Nokia X is an old model smartphone which is really does not match with current generation expectation as per price range. Now a days all smart phones comes with atleast 1 GB of ram but this phone still continues with 512 Mb of ram.
This device looks too big while holding it into hand and as well as in pocket. And I dont know how nokia got the idea to launch an operating system which is the mixing of android and windows. So I wolud suggest dont go for this device.
