Nokia X Software Platform was based on the Android Open Source Project (AOSP) and the Linux kernel. Nokia combined Android apps with Nokia experiences (such as HERE Maps, Nokia Xpress and MixRadio) and Microsoft services (such as Skype and Outlook). Nokia officially described the software as bringing “the best of all worlds”. It also encompasses features from the Asha platform, such as the Fastlane notification centre. The user interface mimics that of Windows Phone.
The OS has been compared to Amazon.com's Fire OS, which is also based on AOSP.
