Meanwhile, it has been written a lot about this here beautiful smartphone. I was lucky enough to get hold of it for 79 euros and had me busy for a few days with the device. I do not touch problem, the update had also pre-installed. Whether it is or not now, I do not know, at the moment everything is in this regard in the Lot. The quad-core processor does what he should. Surfing with WLAN is perfectly possible Mikroruckler during operation may occur, do not bother me in the least. Directions, Navi, Office programs, everything works perfectly. The use of Windows Phone 8.1 is almost foolproof. I'm almost a fan of this you OS become. However, some things that mobile on the old Windows are still possible so were no longer possible without app, or I just do not even get. Example: MP3, I map to the SD or use recordings via micro directly as a ringtone. But: battery lasts really long, the operation is liquid, LED flash is on board. I no longer need. Even if there is something to criticize, their gaze is thrown and amazed at the price. I do not know where there is competition on this model that plays in this price range. Now it needs to hold only long, it is an absolute buy recommendation.
