Context: The Samsung Galaxy S23 series, more than three years old, is experiencing a new display bug where users are reporting neon green or pink vertical lines cutting across their screens after updating to One UI 8.5. This issue is affecting some users of the base S23 and S23 Ultra models, with reports emerging from various platforms including Reddit, Samsung's community forum, and X. The problem may be caused by thermal stress during the installation of the update.
Key Facts
- A growing number of Galaxy S23 users are reporting seeing neon green or pink vertical lines cutting across their otherwise pristine display after updating to One UI 8.5.
- The issue is affecting the base S23 and the S23 Ultra models, with no reports found for the S23+ model, and is not a universal problem due to varying thermal stress effects on different units.
- According to user reports on platforms like Reddit, Samsung's community forum, and X, the recently-released One UI 8.5 update is the culprit, potentially causing display connectors to fail due to thermal stress during installation.
- Samsung had previously offered free display replacements for similar issues with S23 devices, with a cutoff date of 2025, but it is unclear if a similar program will be launched for those affected this time around.
- Users with Galaxy S23 series devices that haven't been updated to One UI 8.5 yet are advised to delay the update until Samsung acknowledges the issue and shares a solution.
