When I first got my Droid Bionic, if I pressed the power button on the top it would lock the screen; pressing it again would display the keyguard, requiring me to slide to unlock. I had it configured so that if I pressed the power button in less than 5 minutes from the time the screen went off, I got the keygoard and then was able to use my phone. If I pressed the power button after 5 minutes past when the screen turned off, I had to enter my PIN.
On my new Samsung Galaxy SIII, the behavior is not the same. It's acting like my Bionic did for a short period, which was resolved by updating the Bionic to Android v1.4.2: If I press the power button less than 5 minutes after the screen turns off, then I am right into the phone, with no keyguard and susceptible to pocket dialing or deleting.
The behavior I want is:
- Power button turns the screen off
- If the screen is off for less than 5 minutes, power button activates the "swipe to unlock" screen
- If the screen is off for more than 5 minutes, power button requires a PIN to access the phone
- If the screen is off, something should be required to get back into the phone, either "swipe to unlock" or a PIN. I should never be able to get back to the last app/homescreen without doing one or the other (or both) to prevent pocket dials or accidental UI actions.
Settings I currently have set under Settings > Lock Screen:
- Screen Lock: Secured with PIN
- With Swipe Lock: Enabled
- Lock Automatically: 5 Minutes
- Lock instantly with power key: Off (On requires PIN immediately after power key. I want the swipe, and PIN after 5 minutes)
How can I restore the functionality where the keyguard (swipe to unlock) activates instantly but the PIN lock activates only after 5 minutes?
