I purchased this product because of its design, uniqueness and also the price was very compatible against other brands.
The best feature of this phone is S pen. Hands down, the most handy. Being a student I have to edit photos of many slides from laboratory and s pen helped a lot in editing. S- pen is the only thing which is unique in samsung and thus it competes toughly with other mobile phones.
The phone hangs a lot, at least 2-3 times a day and often restart like 1-2 times in a week. Even after deleting all the material from phone it still hangs many time. The camera quality is good and satisfying.
