Device maker OnePlus said it is “surprising and disappointing” that its Android platform partner, Cyanogen, had inked an exclusive deal with Micromax for the Indian market.

OnePlus worked to launch its OnePlus One device (pictured) in India this week, and said that it and all of its partners, including Cyanogen, had “put countless hours of work into making this launch a success”. According to some reports, while the device will still be available, it will not see any future updates.

OnePlus has already built up its own in-house platform expertise, initially to build software for future devices, but it has now “shifted engineering efforts to the OnePlus One”, and is promising a production-ready build in February 2015. This is promised to be a light customisation of Android: “We have no plans of departing from Material Design nor adding unnecessary customisations,” the company wrote.

With Cyanogen’s platform, CyanogenMod, powering OnePlus devices in other markets, the vendor also said that “Cyanogen has unequivocally committed to continuing this global support and we look forward to working with them for another year on continuously improving our device”.

OnePlus and Cyanogen announced a partnership in January 2014, to integrate the CyanogenMod platform with OnePlus hardware, with the introduction of some new features alongside. OnePlus One debuted in April, alongside CyanogenMod 11S, which was described as “a special release tuned to take advantage of everything the One has to offer”.

In November, Micromax and Cyanogen announced a partnership for a new device line, called Yu. It will retail online only, looking to echo the models of companies such as Xiaomi.

While Micromax is a significant player in the Indian market, and Yu is likely to see some heavy promotion, it would not be surprising to see OnePlus now looking to speed the shift to its own platform globally, as well as for the Indian market.

Other vendors are also likely to take a careful look at Cyanogen Mod, if it is prepared to give exclusive rights to large markets – seemingly without discussion with existing partners.
