Samsung galaxy grand quattro I have ised it for a short period of time means only for 5 months and the user experience is very bad to me because the mobiles from samsung cost high and the features are too low and the screen quality of this phone is too low and sound is also low. the phone supports only 3g network service and phone does not supports 4g network.and the cameras are not so good also.the overall look of the phone is not so good. and the android version of the phone and the battery life of the phone is also low.
