The Oppo N1 was introduced in September 2013 and was notable in particular for the rotatable camera module and the touch panel on the back of the device. The camera makes a second front camera obsolete and allows self-portraits with 13 MP resolution. The rear touch panel allows user gestures, such as scrolling, without touching the screen. Moreover, the N1 is the first smartphone that comes in a limited edition with the wildly popular custom ROM, CyanogenMod, pre-installed. Oppo N1 is the first hardware partner of the new company CyanogenMod Inc.
