Since samsung realised galaxy series it become a very popular in mobile phones brand, alpha is good looking phone and looks like the model is inspired by an Apple iphone 5 but not good in features the camera is okay but when you brought a smart phone you are not just going to use camera only there are lot of other task an smart phone can do, but all the samsung phone got one big problem which I have faced from long back that`s it freezes.
It hangs a lot and every time I need to close all the apps and sometimes reboot the phone. rather than samsung I would suggest you to go with HTC at least htc doesnt hang while using the phone.
