Feeling a little green (or pink)
Some users report a similar issue with a pink line instead of a green one.
These reports have surfaced across various forums and platforms like Reddit and X, involving multiple Galaxy S23-series phones.
One user on X describes the problem with their Samsung Galaxy S23 Ultra, stating the device had not been damaged before the update.
Android Authority notes that Samsungās free screen replacement offer for the Galaxy S23 series is only valid within three years of purchase. Consequently, those who bought their phone within four months of its 17 February 2023 release may have to cover repair costs themselves.
Previous reports on the green line bug often pointed to overheating as a common factor. Unofficial advice includes updating the device at night and ensuring it is not plugged in during use.
Due to the persistent nature of this display bug, it is recommended to delay installing the One UI 8.5 update on Galaxy phones to avoid potential issues.
Looking forward, One UI 9, based on Android 17, is anticipated to launch with the Galaxy Z Fold 8 and Z Flip 8 series in July.
