Yeah that link in my last response has chrome and firefox tested. This may be an issue with Samsung phones in general especially if Amal isn’t having the same issues as in that chart. I’d love to dig into this and get the bridge working as a viable drop-in to fill the gaps that android is lacking at the moment. Especially since Samsung is 30.8% of the android market share #ref.
The marketer in me also suspects that filling this gap could seriously boost the sales and visibility of Vivokey as a brand as the annoyed users of yubikeys are frequently complaining about this as well https://www.reddit.com/r/yubikey/comments/1lyf2z0/fido_2_passkey_nfc_prompt_not_working_on_android/ and they should in theory also be able to use this app. This momentum could be awesome growth for vivokey, at least until android implements the function in the core OS.
