    Why Compatibility Differs

    Meta Horizon OS is built on AOSP (Android Open Source Project) but:

    • No Google Mobile Services: Quest doesn't include GMS
    • VR-specific permissions: Different permission model
    • Missing hardware: No GPS, cellular, or telephony hardware
    • Custom APIs: Meta provides VR-specific alternatives
