S4 was Samsung's flagship mobile phone last year, and s5 is this year. The difference between mobile phone and mobile phone is mainly the difference between hardware and system optimization. In hardware, s5 is more powerful than s4cpu, and the sub-pixel is slightly better, supporting 4g. Moreover, the camera pixel is higher, the system optimizes some details, and the user experience has made some progress, that's all.
IPhone5 is not good, so consider 5s, even 4s is better than 5s. As for the difference, the system is different and the hardware is different.
