I use this from last month and it has a awesome performance. It has great last battery life, awesome graphics in playing game and also its a very pretty metal design device of Samsung. the curve shape has extend the impression of the rather than any one phone of Samsung. when I took this phone in hand it looks perfect grip.
in this one of the most interesting thing is its memory capacity i.e. 64 GB and it contains a lot of photos, music, games, documents e.t.c
