In order to transmit several specific values from mobile devices like brand, os, type, ... it seems to be legit to use uadata. There is an issue started at https://github.com/donni106/matomo-tracker-react-native/issues/13 about that topic, where values are undefined and presented as unknown in Matomo.

Is there a way to enrich the data per uadata or what are the correct params to use?

Hi @donni106. Thanks for creating the issue. Guess we could improve the documentation around that.
The javascript tracker code to gather the data is located here:
https://github.com/matomo-org/matomo/blob/2c63f2726077b57275ee0d74a1f0c9ac2a147529/js/piwik.js#L3070-L3088
The values send with uadata then are checked with device detector. So it's not possible to send through random values, as they might get ignored then.
