we should have iris scanning on the S7

[Habsfan]

impossible since the device doesn't support it. And that's the way tech works. when the s9 gets released I'm sure it will have stuff the S8 doesn't have

[Bhinjan]

s7 doesnot support iris scan. plus i dont thinkit has the hardware for iris scanner so theres no chance that you will get it in later software update.

S7 does not have the IRIS scanner. So the device is not capable of scanning any eyes! haha.

Havafan nailed it. Unsupported and it does not have the physical iris scanner. Btw look at note 8 dual camera. s8 single camera

that's like saying I want fingerprint on my iPhone 4s because 5s has it! More clearly saying , if you don't have the hardware you won't have the feature. Plain and simple.
