For me apple is the greatest brand for making smartphones.because of the most simple and flawless user interface and for the performance the ios is the most stable operating system.t
This ios does not require very big processor and ram.the cameras are great even for the low light photography specially loves the slo mo video recorder. It is awesome for some fun.the display is just great so pleasing to the eyes unlike the samsung’s amoled displays.The battery backup is also became good.So if you want a perfect high end smartphone then you should go for the iphone.
