Has anyone experienced two white horizontal lines in the Camera app when zooming quickly on iPhone 16 Pro Max?

I’m using an iPhone 16 Pro Max running iOS 27.0.1.


When I set Display Zoom to “Larger Text” and zoom rapidly in Video mode, two horizontal white lines appear across the Camera interface. They remain visible until I close and reopen the Camera app, but they do not appear in the recorded video.


After switching Display Zoom back to “Default,” I tested the same operation multiple times and could no longer reproduce the issue.


Has anyone else experienced this behavior? Does anyone know what might be causing it?


I hope Apple can investigate and fix this issue as soon as possible, as it is very annoying and disruptive when recording videos.

Expressing or conveying visual experiences effectively through these forums may be challenging. The underlying visual issue on your iPhone cannot be accurately diagnosed online. Factors such as your iPhone's specific settings, visual defects, and potential hardware problems cannot be assessed through this method. For more personalized and in-depth assistance, I recommend securing a Genius Bar Reservation and exploring the various support options provided by Apple.

You may be able to create a shortcut that disables Display Zoom when the Camera app is opened. This will at least minimize the hassle of restarting the app.

Welcome and thank you for reaching out. 🤗


There appears to be a problem with the camera and/or related sensors. Only a certified Apple technician can determine the cause and offer a complete solution.


Therefore, I recommend service.
