    I'm trying to set it up to use fingerprint to unlock my edge phone as I did with my GS6 Edge. I put in my fingerprint and setup the backup pin, but when I turn the phone on and place my fingerprint on the home button it asks for my backup pin. I dont want to have to use my fingerprint then enter a pin.
    Any ideas whats going on?

    Probably a no brainer, but do you have your Screen lock type set to Fingerprints? It's in the Settings>Quick Settings>Lock screen & security

    Yes it's set correctly. I can use the finger print to unlock but it then asks for my pin as well.

    Ok so I redid the settings and same thing. What's interesting though is it worked fine a few times then back to the same issue.

    Answer:
    1. Do not confuse using Encryption & Fingerprint... as opposed to just Fingerprint. Encryption will force use of password EVERY power-up, but NOT for just Re-start or unlock.
    You fail to mention if Encryption selected.

    2. If happening WITHOUT encryption, and JUST on UNLOCKING:
    - I would do the FACTORY DATA RESET and start over.
    - ALSO KEEP IN MIND: There ARE system updates that DO NOT get applied to your Fon for several hours after initial registration with your Carrier..
    - You may just need to wait for those updates.. a bit.

    2. SET UP the FINGERPRINT feature BEFORE setting any other passwords.

    try these..

    I actually figured out the problem fooling around with some things. I always used the screen off and lock app on my other phones. I guess it's not fully compatible with Marshmallow yet.
    If I hit the screen off app button then it will say swipe to unlock when I turn the screen on and then ask for my backup pin even though fingerprints is selected.
    If I use the phones off/on button then no issues at all. I removed the app and all is good.

    I already fixed and and explained how. See my above post. It was just an app I was using that was causing the issue.
