Samsung's upcoming Galaxy S5 was long expected to feature an eye scanner for improved security. That feature, however, appears to have been shelved in exchange for a fingerprint scanner - one that could encompass the entire screen according to at least one Samsung insider as reported by iTechAddict.

Apple's Touch ID on the iPhone 5s set the standard for smartphone fingerprint security but that implementation requires a user to place their digit on the Home button for scanning. Samsung's idea, however, would allow users to unlock the phone and possibly authorize purchases by touching anywhere on the screen.

You might not have heard of iTechAddict but they seem to have a pretty solid track record as they correctly pegged the rollout date for Android 4.4 Kit Kat. Furthermore, we've also heard rumblings of a fingerprint reader from the ever-reliable @evleaks and KGI analyst Ming-Chi Kuo so that adds a bit of validity as well.

Galaxy S5 rumors in general have been heating up in recent weeks as we approach the reveal later this month. One of the biggest changes for the S5 could be the shift to a metal chassis, a move that we've been hearing about since at least last summer.

The handset is also expected to carry an ultra-high resolution AMOLED display operating at 2,560 x 1,440, a quad-core Snapgradon chip or octa-core Exynos SoC depending on region, 3GB and up to 128GB of internal storage.

We'll know more come February 24 as Samsung reveals their next flagship in Barcelona.
