Low Power Mode can also affect the auto-lock feature:

Customizing Lock Screen Issues

If you're having trouble customizing your lock screen, here are some tips:

Unlock Your iPhone First

To customize the lock screen, ensure your iPhone is unlocked:

  1. Unlock Your iPhone: Make sure your iPhone is unlocked before attempting to customize the lock screen.
  2. Access Lock Screen Settings: You can access the lock screen customization options from Settings > Wallpaper or by long-pressing on the lock screen and entering your passcode if prompted.

Workaround for Face ID Issues

If Face ID is not working, you might encounter difficulties editing the lock screen:

  1. Swipe Up and Enter Passcode: Swipe up and enter your passcode to unlock the phone.
  2. Swipe Down to Access Lock Screen: Swipe down from the top to bring the lock screen back, then try editing it.
  3. Alternative Method: Go to Settings > Wallpaper to customize the lock screen.

Securing Your iPhone from Unauthorized Changes

To prevent unauthorized changes to your account settings, you can use Screen Time:

Enable Screen Time and Set Passcode

  1. Open Settings: Go to the Settings app.
  2. Screen Time: Navigate to Screen Time and turn it on.
  3. Set Screen Time Passcode: Set a passcode for Screen Time.
  4. Content and Privacy Restrictions: Enable Content and Privacy Restrictions.
  5. Restrict Changes: Under Allow Changes, set Passcode Changes and Account Changes to Don't Allow.

This setup ensures that even if someone knows your device passcode, they cannot change your Apple ID or iCloud account password without the separate Screen Time passcode.
