The Galaxy Nexus has a 5 megapixel camera in the middle of its backside, with the power button and audio ports on the right side. Though larger than the iPhone 4S, it is 5 grams lighter. Taking off the back case required using a plastic opening tool and guitar picks to remove one screw holding the speaker assembly. The camera has a serial flash memory unit to help buffer collected data, and the ear speaker pops off the motherboard easily.
