Grid line appears in Video Gallery on iphone 17 iOS 27.0.1

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.
3. If visiting a physical location is not possible or convenient, you can seek support by contacting Apple Support. 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

In summary, Apple provides customers with a range of support options, including the Genius Bar Reservation system, visits to Apple Retail Stores or Authorized Service Providers, and various channels to contact Apple Support for assistance with their products. These services aim to ensure that Apple users receive the necessary help and support whenever they encounter issues with their devices.

Open the Photos app on your iPhone and check whether the gridlines are visible when you view the image or video. You may be using a third-party application to view the media, and the gridlines could be generated by that application rather than being part of the original image or video.

However, if the gridlines remain visible when you open the same image or video in the Photos app, particularly after it has been saved using a third-party application, it is possible that the gridlines have been embedded in the media itself during processing or editing. In that case, they are no longer merely an overlay displayed by the viewing application.

Could you please clarify the following?

1. Are the gridlines visible in all photos and videos taken with your iPhone, or only in specific ones?
2. Do the gridlines appear when you view the original photos directly in the Photos app, without using any third-party application?
3. Do the gridlines appear only in photos or videos that have been downloaded, imported, or saved from a third-party application?

These details will help determine whether the issue originates from the Camera settings, the viewing application, or the media itself.
