It is always natural with our memory that new things replace older from our mind. Same happened with Oppo N1 that was pushed out of scene by Oppo Find 7 and the users forgot about their favorite device. A trusted source says Oppo is planning to launch original N1 in mini version and next model of original N1, under the name N2. The previous N! was equipped with a camera with 13MP capacity that could rotate and work as front and rear cameras.
The new Oppo N1 mini is likely to be equipped with a 5 inch screen, resolution not know yet. It is called mini because of relatively smaller screen. N! had 5.9 inches whereas mini is supplied with only 5 inches. As the hearsay, the N1 mini will be having a better octa-core MT6592 chip or the octa-core Exynos 5422 chip. There will be two versions; one with supporting LTE connectivity while the other is without LTE connectivity.
Taiwan origin source that talked about Oppo N2, does not have much of information and is only expressing their guess with anything specific and in clear terms.
