The OxygenOS, an in-house ROM based on the popular Android 5.0 Lollipop operating system, from OnePlus was initially scheduled to be released on February 12. However, the company did not reveal any information regarding the launch of a CyanogenMod substitute and just introduced the team working behind the ROM. There have not been any updates regarding the launch of the CyanogenMod 12S either.
However, the co-founder of OnePlus revealed that both – the CyanogenMod 12S and the OxygenOS – will be bringing the Android 5.0 Lollipop experience to the OnePlus One users sometime next month. Without being too specific on the release date, he added that it is likely to be out by “till mid to late March”.
He also added that the primary reason for missing the 90-day update window was the lack of stability in the alpha nightly builds which already exist for both OS builds.
