Samsung Fold 8 Ultra Develops Plus Shaped Display Line Without Damage

I purchased my Samsung Fold 8 Ultra approximately 1.5 months ago. Despite the fact that the factory-installed screen protector is still on the device and it has never been subjected to any impact, drop, pressure, or liquid exposure, a clearly visible LED line in the shape of a “+” appeared in the folding area of the open screen approximately 15 days ago. This issue significantly distorts the display, especially when using the large screen, and prevents me from using the device properly. The attached photo and video clearly show the problem.
For a brand that claims to be a world leader in foldable displays, a defect appearing on its flagship device is certainly not a cosmetic issue. It is a clearly visible electronic manufacturing defect that can be noticed immediately when you hold the phone. Despite this, suggesting that the device should be subjected to a detailed inspection and potentially repaired is, at the very least, an unfair approach toward the consumer. Determining what caused a manufacturing defect that is this clearly visible is the responsibility of the brand and its authorized service centers, not mine. I am a consumer who expects a product to be delivered ready for use in flawless and problem-free condition.
After the problem appeared, I took the device to the place where I purchased it twice and asked them to inspect the screen. I was told that the device needed to be sent to a service center, that approximately one month would be required for inspection, and that the best-case scenario would be a screen replacement. Since I do not consider it acceptable to have the screen replaced and be left without my device for such a long period due to a problem that appeared on its own after such a short time, especially for a product in this price range and category, I refused the screen replacement offer.
This entire process gives the impression that an international brand does not treat its consumers in Türkiye with the same level of care it would provide to American or European consumers. I do not accept Turkish users being treated as second-class customers or being forced to deal with such difficulties even when faced with such an obvious manufacturing defect.
Since only a very short time has passed since I purchased the product, I request that the clearly visible “+”-shaped lines that appeared in the folding area without any user error be evaluated as a manufacturing defect, that a permanent solution be provided under warranty within a reasonable period of time, and, if possible, that the device be replaced with a new, fully functional one. I also request that my inconvenience be resolved as soon as possible.
