• Software inaccuracies (iOS glitches): Some so far known bugs in iOS 18 that cause delay or lack of response to touch.
• Screen-drivers or firmware-sensing errors: The digitizer firmware or display drivers might malfunction after updates.

• Excessive Temperature: It has been felt how the iPhone does not respond when it is very hot especially in India.
• Screen Protector Issues: An uncertified low-quality screen protector interferes with the touch.
• Problems that came after the new iOS update: For example, some iPhone 16 users in iOS 18.2 or 18.3 said that the response to touch becomes irregular after the update.
