Nokia Lumia 638 is the worst phone as it is because it is a window phone and it does not have any type of front camera and it’s back camera has 5 megapixel.
I think that why these companies are allowed to launch these worst mobile phones.
Buying this is wastage of money ?? it does not have features like an android phone ?? it’s just a window phone and we can’t use these window phones on our daily life.
It does not have many of our daily uses functions.
That’s why I recommend you to do not buy this worst phone.
