Part 2: Why My iPhone 12/13 Touch Screen Not Working

1. Dirt on your hand or the screen

The dirt on your hand or the screen can cause the touch screen to stop working because the dirt can act as a barrier between your finger and the screen, making it difficult for the touch screen to sense your finger.

2. Interference from screen protectors or accessories like Lightning cable

One common reason for an iPhone touch screen not working is interference from accessories like screen protectors or Lightning cables. A poorly fitted screen protector or cable placed too close to the display can prevent the screen from properly detecting touch.

Issues with the operating system, hardware, or software can all lead to an iPhone screen not responding to touch, causing problems like the iPhone 12 touch screen not working can't unlock scenario many users face.

4. Out-of-date iOS Version
