Samsung will skip Iris scanner in Galaxy S5

Samsung was working on an Iris scanner, so it was rumored that Galaxy S5 would be the smartphone that will be equipped with it. But looks like Samsung plans are a bit different. Sources from inside the Samsung indicated that S5 would not come with an Iris scanner because its not very stable till now. Samsung may provide the Iris scanner in Galaxy Note 4 or Galaxy S6 when the scanner gets more stable.

Samsung has decided to launch S5 with just a fingerprint scanner. Its not that they couldn't make one but its just because it wasn't very stable. But one thing is confirmed that Samsung will surely provide an Iris scanner in its Galaxy smartphone once the scanner gets stable.
