Samsung Green Line issue


Samsung Galaxy smartphones have long been using AMOLED screens, especially the flagship phones, In the past five years, this technology has also been utilized in mid-range as well as some budget-friendly devices, but a display-related issue, known as Green Line, still appears to this date.

AMOLED panels have rapidly evolved in the mobile industry, but the green line issue has remained the same since its first appearance. To be clear, the majority of the phones are working in good shape, but this problem has become quite obvious and widely reported online. So, let’s explore this entire issue in detail.

What’s the Green line issue​

It causes the disturbance in screen pixels and forms a line (or lines) that overlays the on-screen content. In most cases, these lines are spotted vertically, but in a few rare cases, some users report horizontal and, sometimes, in pink and white colors.

The majority of such cases are reported in India, but it’s also spread in other parts of the world. You can find user reports with queries “Samsung green line” on Samsung forums, X (formerly Twitter), and Reddit.

Origin of the green line issue​

There’s no clear explanation behind its origin, but it’s very likely a hardware or software-related problem, including the following.

Display Panel – Such phones with issues may have a faulty display or degraded longevity over time, leading to pixel disturbance, which could turn permanent.

Software update – Many users reported that the green line appeared during or after an update installation. Some of these mentioned One UI 7, the latest major OS update. Which raises the point that the issue may be caused by software and hardware incompatibility.

Temperature: Using a phone in high temperatures could lead to a display-specific problem. Scenarios such as using the phone while charging, long sessions of high-performance games and apps, video recording, and software update pressurize the processing unit and generate heat inside the device. This heat, when it’s not dissipated through the internal thermal system, reflects through the screen. Though the displays are designed to endure high temperatures, this logic cannot be applied to any defective or degraded panel.

Physical damage – Last but not least, dropping the device, applying unnecessary force, or long exposure to direct sunlight are some of the last reasons that could lead to the green line issue. However, these are accidental instead of intentional.

Samsung phones affected by the green line issue​

This issue has been experienced across the flagship, foldable, as well as mid-range devices featuring AMOLED displays. These are showing single, multiple, different colored, and horizontal lines. Here are the flagship phones:

  • Galaxy Note 20 series
  • Galaxy S20 series
  • Galaxy S21 series
  • Galaxy S22 Series
  • Galaxy S23 series
  • Galaxy S24 series
  • Galaxy Z Fold series
  • Galaxy Z Flip series
  • Galaxy A-series
  • Galaxy M-series
A few people also reported this issue for the S25 series, but the number is pretty negligible.

Official Response​

Samsung has acknowledged the issue and is providing a free one-time screen replacement program in India, which is likely to be similar in other countries. This activity has certain conditions that the affected device must meet, including a physical device inspection.

On the downside, this program allegedly excluded the S23, S24, and S25 series. Long-term customers, who are using their phones after the warranty, are also not getting replacements.

According to the recent information, Samsung has extended the one-time replacement program to September 2025 in India. You can learn more about the eligibility by visiting your nearest Samsung store or service center.

What’s the solution?​

This problem cannot be resolved with the air (OTA) update, any specific software patch, or trick. So, getting a display replacement is the only solution. Consider yourself lucky if this problem gets resolved automatically.

Is this a Samsung-only problem?​

It could be found across all AMOLED display devices from other phone makers: OnePlus, Vivo, Xiaomi, and more. However, Samsung users reported more of such issues.

Here are a few tips​

Here are a few tips to manage your phone.
  • Beware of the phone’s temperature and ensure that it doesn’t remain hot for longer durations. If so, visit the service center.
  • Don’t expose the phone too much to direct sunlight, which could cause thermal damage to the display.
  • Similarly, try updating your phone overnight with the schedule feature when the phone is not in use.
  • Don’t use the phone while charging

Our take​

This green line issue is not new, and Samsung smartphone users are continuously are still facing this issue in 2025. Although the number might not be big but this has become a common problem in different devices and it’s not going away.

Samsung should’ve created a task force to look into this matter and implement a fix, so it won’t appear in future releases and stop haunting users.

Can rule out high temperature, at least for china flagships.

Below video did 1000 charging cycles with phones screen set to 100% lit all time, max fast charging, max discharge using software to run the cpu gpu at max power to finish the test in shortest time and exposed to high ambient temperature during china summer. Phones were subjected to very high temperature all the time for 129 days to 170 days

All only various degree of screen burn.

this doesn't prove anything
these models never had the green line issue that pop out for no reason

it was always the models that were released during covid era that somehow has this problem which suggests its a design issue

also most people have the green line appear after the phone gets hot. like the first article said, playing games while charging is an easy way to replicate, esp if u r using super fast charging

The green lines are killing their sales. They need to keep their act altogether.

Before covid already had green lines. S8 was widespread badly affected with green lines, whole screen green tint. Before that some report of s6 s7 also had green line.

After covid also had green lines. Many online phone review news website reported many S24 was affected by green line last year.

nothing changed and confirm not caused by covid era.

The video i posted above discharged battery as fast as possible with software running the cpu/gpu at max power will heat up phone hotter than fast charging, os ota update, play game.

Samsung fast charge is a joke compared to the china brands flagship phones.

Won't buy Samsung..all the Samsung we have had this issue..only 1 was replaced under warranty..all are flagship phone..all happened after update. One have green line after less than 1 yr of use..

Never have issue with Sony...recently someone in office asked for S25 ultra...let see if the green line pop up. Guy was told if any issue with the phone and not covered by warranty, he will have to get his own phone.
