We have heard many rumors in the past that claimed Samsung would introduce retina scanners in its mobile devices. So far it hasn’t done that though it did add a fingerprint scanner to the Galaxy S5. This September the company is due to unveil the Galaxy Note 4. If a tweet by one of Samsung’s official Twitter accounts is construed as a hint then its possible that the upcoming flagship phablet might feature a retina scanner.
Theoretically a retina scanner would be a major improvement for mobile device security. As has been demonstrated multiple times it is not exactly that hard to fool a fingerprint sensor, a widely known method works with both iPhone 5s and the Galaxy S5. A retina scanner would not grant access unless the device owner scans his or her retina.
In a tweet the official @SamsungExynos account posted an image of a smartphone with focus on the user’s eye. The accompanying caption reads “Security can be improved using features unique to us.” It may very well be a subtle hint towards what would arguably be one of the biggest features of the Galaxy Note 4.
Other rumors suggest that the Galaxy Note 4 is going to have a 5.7-inch Quad HD display as well as a Qualcomm Snapdragon 805 processor with Adreno 420 graphics processor and 3GB of RAM. Samsung is expected to unveil the Galaxy S5 at IFA 2014 in Berlin this September.
