Samsung's Galaxy S5 will use its entire screen as one giant fingerprint sensor. At least, that's a new tidbit served up by someone considered a Samsung insider.

Leaking the information to blog site iTechAddict, the "well-placed insider within Samsung India R&D," said that the fingerprint sensor will be the screen itself. Theoretically, that means users would be able to touch anywhere on the display to unlock the phone and gain access to secure apps and content.

How reliable is this intel? iTechAddict said that tips from this insider have been on the money in the past, including news about the Android 4.4 KitKat rollout date for Samsung's Galaxy lineup. Known leaker @evleaks and KGI analyst Ming-Chi Kuo also have hinted at a fingerprint sensor for the S5.

Apple already offers a Touch ID fingerprint sensor on its iPhone 5S but that one can only be triggered by holding down the Home button. Developing a sensor that can encompass the whole screen seems a logical next step, especially if Samsung wants to one-up its arch rival with its next flagship phone.
