I have been using this device for the past 1 year, and I haven’t faced any single issue with this phone, not even a single time I had to get it to the service center. Very reliable and robust built quality. The Super AMOLED display is just awesome, no other brand can meet the quality of Samsung phone display.Pros-1- Super Amoled HD Display.2- Stylish Glass Body.3- Samsung UI is just awesome, provides so many extra features like secure folder and more.Cons-1- Battery life is not the best, but it works fine.2- Internal Storage is just 16GB, but you have the option of usingSD card with dual sim as well.Overall an awesome device.
