I recently bought samsung galaxy core .It is very worst mobile.Because it is not good for all like private or public.It has 4GB internal memory, android version, kelliey ben version 4.0 and external memory, 8 mega fixel, big screen and 320 hard disk.
It is very slow process some time hang out the phone and some times automatically switch of the phone.Once upon it is running good but its not good thing. Camera is also running very bad .It doesn’t have much features in this mobile. I think it is worst and not useful for all.
