The OnePlus One currently ships with CyanogenMod (CM). The latest build, CM 12S, will arrive on or before March 30 as an over-the-air (OTA) update.
OnePlus will release its own Lollipop-based ROM, dubbed OxygenOS, by March 27. The company said its updates were delayed by an unforeseen OS signing issue, as well as an unstable camera module.
It’ll be interesting to see how OnePlus’ own ROM is received. It may not be available as an OTA update when it launches, so there’s a chance that many users won’t try it.
However, if OnePlus’ forums are anything to go by, its fans are a savvy, loyal bunch who will definitely want to get a taste of the company’s new offering — even if that means flashing a new ROM manually.
