I have bought this phone for 8100rs from a local showroom phone looks premium in hands by samsung because of its good looks .after using for 1 week it is ginving me hanging problem so much lag even using small applications this disappointed me alot.heating issue is common in this device camera quality is just ok in day light but detailing is so bad by the camera if becomes too blury if we zoom the picture front camera is good.its amolded display is just awsome to use in sunlight so bright as well its so dim to use in late night touch response is just awesome .soubd by speakers are also much loud and crispy.average device
