Hi guys,
I've recently bought an refurbished Samsung Galaxy GT-I9100 really cheap with intentions to use it as a cold storage wallet. I mean, uninstall all applications already present, install Electrum (apk) and never allow bluetooth or wi-fi (SIM card already removed). My intention is to use my everyday regular phone to watch this wallet and create transactions to be signed by this other offline one (I'd use the camera to read the generated QR-code). My susprise was to find out that Electrum's Android version cannot sign transactions. Is there a way to get this to work? Thank you buddies.
yes it can sign transactions.
you need to scan the unsigned transaction with the camera, and it will open a transaction window with a sign button.
