I recently bought a Nexus phone for myself. The reason I have faith in Google is why I can undoubtedly believe on Nexus and no other brand apart of it.
I got a Nexus 6(Midnight Blue, 64 GB). I got this phone from Flipkart and I got a good discount of 3000 Rs for exchanging my old phone. This has the latest android V5 lollipop OS. 2.7 GHz processor along Turbo charging feature which makes it the best phone.
Like I said I got this phone for 30000 Rs and I have now been using this since a month and very happy with the speed and looks specially.
It’s the best phone within 30K and totally worth it, go for it!
