Now that Samsung has set the official date for their next Unpacked event this year, which is slated for August 2nd in New York, this is largely the expected date for when Samsung is going to unveil the next generation Note device, the Galaxy Note 7. While Samsung have not confirmed this, the invites that were sent out to press heavily suggest this to be the case. Leading up to its announcement and throughout this year there have been a number of leaks about the Galaxy Note 7 concerning many of its potential hardware specifications, along with leaked renders of the final hardware design. One of the heavily discussed rumored specs is the inclusion of the iris scanner which would give users the means to unlock the device using their eyes and the integrated component.
Most recently, the iris scanner showed up in an alleged leaked image of the Galaxy Note 7, further suggesting that Samsung was indeed going to manufacture this device with an iris scanner installed in it. Further back and towards the end of December of last year the initial rumor for the iris scanner inside of the device popped up, and as of today a new leak of the import data for the Galaxy Note 7 seems to show that the iris scanner will be a part of the device hardware features.
The Zauba listing, which can currently be seen, lists off the words "iris cam" prior to the model number SM-N930F which is one of the model numbers for a Samsung Galaxy Note 7 variant. Although the origin country is listed as Vietnam, it's highly unlikely that, if the device does come with an iris scanner on any model it's a safe bet that it would be present in all models that are aimed at separate regions. Another detail worth mentioning is that the import data logs detail that 2,000 units of the device have been shipped out to the region, which suggests that the iris scanner is more than just a potential test feature as that many units with an "iris cam" would likely only be included if Samsung were planning to make it a permanent piece of hardware that hits the final production model of the handset.
