Burnt screen connecting ribbon caused from overheating. Though newer models are less likely to see it. It is very common from s20 to s22. It's not just Samsung that has the issue. In some countries you get a free screen repair. I guess they haven't mastered the OLED and AMOLED screen tech on phones fully. Just avoid overheating your phone for too long and it will be fine.

AMOLED shiiiiiiiiiiiiiiiiiiiiiiiiiii shiiiiiiiiiiiiiiiiiiiiiiiiiiit

This still remains the only advantage of IPS LCD screens over AMOLED screens



Well, you get to enjoy the cozy beautiful screen and lush displays that OLED and AMOLED screens have to offer then boom

Your screen is Toast!

ENJOY

Btw
Some people claim that those companies intentionally use these screens so that people would have to change screens or buy another device

That's why the Green screen thingy tends to start after about 1year
Re: Why Do Samsung Phones Have Green Line On Thier Screen? by njokuuche77(m):
The green line on Samsung phones is usually a display defect linked to heat and stress on the AMOLED screen and flex cable. Too much of heat can fry the flex cable.
Many users notice it after updates or prolonged heat exposure. The permanent fix is screen replacement, but prevention helps alot.

Like what i do is always updating in a cool environment (fan/AC) to avoid overheating, since excess heat is the main trigger. Then try to use strong wifi to do the update.

My s10+ is currently like this, same as my s20+5g. I have decided to keep using them like that till it goes blind completely. Screen replacement cost, it is around 80% price of a new one phone.

You were probably not using it heavily


Like for 3 to 4 to 5days in a row without switching off the device for a while

Story story!

My s20+ 5g came in brand new, it started having lines after a year of usage
Re: Why Do Samsung Phones Have Green Line On Thier Screen? by NobleSeed(m): 1:24pm On Oct 02, 2025
the line usually displayed on the Samsung screen most times are from the S_series and the fold series, but not commonly on the note series.
Samsung originally from the UK and the US hardly have these lines cause the screen are most times of high quality.
The ones which mostly have these issues are the ones from China which some dealers sell as UK and brand new.

If it's your dream phone, start resleeping

You would get a better dream later

I've been using my Samsung A21s for 4 years now and I have never experienced this. I always use screen guard and leather back cover

huh

Practically most of all phones screen has green lines when they get spoilt, it's the materials used to produce the screen that made them like that, this is not for only Samsung, but for all phones

It wasn’t just Samsung—my Tecno Spark 40 Pro Plus also gave me issues. I was playing Efootball 2026 when suddenly the buttons froze. I quickly exited the game, but a few minutes later, the screen started flickering—going off and on. I could only hear the audio, but nothing was displaying. I rushed back to the store where I bought it, and they directed me to Carlcare. Surprisingly, as soon as I stepped into the building, the phone returned to normal. They reassured me that if it happens again, I can bring it back for a replacement, as long as no technician has tampered with it. Since then, I’ve stopped playing games. After seeing this post, I realized the issue was most likely caused by overheating.

You didn't include refrigerator.
I presume users in russia would not be having such issues..since the country na confirm refrigerator on its own.

You would see those lines clearly.


It's Overheating that tends to cause those lines on the screen

Oh!

And Samsung Galaxy A21 is not AMOLED, it's IPS LCD
Re: Why Do Samsung Phones Have Green Line On Thier Screen? by Antoeni(m): 1:29pm On Oct 02, 2025
Lines on a Samsung screen are typically caused by hardware issues like a loose display connector, physical impact from drops, or water damage, though software glitches or overheating can also be factors
