Key Takeaways
- Some iPhone 18 Pro users are experiencing green patches in photos and videos.
- The issue is more common in dark environments and under warm lighting.
- Apple has not confirmed a fix or acknowledged widespread reports.
Users of the iPhone 18 Pro are reporting strange green patches appearing in photos and videos, particularly in dark environments and under warm lighting conditions.
According to reports, the green patches are more frequently observed when shooting at 2x zoom or higher, and in some cases, they are not visible in the camera preview but appear in the final saved image.
The iPhone 18 Pro introduces a variable aperture on its main camera, which can switch between f/1.48, f/1.8, f/2.8, and f/4.0. Apple states that the f/1.48 setting allows the most light to enter the camera, while f/1.8 provides a balance between low-light performance and depth of field.
Mediastorm, a technology testing firm, conducted tests on the new camera and observed significant lens flare when using the widest f/1.48 aperture. Strong light entering from the side produced large areas of unwanted light in images, while closing the aperture toward f/4 substantially reduced the effect.
However, it is not yet clear whether the green patches reported by users are caused by the variable aperture. Lens flare can have multiple causes, and further testing is needed to determine the exact source of the issue.
Apple has not confirmed any reports of the issue and has not announced a repair program or software update specifically addressing the reported camera behavior.
More testing and an official response from Apple will be needed to establish the cause of the green patches. The issue is not unique to the iPhone 18 Pro, as lens flare is not new to smartphone cameras and can be caused by bright light sources, particularly at night.
Apple’s support has not yet received user reports about the issue, and it is too early to determine whether the problem represents a hardware defect affecting iPhone 18 Pro units generally.
The variable aperture feature of the iPhone 18 Pro gives users greater control over how the camera captures light, but early testing suggests that the widest f/1.48 setting can also produce more noticeable flare in certain scenes.
