Coolpad’s note 3 was the cheapest phone to have a fingerprint scanner and 3gb of ram at just 8, 999/-.
This phone has mediatek MT6753 octa processor clocked at 1.3ghz coupled with 3gb of ram and 16 gb of internal storage. Out of these you get around 10gb of internal memory and 2.2gb of ram. All these combined gives you an awesome experience even while playnig high end games and gives a score of around 36000 on antutu benchmarks.
The biggest pros of this phone the fingerprint scanner is just awesome. It unlocks the phone in just a mere tap on it. And you can also lock applications by a pre-loaded app called FP scanner.
This phone runs on android 5.1 and is availabe on amazon.in exclusively and is in two colors white and black.
The only disadvantage what I think is its display which is a hd display and not a full hd like k3 note or any other phone in its price segment.
