A hardware wallet is not fully mobile-compatible merely because its companion app appears in the App Store or Google Play. The useful question is whether your complete signing workflow works on your exact phone.

Break the test into tasks. Can you connect or pair the physical signer? Can you create an account, view balances and generate a receive address? More importantly, can you verify that receive address on the trusted hardware display? Can you build a transaction, inspect its destination and amount on the device, approve it, reject it and confirm that the rejection behaves correctly?

Then test the activities that generic compatibility pages often hide. Check your required chains, tokens, staking flows, multisig coordinator, browser wallet and DeFi applications. Verify whether firmware updates, app installation and recovery checks can be completed from the phone or still require a desktop. Repeat the matrix separately on iOS and Android because the same wallet model can expose different capabilities on each platform.

Treat connection method as only one row in the matrix. Bluetooth, USB-C, NFC and QR can each support a usable workflow, but none proves that every asset or transaction type is available. What matters is the tested path from phone to trusted display to signed transaction.
