Samsung's upcoming flagship, the Galaxy Note 7, is due to be launched on 2 August and amid pre-launch leaks flooding the internet, another photo leak on Weibo has emerged showing how the iris scanning technology will work. The Galaxy Note 7 will be the first commercial device from Samsung to have the iris scanning technology on board.

The pictures leaked on Weibo and accessed by SamMobile show how the iris scanning option will appear on the home screen when a user wants to unlock his/her device. Like fingerprint scanner enabled phones provide both options for pattern unlock as well as fingerprint scanning, the leaked images show the Note 7 will provide users with the option to unlock the phone either by scanning their iris or by the same old pattern lock.

The feature works in a way similar to a laptop's face recognition technology but given the size of the device is smaller the iris scanning is expected to be more precise. The user is supposed to hold the device at arm's length (approx 25-35 cm away) from his or her face with the screen facing towards them and needs to position their eyes in such a way that they point directly towards two circles shown in the photo. If the match is correct it will automatically unlock the phone.

As of now it is not known if the phone will also have a fingerprint scanner but it seems less likely since they are introducing the iris scanner which is a more advanced version of bio-metric authentication.

The Galaxy Note 7 is expected to feature a 5.7-inch QHD curved Super AMOLED display, a 12-megapixel primary camera and a 5-megapixel secondary camera. The processor is likely to be a Snapdragon 820 or 821. The RAM capacity of the phone has been speculated to be 4GB by some and 6GB by others. The Note 7 is also slated to be the Korean giant's costliest smartphone ever.
