The Xun Chi 138 may be the world's smallest mobile phone at 67mm long. It supposedly has a 1.3 "mega plixs" camera capable of shooting both stills and video. 

As major smartphone manufacturers trend toward the 5-inch format seen in the new Samsung Galaxy S4,  Sony Xperia Z and more, some other mobile phone makers are thinking on a smaller scale. 

Technology website Tech Info 2 recently shared a list of some of the world's tiniest cell phones for children, but, really, anyone looking to downsize their mobile could try one of these itty-bitty devices. We can only vouch for the cuteness of these phones -- the camera specs of most match their minature scale, but as we know, the photographer is far more important than the number of megapixels.

The Modu T may be the best of the small smartphone stature bunch in terms of capture capablities with a 5-megapixel camera and LED flash. The device measures 75 x 46.5 x 11mm.

The Cellwatch M500 may satisfy your James Bond fantasies by squeezing a plethora of tech into the size of a standard wrist watch. Its 2-megapixel camera would let you shoot stills and video on the sly.

Billed as the world’s smallest slider phone, the Samsung SGH-E888 offers a 1.3-megapixel camera that can rotate 180 degrees and includes a flash.
