Sure, when trying to use the bridge on samsung phones it never sees the apex flex as a full passkey as it does with another reader such as the ACR122u. I did a whole battery of tests to try to get this working here: Vivokey Apex Flex Android FIDO2 Issues - #9 by gatsu referenced from you response to this post here: VivoKey releases NFC Passkey Bridge - #84 by gatsu The implant works perfectly fine for U2F on android but nothing with resident keys even when using the bridge. I actually seem to have more stability in doing U2F through the built in android NFC feature than even trying to do U2F via the bridge.
After upgrading my phone to android 16 the issues persist. I highly suspect this is just a quirk or some sort of software issue samsung does with their crappy OS tweaks.
