It stopped working at the same time so i figured it might not be hsrdware related since they are separate hardware (iris is with front cam and sensors have their own sensory array). Everything under sensors dont give value (when using #0#) and iris just gave an error message (also in #0#). Ive done factory reset with no luck. Im out of warranty by the way since im not on the country of purchase. What would likely be the problem? Should I buy parts and replace them myself? Thanks

I have the same issues too. I think this is the flaw/bug of the samsung S8. It happen sudently the same. Samsung need to pay atention to this and need to fix it.

Try giving your phone an update, If that doesn’t work you may have to get them replaced but may cost a small fortune. Take it into a shop and see if they can figure the problem out if this doesn’t help. Good luck :)

have you try to downgrade the firmware?

I have the same problem with my s8 but my front cam is also not working. On #0# show gray eyes and shuts with error show changed 157 and revision $2 type and front camera failed on #0# also. I tried my camera module to other s8 it works flowsly may be its and hardware issue . Would you like to tell me where is the ic of front camera and iris scanner is placed

I have the same problem but with my iris scanner when I press start for it to scan my front camera doesnt show up at all, the 2 circles for my eyes stays blank and the scanner stays at 0% but my front camera works on my normal camera so I have no idea why I can’t scan my irises. I did the full software update and everything, does anybody know why my camera isnt showing up to scan my eyes?
