their preloaded wallet app is closed-source as well, right? So good news for adoption, bad news for the sake of open-source and decentralization..
Yes, their Samsung Blockchain Wallet is closed source software, and Samsung is biggest Apple competition so if they ever made their own hardware wallet like I suspect, it will probably be closed source propriety device.
They only think about profits so why support other hardware wallet devices for Samsung phones when you can make your own and earn extra money from that.
