 The iris scanner's implementation was panned for adding additional steps to the process of unlocking the phone in comparison to the fingerprint reader, and that it does not integrate into Android's integrated authentication platforms (making it proprietary to Samsung components).Warnings regarding looking at the sensor for too long were also considered to be "just a little scary".TouchWiz on the Note 7 was panned for consisting mainly of "'different for the sake of being different' changes that don't add much to the software experience", and make the interface less consistent with third-party software by removing elements of Material design language.
