Awsome phone.I had purchased this phone in may 2016 n this hasnt given any problem yet no lag no heating issues on high end gaming.And also sound quality is very good and the credit goes to Samsung Music app.Users who say it has battery draining problem, there is no problem with me.I can play Clash of Clans( High battery draining game) for 3-4 hours continuosly n have 35 - 40% of battery still left.The keyboard is also excellent and after the marshmallow update this phone’s performance has become the best yet.Camera quality is just awsome you cant expect an Iphone camera in just 18k so I would definetly reccomend you to go for this phone.
