For a few months now that I got this phone so I can give my opinion with hindsight. I come from a Nokia Lumia 920 which already had an excellent camera, but of s4's better definition level, despite a 920 advantage in low light. This is also my first Android phone, and I must admit that this system is rather stabe despite what people say in general. I also had an iPhone 4, I tested the main smartphone systems. IOS is simple to grasp for non regulars but Android still allows more freedom level functionality. Finally I am not here to get into a debate operating system, all that to say that the delivery went well and the phone still works. cdlt
