Oppo N1 puts a 13MP camera on a hinge, comes with CyanogenMod extras
Oppo's been prepping its photography-centric N1  for quite some time, but at last, the teasing stops today as the  company unveils its first N-Lens series device in Beijing. We're looking  at a 1.7GHz quad-core Snapdragon 600 phone with a 5.9-inch 1080p  display, an "O-Touch" backside touch panel (for scrolling and taking  photos) and a generous 3,610mAh battery, but the focus is obviously on  the camera. Not only do you get a 13-megapixel imager with an f/2.0,  6-element lens plus dual LED, but it's also rotatable over 206 degrees!  While THL's W11  beat the N1 to being the first phone with both a front and back  13-megapixel cameras, it's not as versatile as the latter's  implementation, and it's ultimately all about the image quality.
In case you're wondering, Oppo said the N1's swivel camera has passed  a 100,000-time rotation test, which works out to be seven years of  usage if you rotate it 40 times a day. This is quite reassuring, given  that you can also activate the camera -- which takes just 0.6 seconds --  with a rotation of over 120 degrees. Oppo also boasted that its  camera's been tested in over 100 scenarios, which is apparently the  highest in the industry. Other features include long exposure of up to 8  seconds, an updated version of Oppo's beautification algorithm, and  support for video beautification in China's popular IM app, QQ
