I am using samsung galaxy note 3 approximately from last 2 years. I had not faced any type of problem and note 3 have many different functions compare to other high range smart phone. Its look is also good. Camera quality and display is awesome.
If any one want to purchase it u can purchase it. Battery is also good. In moderate use its battery life will last 14-15 hour. In normal use more than one and a half day.
