The phone looks great and feels very high quality. Compared to the Galaxy Alpha I find the size is not too large, because the border was kept small. The mobile phone does not have a notification led what does not bother me, because the LED of my s3 at night but has frequently illuminated the entire room. The battery pack initially has no weaknesses and the camera is used as Samsung, good. Overall, you get a good instrument here. However, it is not a high end smartphone. So if you and so can not do without a heart rate monitor to another smartphone to get.
