I have recently purchased samsung galaxy on max and I did not find it useful for me because I am an heavy gamer. when I played then the sound quality is good but not much as I expected.it has 4 gb ram but it does not sufficient for me because when I play it hangs badly which disturbs so much while playing. as a normal user this phone is good but according to me it is not useful for me.the style and design is good as compare to other phones but the value of phone is high . so I will suggest to my gamer friends to not to buy this phone. thank you
