Cyanogen CEO Steve Kondik wrote on his Google+ account in answer to a OnePlus fan that the CyanogenMod 12S will realease by OTA until April 10th.
OnePlus users are frustrated with the delay of the CM12s for their device, but the delayed has occured because Cyanogen had submitted a new version, and in the same day was released a new test suite that delayed the update.
(…)Seriously though, a new test suite came out because of MR1 literally the same day as we submitted, and so we had to redo the whole process with the new one.
An user questioned if the CM12S certification would be completed within 2 Days or sooner?, to which, Kondik replied:
Should be. Takes about 4 days. Once it’s out I’ll probably write up a retrospect on everything that’s gone down along the way.
So there you go, CM12S for OnePlus should be available this week, hopefully on or before April 10th. However the Oxygen OS is already available to the OnePlus One.
