In the last few years, many users of Samsung smartphones with AMOLED displays have reported that their phone’s screen develops a permanent green line (or sometimes multiple green lines) as the phone ages or while installing a software update. However, we never got to see the green line appear in real time. Well, that has finally changed.

On Reddit, a user posted a video of their Galaxy S21 FE updating to One UI 6.1 (Android 14). When the installation was about 60% complete, a green line appeared on the left-hand side of the display. From what we can gather, this is the first video to show the line appearing on a Samsung phone’s display in real time.

The user, who seems to be from India, says that they read reports about a green line appearing on the screen when updating the Galaxy S21 FE to One UI 6.1, and as a result, they ignored the update for a long time. However, they finally decided to install it to get rid of the constant update reminders.

The user also decided to record a video of the installation process to make sure they will have proof that the green line appeared on its own and not because the device was mishandled or damaged in any way, which would allow them to get the screen repaired at a Samsung service center without needing to pay repair charges.

Thankfully, Samsung acknowledged the issue long ago and is still replacing affected display panels for free. In India, the brand recently extended the period for people to avail the replacement program till September 2025.
