ZTE Blade S6 was released earlier this year, but was missing some of the rumoured features. Today, the company has released a new software update, which has enabled one important new feature called Sky Eye. The new feature enables iris scanning capabilities to the phone.

The Sky Eye adds the ability to use the distinctive patterns of the iris in your eye to unlock the smartphone. The update weighs only 25.40 MB and before updating your phone, the company recommends cleaning out the cache memory or the feature might not work properly. The OS version is still Android 5.0 Lollipop with Android MiFavor 3.0 user interface, so the update only enables the Sky Eye.
