Black lines appear on iPhone 18 Pro screen when taking photos

Looking at your screenshot, I notice that the black lines are visible in the camera preview. However, the thumbnail in the bottom-left corner, which displays the most recently captured photo, appears to be free of these lines.

This suggests that the issue may not be consistently affecting the photos being captured. Could you please check whether these black lines are also present when you open the captured photos in the Photos app and view them at full resolution?

If the lines are visible only in the live camera preview but not in the captured photos, the issue may be related to the camera preview or display rather than the actual image capture.

It would be helpful to establish whether the lines are present in the saved photographs before concluding that there is a problem with the camera hardware.

This could be an artifact of LED lighting. LED lights running on AC current cycle off and on 60 times a second in the US. and 50 times in most of the rest of the world and it can cause issues like this.

Go outside and take some photos in sunlight. If the lines don't appear, you know it's the LED lights causing it.

Have you tried to force restart it to see if the issues persist?

1. Press and quickly release the volume up button (on iPhone Duo, the volume button nearest the side button).
2. Press and quickly release the volume down button (on iPhone Duo, the other volume button).
3. Press and hold the side button.
4. When the Apple logo appears, release the side button.

It’s actually doing it on the photo itself too , but only sometimes so I don’t understand what is happening

The lines get wider once the brightness is adjusted to darker
