It works reliably and is easy to use, as it usually does a Windows Phone. It is a pity that Microsoft built such a weak display here. The size of 4 "is an important reason to buy a lot sure. Comparing Lumia 630 and Lumia 535, then one realizes that the writing is much more blurred, although the screen is smaller (pixel density). Extremely, it is then in the colors. Here it looks as if you have chosen a different screen color. The colors are something of pale. On the product images can be seen either in addition sprayed plastic corners, nor that the bottom control bar is no longer part of the screen and therefore also unlit. The mobile is almost twice as thick as the Lumia 535. So either wait until finally a 4 "Windows Phone 8.1 with good screen comes out, or take the Lumia 630 that is now being offered for the same price. What use a 1 GB RAM and a front camera, when the display is bad?
