iOS 7.0.6 lock screen indicators (4 dots) invisible with solid black background
After upgrading to iOS 7.0.6, the four small circles under "Enter Passcode" that provide feedback for a four-digit lock screen code are no longer visible with a solid black background. Call me boring, but I have had a solid black background since my iPhone 3 with no problems until now. Functionally, the four-digit passcode still works; you just do not see any visual feedback as you type.
