Probably the best phone under 15k.
Specifications
Display: 5.5 full HD display with 401ppi and gorilla glass 3 protection.Great viewing angles both indoors and outdoors.
Camera: 16 mp rear with dual led flash and laser auto focus with makes it really best camera in this price range. 5 mp front selfie camera is also very good. Picture quality of both rear and front cameras is really good in both indoors and outdoors and also in low light conditions.( camera is the main highlighting feature of this phone)
Operating system: The phone is running on android 6.0.1 marshmallow.
Colors: Black and White.
Memory: Two variants 16gb, 2gb RAM or 32gb, 3gb RAM
Sensors: Fingerprint( Finger print sensor is really fast) gyroscope, proximity
Battery: 3000mAh and supports turbo charger within the box which is really nice.
NOTE: I suggest 32gb and 3gb RAM variant because costs 1500rs extra for it.
