My Android one phone got Android Lollipop 5.1 update.

I bought Karbonn Sparkle Android one installed with Android Kitkat version 4.4.4 recently. Yesterday it got Android version 5.1 update which is called Lollipop.
If you click on Settings/About_phone/Android_version_5.1 number of times it opens Lollipop game (Screenshot below)
