Last month, YU Yureka received a stability update to improve battery performance, but it could not fix other bugs.

Now, the company's official mobile software partner CyanogenMod has released the first nightly version of CM12.1 OS based on the latest Android 5.1 Lollipop series OS to the Yureka.

Though this nightly update is unstable, it will not house any major bugs and only benign glitches will be found. These issues will be fixed promptly by Cyanogen developers as they will release regular updates.
