Samsung S25 + YubiKey USB-C + Microsoft Authenticator issue
When using a YubiKey USB-C with Microsoft Entra ID on a Samsung S25, Microsoft Authenticator seems to freeze after touching the YubiKey.
After pressing the gold button:
- PIN input dialog appears, but the keyboard never shows up
- phone becomes warm
- battery drains quickly
- phone becomes sluggish
- login cannot continue
YubiKey detection over USB-C works in Edge, so the issue seems related to Microsoft Authenticator handling the security key flow.
Anyone else seen this on Samsung S25 or Android?
