Samsung Galaxy Note 7 Spec Leak Reveals Iris Scanner Limitations

The Samsung Galaxy Note 7 is expected to include an iris scanner as its standout feature. While recent leaks have revealed screenshots of how the feature will work, new settings screenshots detail possible limitations for the component. Similar to how fingerprint scanners may not work as well if a user has wet hands or if their finger is not placed directly on the sensor, there are several instances, for which the Galaxy Note 7’s iris scanner may not recognize a user's’ eyes.

Some limitations for the Galaxy Note 7 iris scanner include wearing glasses, sun shades, color contact lenses or circular contact lenses. Problems could also arise if a user has had Lasik surgery or attempts to scan their irises in an area with too much light or insufficient light.

Prior leaks have shown that the Galaxy Note 7 iris scanner is essentially a camera sensor that captures an image of a user’s eyes, then analyses their irises to authenticate the device. Proper protocol for the iris scanner indicates users must hold the Galaxy Note 7 handset 25-35 cm away from their face and then align their eyes with the circles on the setup screen. However, many of the features limitations to make sense.

While the iris scanner feature for the Galaxy Note 7 is not yet official, there are several indications that it will be confirmed upon launch. Samsung teased the feature in the press invites to its Aug. 2 Unpacked event, where the Galaxy Note 7 is expected to be announced. The invite includes an blue icon with one white fleck, which looks similar to an iris.
