I set a lock screen pattern for my device with a 10 minute delay. However, the lock screen is automatically activated as soon as I hit the power button. I notice the description reads "lock screen X Minutes after screen AUTOMATICALLY turns off" so I let the screen turn off itself opposed to hitting the power button, and then it works as its supposed to. Is there a way to bypass that? I would like to have it locked after a certain time of inactivity and be able to power off the screen with the button.
