How could be it secured? I'm just ask if Samsung brand produced by korea could be invulnerable to the hackers but it seems it's a great steps on some big company on trust to bitcoin and i hope others big company could create something bigger on that idea.
It seems like their in-built wallet makes use of a system they call Samsung Knox [1], which secures private keys by managing application privileges [2] and ensuring the integrity of said application privileges by verifying the boot process on the hardware level [3]. So to my understanding while private keys are probably encrypted they are not stored in a secure hardware element as is the case with common hardware wallets such as the Trezor or Ledger. Samsung Knox's track record is not exactly splendid [4][5] but I guess we'll see in the next few months whether they have brought their shit together.
