Always hanging. Review on Samsung Galaxy Core 2

Hello friends, today I want to review about samsung galaxy core 2. first of all we all know about the samsung mobile phones, the more price the more stability. if the price of mobile is above 20000rs, it is nice, if its between 5,000rs.-15,000rs, samsung mobile, it is waste of money because my brother is using samsung galaxy core 2 . it is one of slowest mobiles I have used and almost all of the slowest mobiles are from samsung only, that is the greatness of samsung.,because if I installed more than 20 apps, it will be over. I cant take picture, I cant write message and even it takes so much time to open notification bar, though it has 1 gb ram it is like a 200mb ram china mobile. the cam is also not good comparing to other competitive phones in that price.,the main advantage of the mobile is that it is not a china mobile, that is the advantage because of its brand name. remaining features are very worse, I dont know why samsung is spoiling its brand name by this hanging devices, I think samsung should release a new software for those mobiles names "hangdroid software" for those,
