Samsung Galaxy S5 to feature iris scanner?

Samsung is rumored to unveil its first QHD device with a 2560 X 1440 resolution at Mobile World Congress in February 2014, according to ZDNet Korea.

The report didn't specifically label this QHD device as the Galaxy S5, but it's unlikely this screen would make its way onto something other than Samsung's next flagship phone.

According to sources, Samsung's Ultra HD-displayed phone will also feature an iris verification system that scans user's eyes as a security measure. The pairing of the eye scanner and the Ultra HD screen strongly suggests the phone in question is the long-rumored S5.

With months of speculation under its belt, the next Galaxy is shaping up to be one of the most intriguing handsets we've heard about in some time.

Aside from its Ultra HD screen, the Samsung Galaxy S5 is believed to come packing a 2.5GHz processor that's also the first 64-bit part for an Android smartphone. In another first, the 5.5-inch device has 4GB of RAM, the most yet seen in a mobile device.
