The R9 and R9 Plus from Chinese smartphone maker Oppo may have slipped under your radar, but plenty have paid attention to the phablet duo. In fact, after just six months on sale, the R9 series is reported to have chalked up a whopping 20 million unit sales. An impressive figure for a pair of mid-to-high-enders, Oppo is said to be preparing another handset called the R9S, which has now been certified by China's CCC.
The device also gained TENAA approval back in August, which suggests a roll-out could be on the cards very soon. Unfortunately, neither the TENAA nor 3C certification offers much to go on by way of specs.
For the meantime, we do have some rumored info on the device. The R9S will apparently follow the R9's lead with a 5.5-inch 1080 x 1920 display, while Qualcomm's Snapdragon 625 chipset could displace the MediaTek Helio P10 of the standard R9. One of the key selling points of the R9 and R9 Plus is the 16-megapixel selfie camera, which will likely be a feature of the R9S along with a 13-megapixel main shooter.
The rumor mill pits the battery at 2850 mAh boosted by Oppo's Super VOOC charging tech as demoed earlier this year at Mobile World congress. There's no mention of RAM, but it's seemingly doubtful that the R9S will see less than the 4 GB offering of the R9.
We'll have more on the Oppo as it heads for a probable October launch, so stay tuned.
