The One UI 8.5 update has added a lot of interesting features to all the eligible devices. But multiple online complaints suggest that it has also introduced the hated green line display issue on some Galaxy S23 series phones. Here's how widespread the issue is and what you should do to ensure that your device doesn't get affected by it.

The green line problem is back for some Galaxy S23 owners


After launching it with the Galaxy S26 lineup, Samsung made the One UI 8.5 update available for its Galaxy S23 series phones last month. Unlike what the company would have expected, reports started surfacing online that Galaxy S23 users are seeing a vertical green line after installing the update. Initially it was believed to be a few isolated cases, but recently plenty of similar reports have been made online.

Samsung's community forum and online forums like Reddit and Threads have a good number of reports with users claiming that their phone started showing the green line just after installing the One UI 8.5 update. The problem isn't exclusive to the vanilla variant; it has been spotted in the Ultra model as well.

It's occurring even on fresh devices




Whenever we hear about a display issue, we assume that it might be stemming from any sort of physical damage or crack on the screen. But interestingly, the current wave of green line issues on the Galaxy S23 series seems to be happening even on devices that don't have any sort of physical damage.

A Galaxy S23 Ultra user posted on X that the device started displaying a vertical green line immediately after installing the latest software update. They further mentioned that this happened even though there wasn't any sign of physical damage on their device.

There are a few reports of users also seeing a pink line. A Reddit user posted that the Galaxy phone started showing a pink line after installing the May security update. A similar complaint was made on the Samsung community forum, with this user also claiming that they experienced this issue even though their S23 Ultra wasn't physically damaged by any means.

What could be causing the green and pink line problem



As of now, there is no official confirmation on what exactly could be the reason here. But overheating during the update process is usually seen as the main culprit in such situations. A user apparently became so cautious of this situation that they updated their device while keeping it on an ice tray.

That definitely seems to be a sarcastic comment and is really a far-fetched approach, but it is generally recommended to keep your phone cool whenever you are updating it. You should make sure that you are not updating it directly in the sunlight or while it is plugged in.

That said, many reputable tipsters, including Tarun Vats, are recommending avoiding installing the update unless absolutely necessary. But if you ask for my advice, I would say I am in a dilemma currently. You see, there's definitely a good number of online reports to prove that this isn't an issue that's occurring only on a few devices.

But it's also hard to ignore comments from users who report that they didn't experience anything like this on their Galaxy S23 series phones and also mentioned that their device became a lot smoother and more responsive after installing the update. So, I would advise holding off from updating the device until there is more clarity on this matter. But still, if you want, you must make sure you're updating it when your device temperature isn't very high and also that it has enough battery and isn't connected to charging.

Do you think the current Galaxy S23 green line reports are being blown out of proportion?

Not a new problem for Samsung


It's definitely not the first time we are hearing about the green line issue on a Samsung phone. We have seen plenty of complaints in the past as well with different devices affected by it. What's even worse is that we have already seen a few reports of it also affecting the recently released Galaxy S26 Ultra.

I really think all the innovative features, like the privacy display, would mean nothing if Samsung can't separate itself from the green line complaints that surface every now and then. It's not that no other brand experiences this problem. There have been reports of the green line problem occurring on iPhone and Pixel devices.

However, I feel that it is quite regularly happening on Samsung phones. That said, if your device is out of warranty, then reports suggest that you might have to pay ₹19,500 (~$206 via direct conversion) to get your phone screen repaired if it is affected by the green line issue.
