The Oppo N1 mini is expected to feature a 5 inch screen of unknown resolution. The original Oppo N1 has a 5.9 inch glass, so in this case there is nothing wrong with calling a 5 inch phone a "mini". According to the rumor, the N1 mini won't be a slouch in the processor department. It will feature the octa-core MT6592 chip or the octa-core Exynos 5422 chip under the hood. There will be a variant of the phone with support for LTE connectivity, and one made without LTE support.
As for the Oppo N2, apparently we finally found something that the Taiwan based supply chain doesn't know that much about. Outside of claiming that it is in the works, the tipsters had no specs to report about the sequel to the Oppo N1.
Thanks for the tip!
