    I have had my S7 5 months, and awoke this morning to a black screen asking for my pattern to unlock the phone. Its not giving me the option to use my thumbprint. Problem is I have only used my thumbprint for so long that I don't remember what the pattern is! Why wont it let me use my Thumb? This has never happened before. I have restarted the phone but it just does the same thing.

    Welcome to Android Central! The phone will still ask you periodically for your backup password/PIN/pattern. It's actually spelled out in a Google support page:

    "For security, you'll need to use your backup PIN, pattern, or password:
    • When your fingerprint isn't recognized after a few tries
    • After restarting (rebooting) your device
    • After switching to a different user on the device
    • After more than 48 hours have passed since you last unlocked using your backup method"
