ZTE announced an interesting smartphone that belongs to the mid-range back on January. It's called the Blade S6 and while it's design looks similar to some other smartphones, the asking price of around $250 makes it an option worth considering because of the specs integrated in it. The screen measures 5 inches and it has HD resolution and the phone is powered by the Snapdragon 615 processor, which features 64-bit architecture, so it can take advantage of the support of the technology that Android 5.0 brought. The 2 GB of RAM should be enough to make a quite smooth experience while navigating through some apps and there's 16 GB of internal storage which can be expanded. The cameras included are a 13-megapixel one on the back and a 5-megpixel one on the front.
Speaking of which, an update has been found on that phone that make it even more attractive and it involves a new way of unlocking the device using the front facing camera. It's called Sky Eye Security and while no specifics were given as to how it works, it allows users to unlock their phones by capturing their eyes. It seems almost too simple to enable such a feature with just a software update, although it remains to be seen how accurate or secure this new feature will be, as the front facing camera doesn't use one of the highest resolution sensors.
Iris scanning technology seems interesting as its implementation could be rather easy in today's smartphones, and some manufacturers have figured out a way to include it in low-cost devices, although it is not specified what kind of technologies the cameras must have in order to make them secure enough. The update of the Blade S6 is rather light, it only weights 25.4 MB, but ZTE still recommends that users use a WiFi connection and to make sure that the device has more than 30% of battery. Also, users should clear the cache or the update might not install properly, but the install won't affect any of the data stored in it as well as the settings. While it's not unheard of in any respect for OEMs to add in one or two new features with an incremental update, this is an interesting one to introduce.
