SAMSUNG S4 is a great great at performance and camera quality it has lots of features and the are very good and easy in use.I mostly love the camera quality is very very good an no issue in performance the sound reception is not good at ll but not bad too the speakers has no quality.The design is so good to compare the other phones because is sleek and metal finishing it is perfect to get hands on it to fell it and the phone is medium heavy that is good because we not want too heavy or to light.IT has many features to descover in it and geastures features.The phone is very reliable for me.But I did not like the battery performance because it drains too early it will only handle one day without gaming.The games runs very smoothly on it because it have a Exynos 5410 octa core processor which can handle high end gaming and it has fully super amoled hd 16m colour touchscreen that we can watch movies in full HD and also it has 2 gb of ram which increases it performance and multitasking ad very easy in use.worth to buy it great value for money must buy.
