The back of the HTC Rhyme and the HTC Sensation 4G. Both of the devices have cameras in the upper left. The Rhyme has only one LED flash, compared to the 4G's two. Speaker sound holes are just to the right of the camera lenses. For access to the SD Card slot and other internals, the bottom half of the Rhyme is removable, while the entire back of the Sensation 4G comes off.
