Compare Screen Lock With App and Device State
When Ledger Live disconnects as the iPhone screen locks, first reproduce the difference between a foreground session and a locked or backgrounded one. The app is currently called Ledger Wallet. The observation can involve phone app lifecycle, hardware locking, power, or a saved pairing that reconnects poorly; it is not automatically proof that Bluetooth hardware failed.
Keep the comparison read-only where possible. Do not use repeated sends as a connectivity test, and do not disable phone security permanently to preserve a session you have not yet diagnosed.
Build a Controlled Foreground Comparison
With the phone unlocked and the app visible, connect the charged Ledger nearby and perform a simple device-dependent action. Note whether it remains available while you read both displays. Then observe the symptom associated with the phone’s normal lock behavior without submitting a payment.
Record whether the Ledger itself locked or powered down during the same interval. If both screens changed, the iPhone lock is not the only variable. Unlock each normally before testing reconnection.
Apple’s Bluetooth permission reference helps check the app’s authorization, but permission alone does not promise a continuously active background wallet session. Likewise, turning on unrelated background settings is not a documented universal cure for every Bluetooth interruption.
Determine Whether Pairing Survived the Interruption
After unlocking, reopen the intended app action and see whether the existing association reconnects. A valid saved relationship may not require a new code. The phone displaying the Ledger in system settings is weaker evidence than the app completing an actual hardware request.
If reconnection works normally, keep the app in the foreground while reviewing or approving device-dependent actions. This practical result differs from a session that cannot reconnect at all. Report those outcomes separately instead of repeatedly deleting pairings after every ordinary idle period.
If it does not recover, use Ledger’s model-specific Bluetooth troubleshooting. Check power, radio state, current supported software, and competing phones before a coordinated pairing rebuild. Resetting pair records is not resetting wallet secrets.
Handle Interrupted Financial Work Carefully
If the screen locked after transaction approval, retain the chain hash or provider order reference and inspect its status before another payment. Losing the interface does not establish that the approved request was never accepted elsewhere.
Review any draft presented after reconnecting from the beginning. Do not assume recipient, amount, fees, or contract permissions remain identical merely because the workflow resumed. Hardware-screen verification still applies.
Keep Maintenance and Privacy Protected
A progressing Ledger OS installation must retain its supported host session and connection. Do not reproduce lock-related disconnects during active firmware work or clear app data while it proceeds. If maintenance failed, resolve that state with the exact hardware instructions first.
Keep the recovery phrase offline. Neither a lock-screen disconnect nor a Bluetooth rebuild requires typing it into iOS. If support needs evidence, provide versions, timing, model, and whether the hardware also locked, not backup photographs.
For a practical comparison, observe one idle connection with the phone awake and another after locking it. Record whether only the app session ends or the hardware itself powers down, because those outcomes suggest different checks.
Screen-Lock Questions
Should I Turn Auto-Lock Off Forever?
No. Diagnose the behavior and keep the app visible during the relevant action. Permanent weakening of phone privacy is not a general session-repair procedure.
Does Face ID Reconnect the Ledger?
Phone or app biometric access and Ledger communication are separate. Unlocking the interface does not prove an active device session or authorize a transaction.
Can I Use USB on iPhone Instead?
The current supported iPhone route uses compatible Bluetooth Ledger models. A cable is not the Android-style wired fallback for this workflow.
