I'm having a problem locking my phone without turning of the power. When I push the power button and let go, the screen turns off. I have the fingerprint sensor set to unlock the phone. The problem is when the screen is off and I push the power button, the screen turns back on but it isn't locked. Touching the fingerprint sensor also turns it back on unlocked as it should. When I power off the phone and restart it, I have to use my pattern to unlock the phone. Why can't I lock my phone without shutting off the power. I have the setting to lock the phone with the power button turned on. Using or not using the AOD has no effect.
Please help.

 

Never mind, I figured it out myself.

 

There is an obscure setting under
General - Lock Screen & Security - Secure Lock Settings - Smart Lock(unlock setting) - Then there are 3 choices: On body detection, Trusted Places & Trusted devices. I had forgotten that I had played with these a while ago. I had entered my home address in trusted places and I couldn't lock my phone at home. It took me a while to finally find it.
Thanks for trying.
