Both Nokia Lumia 630 & Nokia XL cost 10K rs/$170, but these two are from different worlds. Lumia 630 is a Windows Phone 8.1 device whereas Nokia XL is an Android 4.1 phone with Nokia X platform skin. They have lots of differences is dimensions, ports, hardware & software features though the home screen looks quite similar due to the Windows Phone like tiles on the Nokia XL.
