USB-C Shape Does Not Establish USB Host Support
If Ledger Live reports Android USB OTG not supported, confirm that the phone can act as a USB host for the intended Ledger connection. Ledger Wallet is the app’s current name. A USB-C socket can charge a phone without proving that the required host and data workflow is available.
The Android USB host overview explicitly distinguishes host support and application permission. Hardware capability, the cable arrangement and app compatibility all matter; an adapter cannot add a missing platform feature by changing connector shape.
Check the Phone and Ledger Combination
Read the phone manufacturer’s specifications and current instructions for USB host or OTG use. Some phones expose an OTG control; others do not. Do not search indefinitely for an identical toggle shown on a different brand or assume that every Android model implements the same connection behavior.
Confirm that your Ledger model and intended task are supported on Android. The Nano S Plus specifications describe its wired Android connection. It has no Bluetooth and no internal battery, so wireless pairing is not a fallback for that model.
Build the Simplest Appropriate Data Path
Use a compatible data-capable cable or OTG arrangement with the correct host role and connectors. Remove unnecessary hubs and adapters for the first test. A cable sold only for charging is insufficient, and several adapters can make it difficult to identify which segment failed.
Ledger’s smartphone connection instructions provide the publisher’s transport guidance. Follow the procedure for your hardware rather than changing Android developer options or installing an unknown USB driver app.
Interpret Power, Detection and Permission Separately
| Result | What to check next |
|---|---|
| The Ledger does not power on | Host capability, power and physical cable arrangement. |
| It powers on but Android never detects it | USB data conductors, host role and compatibility. |
| Android detects it but the app cannot open it | App handling, device permission and competing clients. |
Unlock the Ledger through its physical controls when prompted. Do not treat an illuminated screen as proof that Android has delivered a usable device session to the application.
Choose a Supported Alternative When Necessary
If the phone lacks the required wired path, use another compatible Android host or supported desktop setup with the same configured Ledger. A Bluetooth-capable Ledger model can have a different supported mobile route, but that does not change Nano S Plus hardware capabilities.
Keep the existing wallet configuration intact. Moving the companion interface does not require entering its recovery phrase into a phone, cable utility or web page. An iPhone USB-C port should not be assumed to provide the equivalent Android wired Ledger workflow.
If the phone recognizes another USB accessory, note its type rather than describing OTG as completely proven. A storage device, charging accessory and Ledger can exercise different interfaces. The useful comparison keeps the same phone and intended wallet workflow while changing one appropriate cable or supported host. Record which part of that comparison actually changed the result.
USB OTG Questions
Does a working USB flash drive prove Ledger support?
It shows that some host behavior works, but storage and a hardware-wallet interface are different device classes. Continue checking the actual Ledger model, permission request and application support.
Can I reconnect during a firmware installation?
Do not interrupt progressing Ledger OS installation to compare cables or OTG settings. Use the supported update procedure and complete it before ordinary hardware experiments.
What details help support?
Provide the phone, Android release, app version, Ledger model, exact cable arrangement and the furthest detection stage reached. No recovery words or device PIN are needed for that assessment.
