I think it’s fairly obvious to tell that this M9 camera update boasts
huge improvements. I wouldn’t say that this catapults the M9's camera
from terrible to outrageously awesome, but those who decided against
the M9 primarily due to the camera should consider giving it a second look.

真的好像鏡頭有沒有擦乾淨的差別唷XD不過還是希望HTC可以把相機調好，畢竟在one x比起其他同期還不錯
