OPPO did reveal the the OPPO N3 today, but that wasn't the only thing it had in store. Aside from a new roster of accessories, the Chinese OEM also announced the OPPO R5 to the crowd as well. Both are intriguing smartphones, especially if you're in the Chinese market. The OPPO N3 turned out to be everything we gathered it would be, auto-rotating camera and all. The OPPO R5, on the other hand, has just probably successfully claimed one of the most coveted title of all: the thinnest smartphone in the world.
