Samsung galaxy s26 ultra hit by mysterious green line issue, owners report
A new and worrying issue has been reported by some SamsungGalaxy S26 Ultra owners - a mysterious green line appearing on their device's display. The problem, characterized by a neon green line running vertically from top to bottom on the left side of the screen, seems to be irreversible and prompts a phone return to Samsung for repair if under warranty.

Users share evidence, but red flags raised over fakes
Several owners have shared images and videos of the alleged issue, with some looking convincing, while others appear suspiciously staged. One video posted by a user on Twitter shows the green line persisting even after opening various apps, while others have only shared photos that some claim are fakes.
A discussion on Reddit points to a popular Brazilian Facebook group dedicated to Galaxy S Ultra phones (S23-S26 models) with green line issues, hinting at a wider problem. However, the authenticity of some reports remains in question.
Samsung has yet to officially comment on the issue, leaving owners in limbo. The Galaxy S26 Ultra is a highly anticipated flagship device, and this unexpected problem may raise concerns about quality control and durability.
