fingerprint sensor on S6 edge

[sophiegriff]

I have had my Edge for 6 months. I have scanned in my finger prints multiple times in different positions stored at the same time and STILL the thing only works 1 out of 10 times. Is this a know malfunction or is my phone broken. i have gone back to pin # because using back up password is just to long. This issue does suck because the fingerprint and samsung pay were the 2 reasons I gave up my S5 and I can use nether one. I have an unlocked S6 edge 925F Euro version and no samsung pay yet.
I do have Square trade warranty and if Its fixable I will send to them.
