I use this mobile samsung galaxy alpha G850a since last year and I love this phone. It is a highly android phone with all facilities. It has more apps and also have at& t app. It has sharp and high pixels camera and also have the 2 gb ram and high storage space. He has also a merit of no memory catd because memory card can dead your mobile phone and harm your set. So its has own high memory and there is no need of memory card in the samsung alpha. He has the fastest android as well and run all the high low apps.
