Because this device runs an older version of Android, it may face security compliance issues or “App Version” expiration on Microsoft Teams. If you are seeing a “Company Portal” error or sign-in loops, it is likely due to the hardware reaching its software support limit.
Would you like me to find the firmware version requirements for Microsoft’s 2026 security standards for this model?
