Three horizontal lines appear on iPhone 18 Pro Max screen in 4K videos

Hello.On my iPhone 18 Pro Max, three horizontal lines appear across the entire screen in 4K videos—both in new recordings and in videos from other iPhones saved in the gallery; there are quite a few of them. This doesn't happen with photos, but the lines show up when I send these videos to others. The issue only occurs in 4K quality; it isn't present in older 1080p videos or new 1080p recordings. What is this? Should I wait for an update, or is it a defect with the 4K lens?

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.

When you encounter issues with your Apple devices, the Genius Bar at Apple Retail Stores is the go-to place for expert assistance. The Genius Bar is staffed by knowledgeable Apple employees, often referred to as "Geniuses," who can diagnose and resolve a wide range of hardware and software-related problems. To ensure personalized attention and a convenient visit, Apple provides the option to schedule a Genius Bar Reservation.

Take your device to an Apple Retail Store or Apple Authorized Service Provider, or contact Apple Support:

  1. If you prefer face-to-face assistance, you can visit an Apple Retail Store. Apple Retail Stores are designed to provide a hands-on experience with Apple products and offer support services. You can speak with Apple specialists, known as "Creative Pros" in some locations, who can assist you with product-related inquiries or minor troubleshooting.
  2. In addition to Apple Retail Stores, there are Apple Authorized Service Providers (AASPs) that are authorized to perform repairs on Apple products. AASPs are independent businesses certified by Apple to offer service and repairs for various Apple devices.

Apple offers various channels for support, including phone support, live chat, and email. The official Apple Support website provides information on how to reach out to Apple for assistance.


Finally, you can also start a repair log or track the status of existing repair --> Apple Repair and Repair Status Check - Official Apple Support
