- Side Button Shortcuts: Apple allows users to double-press or triple-press the Side button to activate features like Guided Access, Accessibility Shortcut, or Apple Pay. When these shortcuts are enabled, the system may briefly wait for additional button input, which can cause the screen lock to be delayed.
- Accessibility Features: Certain accessibility settings, especially those linked to the Side button, may keep the system active for a moment and lead to a short delay before the iPhone screen turns off.
- Apple Pay Quick Access: The Apple Pay shortcut triggered by double-pressing the Side button may also affect how quickly the screen locks.
- iOS System Glitches: Sometimes, the iPhone delayed screen lock problem can be caused by temporary iOS bugs or system errors. In this situation, using a reliable iOS repair tool can help fix the underlying system issue.
