Hi,
that means that device is currently not in a Cardboard device database.
Can you provide information about your Samsung Galaxy S8+, then I can try adding it?
The user-agent and the real screen-sizes would be required to be know. According to a web-research the device name should be 'G955F' but seeing real and verified data would be better of course.
Btw - what do you mean with 'Even with the mobilevr_database_url defined, nothing seems to change'?
Have you set a link to custom database where the S8+ is listed?
Because when mobilevr_database_url is not, the
https://dpdb.webvr.rocks/dpdb.json database will be used by default (see here -
mobilevr_database_url) and in that database there is currently no entry for 'G955F'.
Best regards,
Klaus
