-core CPU (1.3GHz) running all applications, games and movies more fluid."
I can not confirm. It jerky anywhere!
Incidentally, it seems the Youtube app with Wiko devices not to function properly because bucking all videos. Whether 240p or 720p. (Apparently known problem when you google times)

Following times a list of positive and negative aspects of the device:

+ Large, sharp display with good viewing angles thanks to IPS panel.
+ Very thin
+ Price
+ Dual Sim
+ Front camera makes good pictures

- Permanent notification that no 2 SIM card is inserted.
- Camera jerky extremely
- Lousy sound speaker
- Only Android 4.2
- Permanent crashes
- Poor Performance Generally, many stuttering
- Lousy battery life
- Back very slippery
- Main camera very bad
