The iris unlock is amazing on my phone its so cool and fast!! i dont actually know that at what levels it is different from the face unlock but its still pretty dope.. I hope Samsung will working on it & some efficient updates 😊😎
Samsung always provide best security features on galaxy devices like knox software. iris scan is really unique feature developed for galaxy devices and face unlock is so old feature i use it on my tab 2. face unlock less secure and slow then iris scan.
