Though we all know NOKIA is a big brand as per indian market is concerned. I bought this phone around 8-9 months back.
Though its not a complete android phone but has all features of android as it contains 1 mobile market instead of play store. but there is a problem few applications which does not work in this phone like snapchat, hill climb racing.
The problem of this phone contains- low quality camera, it says 5 mp.but does not even match 5mp quality at all and other problem is back panel is not available in market not even on nokia store. also the fact nokia x2 glass is not gorilla glass, catches scratches after a while.
YOU can say the phone is not bad, but not a good phone if you are looking for good camera quality or you are looking for complete android coz you will get to face few difficulties in application every now and then.
