Description
Returns the platform-specific unique device id, replacing the deprecated GetUniqueDeviceId. Commonly used for analytics or device-based save data.
Caveats & Gotchas
- • The format and stability of the returned id varies wildly by platform — some platforms return a hash that changes on OS reinstall, others return a hardware-tied value; don't assume it's permanent or globally unique.
- • On some platforms this id can be considered personally identifying data, so check platform certification/privacy requirements before sending it to analytics services.
