Hey friends I have used samsung mobiles two times in life. The samsung galaxy s duos 2 was my 2nd mobile. Samsung mobiles hangs too much its a universal truth. And this mobile is one of them. The mobile is not worth of money. But camera and flash is too good. UI is also awesome. Works very smoothly with 2 or 3 apps, if u download 2 or more messengers in it, it hangs badly. The best thing of samsung mobiles is their touch response.
The only thing I like in samsung is their touch response. This piece also have a really good touch response. I buy this because there were no too much options in market that time. They should fix the problem. Design is simple but good enough. Voice clarity is also good. In present time buying a samsung mobile is totally wastage of money cause of hanging problem. Now a days there are many good brands for customers to choose.
