At least according to research firm Counterpoint

The fight for smartphone supremacy in China, the world’s biggest market, has just taken an interesting turn. According to research firm Counterpoint, OPPO has managed to come out on top for Q3 2017, muscling out other contenders like Huawei, Vivo and Xiaomi for the top spot.

OPPO shouldn’t be celebrating too hard just yet – they have the thinnest of margins in terms of marketshare over their two other rivals, coming in at 18.9%. Both Huawei and Vivo are tied at second place with 18.6%, while Xiaomi is in fourth with 13.8%. Apple rounds out the top 5 with 10%.

Counterpoint credits OPPO’s success to their R11 smartphone, which helped them edge out their competitors in Q3 of 2017.

“Compared to last year, where OPPO and Vivo were the fastest growing brands in China with volumes up 109% YoY and 78% YoY respectively, growth for these two brands has slowed down this quarter. Nonetheless, the two brands are still growing at a healthy rate and have closed on the previous quarter’s leader, Huawei. OPPO’s R11 was the bestselling model overall, which helped OPPO edge just ahead of Huawei during the quarter,” said James Yan, Research Director at Counterpoint Research.

Xiaomi’s a little behind the top three contenders, but it’s growing faster than the three players.

“Xiaomi made a strong comeback, as its shipments grew 32% annually driven by strong demand for its Redmi 4X series at the low-end and Mi 6 at the high-end. Xiaomi’s strong recovery can be attributed to a streamlined supply chain and being more effective in securing key components. Additionally, Xiaomi has focused on expanding its offline distribution channel under the Mi Home brand, expanding its total addressable market,” said Counterpoint’s Research Analyst Mengmeng Zhang.
