About
Nokia X is a customized platform built on the Android Open Source Project (AOSP), the software stack upon which some of the most popular smartphones in the world are based.
The core Nokia X platform is built on AOSP v4.1.2, which supports android API level 16. On top of this, Nokia has added a number of frameworks which are close equivalents to the proprietary Google Android frameworks, such as for maps and inapp billing.
As of Mid-July 2014, Microsoft who now own Nokia smartphones, are discontinuing all Android based devices in the Nokia X line.
