OPPO launched the Reno5 Pro+ recently as its first smartphone that is powered by the latest Snapdragon 888 chipset. It comes with an electrochromic rear and a 50MP Sony IMX766 lens built in partnership with Sony. Now, it seems like the Chinese company has plans to upgrade the camera features of its upcoming flagship as the latest leak states that OPPO and Sony are also working on a custom chip named Sony IMX789. We could see it on the OPPO Find X3 series.
