3. Crystal-clear display
Smartphones are as much about enjoying media as they are about communicating. You watch movies, play games and view photos on your mobile screen and you want the crispest display around.
In this case that award goes to the Samsung Galaxy S4. It has the best resolution and most pixels per inch. The LG G2 and Nokia Lumia 1020 are close behind, but it's Samsung's super AMOLED display technology that sets it ahead.
While screen on the iPhone 5s and 5c can't match the size or pixel density of their competitors, it's still a solid high-resolution display and many people prefer it for its color accuracy.
4. A great camera
You don't have to be a pro photographer to see the difference between modern phone cameras and the ones on your old flip-phone. A great camera is important for more than just great photos! You can use your camera for some surprising other things, like visual search.
