Samsung Galaxy core 2 has very bad built quality and very slow processor. That’s two things makes the phone into a worst phone. One time the phone was drop in ground from my hand but after 1 meter of drop, the phone was stop working. Also the screen of the phone was totally break.After this, I went to service center and they charged 4000 for just set a new display. Also the processor of the phone is very slow. You can not use more than 1 apps in same time. Many hanging problem present in this phone. You can not use Internet in this phone smooth.Samsung is a reputed and brand company but they are not give good service in this phone.please samsung improve your product’s processor. This is a main things in a phone.
