You will not upgrade your phone software after watching this video: Green line ghost live

The Green Line issue is a weird problem for AMOLED display phones nowadays. Most of the complaints suggest the green line appears shortly after installation of a phone software update, and an incident has recently been caught on live camera.

Recently, a Reddit user posted a video on the platform, showcasing his phone developing a Green Line on display during software update installation. The affected handset was an S21 FE, which is widely accused of having the OLED defect.

The user is alleged to have kept his phone stuck on an old firmware following the reports of a green line problem. The said software is One UI 6.1, which was released in April 2024 and caused OLED display defects on many Samsung models.

The Redditor claims that he has kept the update install reserved to avoid a potential green line nightmare. The update notification kept popping up daily, but the user managed to spend a whole year (April 2024 to April 2025) avoiding installation.

However, the nightmare came true, that too on live camera, when he decided to install the update. The procedure reached 60% without any defect, but shortly after, the screen spotted a developing thin vertical green line.

As the update installation progressed, the vertical line gradually thickened. The whole incident was being recorded on camera, and an image shared by the user later showcases the green line clearly visible, like we’ve seen on many models.

The Redditor has approached Samsung Support to get the display replaced, however, the service center didn’t offer the same. At the end, the user ended up getting a repair quotation of INR 17000, which is more than half of the device’s current price.

Samsung phones come with a 1-year warranty, covering your phone from any manufacturing defect. However, the green line problem usually occurs on devices older than two years, leading the user to face an unnecessary repair burden.

Well, Samsung offers free screen replacement if proper communication is followed. Meanwhile, many smartphone users would now think many times before hitting the install button, as it could install a green line [feature?] along.
