If you are seeing a vertical green line on your Samsung phone screen the pixels below the green line have burned completely and can’t be recovered with any software update.

Causes of Samsung Green Line

The dead pixels of an AMOLED display causes Samsung green line to appear on a mobile screen. There could be various reasons for Samsung green line on screen. Some of the most common reasons that can cause vertical Green lines on Samsung phone’s screen.

Loose display connections.
Overheating of display when used for long time in sunlight or hot weather conditions.
Uncontrolled voltage supply to few pixels in the display due to faulty display connection.
Samsung phone screen damage due to fall from a certain height.
Excessive pressure on the screen in the pocket or due to other things.
Wrong configuration of application or faulty applications.
Problem in hardware and software optimization.
Display damage due to liquid or water.

Generally, a vertical green line appears on a Samsung phone screen after the fall of your device from a certain height, excessive pressure on the screen, or damage to the screen due to any liquid. When your smartphone falls from a certain height, it causes the screen connection to lose and loose display connections can send unmanaged or faulty voltage to a certain area of your screen.

Faulty or unregulated voltage destroys the pixels on your smartphone screens and dead pixels start showing bright green. Here you can also see an example of a green line that appears after the damage of pixels on the screen.

Samsung green line on screen after update

We have also heard from many smartphone users including Samsung, OnePlus, Vivo, and others that they are facing vertical green line on screen issues after a software update. And some people are also saying that smartphone brands are doing it intentionally after the end of their Warranty so that their users can buy new smartphones.

But we don’t think that any smartphone brand will do this because it directly impacts the brand value of the smartphone company so this could be just a rumor. We don’t know the real truth but in our opinion, it may be just a myth.

However, we never deny that many smartphone users are facing green line issues after the software update. This could happen after an update as there could occur an issue while updating the software of your device which can send unregulated voltage to your smartphone screen for a while and that can cause green lines to appear on your phone screen.

You should always use a screen guard on your smartphone screen. If you have applied a screen guard on your smartphone screen but it has broken then you should consider replacing it as soon as possible.

We also recommend using a good quality back cover on your smartphone as good quality back covers that cover all edges of your smartphone completely can provide your smartphone even better protection than a screen guard.

Always take care of your smartphone and never let it fall from a certain height that can cause physical damage including internal and external damage to your smartphone.

You can use that video as proof to produce in front of Samsung if they deny the free screen replacement even after the end of your phone warranty.
