How to use Trezor on Android devices? (Mobile setup)

Android App Installation Process

1. Open the Google Play Store on your Android device.

2. Search for “Trezor Suite” using the search bar.

3. Locate the official application published by SatoshiLabs and verify its developer signature.

4. Tap “Install” and wait for the download and installation to complete.

5. Alternatively, visit trezor.io/download directly in your mobile browser and select the Android APK option.

6. Enable “Install unknown apps” permission for your browser if prompted during APK installation.

7. Confirm the installation and launch Trezor Suite after completion.

Hardware Connection Requirements

1. Ensure your Trezor Model T or Model One is powered on and unlocked with its PIN.

2. Use a USB-C to USB-C cable or a USB-C to USB-A adapter with OTG support depending on your phone’s port configuration.

3. Connect the hardware wallet to the Android device — the Trezor Suite app will detect it automatically upon successful handshake.

4. If detection fails, check whether USB debugging is disabled and confirm no third-party security apps are blocking device access.

5. A green checkmark and device name appear in the app interface once connection is validated.

Wallet Initialization Steps

1. Launch Trezor Suite and tap “Create new wallet” if setting up for the first time.

2. Choose between standard 12-word or advanced 18/24-word recovery seed options.

3. Carefully write down each word in exact order on physical paper — digital capture is strongly discouraged.

4. Confirm the seed phrase by selecting words in randomized order as prompted by the device screen.

5. Set a unique 4–8 digit PIN code directly on the Trezor hardware display — never enter it on the phone.

6. Assign a custom label to identify the wallet within the app interface for future reference.

Transaction Signing Workflow

1. Within Trezor Suite, navigate to the “Send” tab and enter the recipient’s address and amount.

2. Select the correct cryptocurrency and network fee level before proceeding.

3. Tap “Continue” to generate the transaction preview — this data is sent encrypted to the hardware wallet.

4. Review all transaction details including destination, amount, fees, and change address directly on the Trezor screen.

5. Confirm approval using the device’s physical buttons — no approval occurs without manual hardware interaction.

6. Once signed, the transaction is broadcast to the blockchain via Trezor Suite’s relay nodes.

Frequently Asked Questions

Q: Can I use Trezor Suite on Android without installing any additional drivers?A: Yes. Android devices running Android 8.0 or higher handle Trezor communication natively through WebUSB without external drivers.

Q: Why does my Trezor Model One not appear in the app even after connecting?A: This commonly occurs when using non-OTG-compliant cables or when battery-saving modes restrict USB peripheral access. Disable battery optimization for Trezor Suite in system settings.

Q: Is it safe to store my recovery seed inside Trezor Suite’s mobile app?A: No. The app never stores or displays the full seed phrase. Recovery words are only shown on the hardware device screen during setup or backup verification.

Q: Does Trezor Suite for Android support hidden wallets (passphrase protection)?A: Yes. During wallet creation or login, users can enable an optional passphrase — which generates a completely separate wallet derivation path secured by the Trezor hardware itself.
