Galaxy S6 edge fingerprint scanner - can't add fingerprint (+1 other problem)

[AC Question]

Hi!
Just recently when I tried to add a new fingerprinted i noticed that it doesn't work anymore. When I choose "add fingerprint" I'm stuck on the screen that shows a drawn phone and hand and that explains how to place your finger. Even when I try to place my finger just as shown on the picture nothing happens, it doesn't go to the next screen to save the fingerprint. I think it's a software issue because i've got other fingerprints saved and they do work when I have to open my phone.
My other problem is related to the camera. When i'm on the camera of the phone and i click on the settings icon, the settings page opens but almost instantly closes and it goes back to the camera. I can't change my settings and that's quite annoying.
I'm under android 5.1.1 with a Samsung Galaxy S6 Edge.
Thank you so much for reading this, I hope you will have answers to my questions ^_^

Try wiping the cache partition: https://support.t-mobile.com/docs/DOC-21095

Thanks for your answer. Yet it didn't work (for both issues :/)

See if it works in Safe Mode: https://support.t-mobile.com/docs/DOC-21007

Didn't work either I'm afraid :/

If it doesn't work in Safe Mode, then I would suspect either a firmware or hardware problem. You could try reinstalling the firmware, using either Samsung Smart Switch or Odin: http://forums.androidcentral.com/am...w-flash-stock-rom-via-odin-new-interface.html

If that doesn't help, then contact Samsung for warranty repair.
