Performance wise all thr chipsets are almost similar, except the 625, it is good in battery life, in gaming you’ll not notice any lag, but its not as powerful as the above. Coming to the camera, I suggest you to have a hands on, on all the phones, because I don’t think so they will able to compete with the dual cameras of the htc eye. So I used this phone I like but more faciliti are note anvaillble so I sugges add mote futures in this phone.but I like this phone and I usd this phone 2 month and I m happy.love it.
