iPhone 7 plus keep asking to input password

[armadilloshield]

Just happen this morning, almost every minutes asking me to input password or touch ID to verify. Even while typing WA msg halfway, screen just gone blank, password screen popup.
So far, not update anything, still with iOS 11.1.2.
Anyone encounter the same issues?
Thank you for your feedback.

Already tried, restart couple of time, it doesn't help.
Last try, reset all settings.
Now seems working fine, not sure what exactly happen.
