On its Samsung Exynos Twitter account, the Korean company tweeted an image teasing the future of its chipset with a sly image. In it, we see a large smartphone with an eye in the middle and a scanner-like circle around it. While no specifics were given, this might indicate the upcoming Galaxy Note 4 will include retinal scanning.
The tweet includes the hashtag #ExynosTomorrow, and reads, "Security can be improved using features unique to us. That's what we envision. What would you use?" The seemingly obvious hint is that Samsung has cooked up a security feature involving one's eye (like an iris scanner).
Of course, the lack of details means the image could be hinting at any number of things. Still, if the retinal scanning security assumption is correct, it would follow in line with past talk of Samsung and the use of biometrics (fingerprint scanners included).
The Galaxy Note 4 is expected to make its appearance in the coming months, and with it could come the inclusion of eye-scanning security technology, in whatever form that may take. All is speculation at this point, but we'll know one way or the other soon enough.
