Several reports surfacing online claim that the iPhone 18 Pro series is experiencing a display problem involving green and pink lines. Social media platforms have been filled with photos and videos showing brand-new iPhones with colored lines running down their displays.
When Apple launched the iPhone 18 Pro series in September, buyers had high expectations for the new devices. However, reports of the iPhone 18 Pro green and pink line issue have raised concerns among some users.
What are the green and pink lines?
The problem appears as a highly saturated vertical line stretching across the OLED display. Some users have reported a thick green line near the left edge of the screen, while others have noticed a narrow pink line running vertically through the display. There have also been reports of red lines appearing on some variants sold in Asian markets.

Standard troubleshooting steps reportedly provide little relief. Users say that changing display settings, restarting the phone, or performing a complete factory reset does not make the lines disappear. In affected devices, the lines reportedly remain permanently visible on the screen.
The exact cause of the iPhone 18 Pro green and pink line issue remains unclear. Similar vertical-line problems on OLED displays can be associated with hardware faults, including damage to individual display lanes or components within the panel.
At the same time, some tech observers have questioned whether every viral post documenting the problem is genuine. In today’s highly monetized social media environment, dramatic hardware-failure videos can quickly attract significant attention. Reddit users have also pointed out that some videos appear to show a physically damaged OLED lane responsible for the green line.
Despite concerns about potentially fabricated claims, some complaints appear to involve genuine hardware failures. In those cases, the underlying cause has not been confirmed. Possible explanations could include manufacturing defects affecting individual units, localized panel failures, or accidental physical damage such as drops or impacts.
Separately, earlier reports suggest that some users are experiencing Face ID lockouts. The iPhone 18 Pro series features a redesigned Face ID system with an infrared camera sensor positioned behind the active display panel. Reports indicate that some users attempting to configure their devices have encountered a “Face ID not available” error.
Apple’s response
Apple has reportedly acknowledged some initial launch-related software problems, including Face ID errors and interface freezing. These issues have been linked to the initial build of iOS 27. The company is reportedly preparing a software update aimed at addressing these software-related problems.
However, Apple has not publicly acknowledged the iPhone 18 Pro green and pink line issue. Reports have suggested that the display problem may involve a hardware failure affecting the LTPO+ OLED panel, though the precise cause has not been officially confirmed.
Some users who took affected devices to Apple Store locations have reportedly received replacements under standard warranty terms. That suggests individual cases are being assessed based on the condition of the phone and whether the problem qualifies as a manufacturing defect.
Owners experiencing the iPhone 18 Pro green and pink line issue should document the problem with photos or videos and contact Apple or an Apple Authorized Service Provider. Apple’s limited warranty generally covers manufacturing defects for one year but does not cover accidental damage. Each device may therefore require inspection before Apple determines whether it qualifies for a free repair or replacement.
