Samsung should provide back cover , screen guard etc Battery lasted for 1 1/2 day on very extensive use of various apps and many calls. Though RAM is only 1.5 GB, the phone worked super fast. It has very good camera both front and rear and excellent 3000 mah battery which gives user plentiful time in a single recharge. 4G works like a dream as its ultra-fast with almost 3 times better than 3G! Smart manager is another feature which is very good as it gives you an insight into your RAM usage and sd card details with junk removal option from your storage
