Ledger Flex Review
Ledger Flex is a premium touchscreen Ledger signer for users who want clearer transaction review, iOS and Android connectivity, NFC recovery-key support, and broad Ledger ecosystem features, but it is expensive and still depends on Ledger's proprietary firmware trust model.
Pair with a backup signer
Many touchscreen Ledger users keep a separate offline Nano X as a backup cosigner or spare device — different form factor, proven Bluetooth mobile signing, and a separate seed if you want redundancy.
