The source goes further, suggesting that Samsung and its hardware partners already have production facilities set up. Apparently located in Tianjin, China, the facility will take care of the 12MP unit's mass production (the Note line is quite popular). According to the report, further investments into the factory could allow for a yield of as many as 3 million units a month, which would satisfy demand for the new Samsung phablet. Lastly, the source claims that a 3.7-megapixel front-facing camera is what the Note 4 will have on board.
