I've had my Nexus since it was released in December of 2011 and have loved the camera. I'm not too informed about the new phones. Does the G2 have any shutter lag? The lack of lag is a very important feature to me. My wifes phone just died so she will inherit my Nexus. Now I just have to make a decision on which phone I get. I like the battery size of the G2. Not so sure about the button placement. Are the back buttons the volume control? Thanks!
