Following the launch of the OnePlus 3, the firm's chief executive Pete Lau has stated that it will not create a follow-up model to 2015's OnePlus X. Speaking at the OnePlus 3 launch event in Shenzen, Lau said that the company would instead focus on "true flagship" models rather than continuing to diversify its portfolio. He indicated that while last year's OnePlus X was a worthwhile experiment, and one that was relatively well received, the company needed to concentrate on having a solid foundation with its flagship line, adding that in being distracted by the OnePlus X development last year that's something that arguably wasn't achieved with the OnePlus 2.
Lau also commented that OnePlus plans to bring its seperate software development projects closer together; that's Oxygen OS for the global market, and Hydrogen OS for the Chinese market, both of course based on Android - he said there would be announcements on this subject in late 2016. It's worth noting that Oxygen OS is quite a lightweight OS on Android while Hydrogen OS is heavily skinned and modified, so it's not clear what kind of overlap there might be with the two being pooled to some extent, although for what it's worth it was definitely not implied that the two systems will be merging.
In the last 12 months or so OnePlus has also introduced several integrated services, such as its device insurance scheme; Lau said the company plans to go further in this vein with more services for customers, as well as more lifestyle products.
