Reports indicate that a number of Samsung Galaxy S23 owners are experiencing permanent green and pink lines appearing on their displays immediately after installing the recent One UI 8.5 update.

• The issue is believed to be exacerbated by thermal stress on the device during the update process, potentially highlighting an underlying hardware vulnerability.
• Affected users are advised to contact Samsung Customer Support for potential out-of-warranty assistance, though a previous free replacement program expired on December 25, 2025.
• This display defect is not exclusive to Samsung, with other smartphone brands also facing similar longevity challenges with OLED panels.
