Some iPhone 18 Pro owners are reporting display problems involving bright vertical lines that remain visible across the screen, prompting questions about whether certain devices are experiencing hardware failures.

Photos and videos circulating on social media show what users describe as highly saturated green and pink lines extending vertically across the OLED display. Some reports describe a thick green line near the edge of the screen, while others show a narrower pink line running through the display.

Additional reports from some Asian markets have described red lines appearing on certain devices.

Users who claim to have encountered the problem say conventional troubleshooting has not resolved it. Restarting the phone, changing display settings, and performing a factory reset have reportedly failed to remove the lines on affected devices.

The cause remains unclear. Vertical lines on OLED displays can result from hardware problems involving the panel or individual display components, but there is currently no confirmed explanation for the reports involving the iPhone 18 Pro.

The authenticity and circumstances of individual social media posts also remain difficult to establish. Some online users have questioned whether every viral image or video represents a genuine manufacturing problem, while others have suggested that some examples could involve physical damage to the display.

That leaves several possible explanations for the reports, including isolated manufacturing defects, individual OLED panel failures, or damage caused by drops and other impacts. No broader cause has been officially established.

The display reports are separate from other launch-related problems that have been associated with the iPhone 18 Pro series. Some users have reportedly encountered Face ID problems, including messages indicating that the feature is unavailable.

The latest iPhone models use a redesigned Face ID system with an infrared camera positioned behind the active display panel. Apple has also reportedly been preparing software fixes for certain early issues involving Face ID and interface performance.

Apple has not publicly confirmed that the reported green, pink, or red lines represent a widespread defect with the iPhone 18 Pro display.

Some customers who have brought affected phones to Apple retail locations have reportedly received replacement devices under warranty. Whether a particular device qualifies for a free repair or replacement can depend on Apple's inspection and determination of whether the problem resulted from a manufacturing defect or accidental damage.

Owners experiencing persistent display lines can document the problem with photos or video before contacting Apple or an authorized service provider. The device can then be inspected to determine the cause and whether it is covered by the applicable warranty.
