Screen lock POL

screenlock POL locks the screen or covers it with a black overlay. Use it when you want the display held, covered, or kept awake. How to use it 1. Open the app. On the home screen, choose one action: • Lock — show the lock screen. • Black screen only — cover the display in black, with no PIN. • Keep-awake lock — lock and keep the display from sleeping. 2. Unlock a normal lock by entering the PIN you set in Settings. You can also tap the corner lock, or drag that lock to the center. 3. Dismiss a black screen with the gesture you chose in Settings: a corner tap, or a drag to the center. 4. Open Settings from the lock control. There you can change the language, set your PIN, read Help, and tap Lock now. The app does not replace the iPhone passcode. It only locks or covers the screen while screenlock POL is open.
