Yu’s CyanogenMod-running Yuphoria phone, sold primarily to the Indian market, has CM12.1 (the customized version of Android 5.1) available for almost half a year now. The catch is that it’s been available as a CyanogenMod nightly build, requiring end users to flash a custom recovery, then a custom ROM in order to access it. Yesterday the Cyanogen company and Yu itself announced the over-the-air rollout of the finished, consumer-ready update for the stock software build.
