The Samsung Galaxy S5 had some serious sensor upgrades at launch, but it just might pale in comparison to the Note 4. Samsung’s Exynos Twitter account Tweeted out a photo of a phone with an eye being scanned. “Unlock the future,” it says. The caption on the Tweet itself reads: “Security can be improved using features unique to us. That’s what we envision. What would you use? #ExynosTomorrow.”

Earlier Samsung Galaxy S5 rumors suggested that particular device would have retinal scanners, though it obviously didn’t. This revelation confirms that Samsung didn’t stop thinking about it, though, so perhaps it just wasn’t ready for prime time. What are the chances it’s ready for the imminent release of the Note 4? Think we’re ready!?
