Intro: Ledger Flex OS 1.5.1 shipped on 2026-01-21. The release focuses on Bluetooth handshake stability, app launch responsiveness, and clearer error messages — aimed at users who've seen occasional connection pauses or slightly slower UI loads.
Version changes: Bluetooth handshake retry cadence tuned, reducing "waiting for device confirmation" dwell time; app-manager initialisation path streamlined, so older batches reach the main UI slightly faster.
Compatibility: Extra guard paths for the latest Ledger Live log interaction to cut duplicate popups; a handful of error-code translation gaps corrected for consistency.
Notes: Keep battery topped up and update only through the official channel. The update will never ask for the recovery phrase. In heavily-interfered wireless environments, temporarily switching to USB is a viable workaround.
What's next: Ledger will continue monitoring FIDO-module and power-usage metrics, and encourages users to submit diagnostic logs describing connection experience after the update.
Safety reminder: We will never ask for your recovery phrase, PIN, verification codes, or private keys. Anyone requesting them is attempting fraud — do not share and do not proceed.
