A smartphone with a rotating camera? Now where have we heard of this particular idea from before? I suppose you would have to roll back a fair number of years to the days when Nokia still commanded quite a large amount of the global mobile phone share, with the Nokia N90 sporting a unique form factor which is able to let you adjust where the camera points. Having said that, the Oppo N3 has just been leaked, and it sports a rotating camera as well, allowing you to employ the primary camera on the Oppo N3 to capture selfies in high quality.
