      Description

      The support for different features in Qt differ between Android and iOS, forcing specific code to be written for the two platforms. We need to look into the differences and align the functionality, and hence remove the developers' need to write platform specific code.

      The most important differences are currently in:

      1. Qt Bluetooth
      2. Qt NFC
      3. Qt Sensors
      4. Qt Multimedia

      By looking at the documentation, these seems to be the top-level areas of divergence:
