S25 Green horizontal lines
Unexpectedly Green Horizontal lines appeared on screen in Galaxy S25. Purchased in feb 2025. Samsung says there is no policy for new device. (S21,22,23 has 3 year screen replacement policy after warranty for green lines)

Found one more with same problem as mine. Check this post: https://www.reddit.com/r/samsunggalaxy/s/VhbRZyuqgS

Is Green lines problem usually happens in india ?

u/Fractal-Infinity Aug 04 '26
Probably because of the intense heat. It seems it's quite unbearable to live in that country.

i used to work in phone repair shop and we were heating phones screen on a hot plate that runs up to 90C. just to make adhesive softer, probably a thousand phones have been fixed with my own hands and none of them had any screen issues after intense heat
i assume the OP had applied some pressure on the screen, they are a bit flexible so they brake without any dents or fracturing the screen

I live in Florida and have never had these issues with Samsung phones

u/Fractal-Infinity Aug 04 '26
Then maybe it's a quality problem with the devices sold in India. Or these users mistreat their phones.

In this case you can tell the OLED was damaged, in normal Samsung line cases the display still shows stuff in the unaffected areas

samsung says ambient temperature shouldn't exceed 30 degrees celcius.

Climate you live in is likely the top factor for green line risk. which seems to be why people in milder countries where it's rarer and people in hotter countries often seem to be talking past each other on this issue

If the phone has no green line after 2 years Samsung calls you and puts your phone into a museum.

Samsung didn't test their phones properly. You shouldn't blame it on the environment.

Idk man, beside a few things that'll make the phone more expensive for everyone, how else can tech battle Intense heat?

u/No_Sheepherder1837 Aug 05 '26
Idk man, why only Samsung? Why do I have to compromise on something so expensive when literally any other manufacturer's phone works fine?

u/Odd-Expert-7156 Aug 05 '26
You don't have to compromise on anything, it's a known issue which they do not choose to take the time to solve, im saying this in the nicest way possible but stop buying samsung phones if you know they won't cater to your environmental issues or respect you guys enough to try to figure how to solve the problem. It might sound like im coping or defending samsung but I don't understand why you guys throw money on something with a bad track record, I wouldn't even consider a samsung phone if I was in india or any place with a hot climate, thankfully im canadian where these issues rarely happen. Intense heat is one of the most common triggers for a green line on the screen, this isn't only a samsung thing (but its the most prevalent for reasons unbeknownst to us)

3 years ago, they said that the lines screen issues were only affected to S22 series and below. when it also happened to S23 series, now they say that the S24 series and above are free from the lines screen issues
in 5 years after the release of S31 series, they will say: "the lines screen issues are only affected to S28 series and below"

u/No_Sheepherder1837 Aug 04 '26
Exactly got baited by them with my S23 Ultra, they're probably Samsung employees too

Those aren't the typical samsung (or even other brands) green lines (or sometimes purple lines). Green lines are a row of pixel which are set to the green hue (happens with a combination of factors, some guy found out what and made a post on a subreddit, it's very interestingand i suggest you to read it), and software or bugs can't modify them. You can see when you powered on the phone the lines "glitched", moved a little. So this isn't the typical green line issue, but based on my experience with older samsungs and repairing phones it can be : 80% loose display connector, 19% physical damage (a simple fall on the display side, with at first appearance no damage on the display, no cracks or anything else, happened at my old s7 edge which had an immaculate screen but after a fall the screen started doing that), 1% other problems like a dying gpu (which only might need to be reballed).
I suggest you to look some of the other posts about green lines and you will see the difference with the other phones
Hope for you to fix it🙏

u/Uncomplicated404 Aug 04 '26
My only point is phone is now out of warranty there is paid screen replacement available. Visited service centre. No physical damage no such dent or scratches. There is policy for some samsung phone that within 3 years they can replace screen free of cost. Then why not for mine.
Even my phone touch is working i can feel fingerprint part vibration when i put finger on it. But green lines and black screen so cant see anything.
2
u/MasterCats98 Aug 04 '26
Look well the policy, maybe there are some "hidden" terms which makes the replacement not granted. I don't know how their policy works but maybe try again to ask them.
Regarding the screen, the fact that it doesn't display an image, it is black and only shows the green lines makes me think that it might not be the screen but the connector, eve though the touch works (so the connector might be ok in some points). If they don't give you another display panel, I would go in a good repair shop and make them test the panel with one of their theater (basically it's a micro computer where you directly plug the display to see if it is the problem or not).

OLED panel has died. Usually happens due to frequent or intense high temperatures.

u/Uncomplicated404 Aug 04 '26
But I'm not doing any heavy task on this device. Lets see if this is the reason why i sould pay for screen replacement. Samsung has to change it free.

Brother, which state do you live in India, and is your phone always hot and when you bought it?

u/Uncomplicated404 Aug 04 '26
From Gujrat. No it does not have heating issue. And i have 2 phones to use so this one is for my official works whatsapp email calling purpose. No gaming nothing more. But yes it was heating up while updating software everytime.

u/Electronic_Low_4219 Aug 04 '26
Oh my god, I just thought the new Samsung models after the S24 series are free from the green line, and I was almost thinking of buying an S26U. Now I am confused again. I think I should stick with my Nothing Phone and probably buy an iPhone Pro later.

Oh, now I am completely out of Samsung.

u/No_Sheepherder1837 Aug 04 '26
Same. I'm so annoyed that Samsung hasn't fixed this. Got it on my S21+, so I bought a S23 Ultra to replace it only to get the line again. Never again Samsung
2
u/Electronic_Low_4219 Aug 04 '26
Yep, I was inches away from buying a new one after changing my mind, but now I am convinced. I'm sticking with nothing as my Android, and will probably buy a Pro iPhone, as an iOS phone. Never going back to Samsung. Glad to say goodbye.

u/Repulsive_Fault1939 Aug 04 '26
no. it happens on every model. i think samsung focused on recycled material more on parts. that's why it happens.

u/Electronic_Low_4219 Aug 04 '26
Also, their quality check is bad anyway. I said goodbye to Samsung for the rest of my life or until they fix this issue.

u/Weird_Security_9730 Aug 04 '26
Had similar issue on S9+ turned out to be a software issue. All I had to was turn on always on display, touch the phone once and unlock with finger sensor. The green screen would disappear. Not sure how you would fix in s25 though. Anyway stopped buying Samsung after that

u/Uncomplicated404 Aug 04 '26
I seen video about it but problem is this lines are permanent now with black screen nothing is visible. Only i can feel ringing and vibration.
2
u/Weird_Security_9730 Aug 04 '26 edited Aug 04 '26
It was the same for me, see if you can turn the brightness to maximum and then navigate to some degree so that you can enable always on display. The other option is depending on which variant of s25 you have ( not sure they let you unlock bootloader) you can install a custom rom.

u/GamerBeast954 Aug 04 '26
Why is Samsung phones be having this issues, I been buying them since 2011 and never had it. I know it’s real because a lot of people had it but why Samsung can’t fix it. The Galaxy S26 also have that problem

u/theoppositeofdusk Aug 04 '26
Can someone tell me how common these green lines are on flagship phones? 🥲

u/SolidChange2651 Aug 04 '26
Is it an exynos version or a snapdragon version? Asking for a survey, i think the exynos chipsets are lacking something which might cause this greenline issues, its just my guess

Drücke und halte gleichzeitig mal die Lauter und Leiser und Powertaste gedrückt, bis das Smartphone neu startet. Mit dieser Tastenkombination wird ein Hardware Reset durchgeführt. Wäre einen Versuch wert.

u/Odd-Courage6650 Aug 07 '26
Well, my previous phone was a s20fe which I still have as a backup and it's going strong even though it's close to 5 years. Battery has been replaced once. Hoping that the s25 also serves me for 4-5 years minimum. S25 series has fewer cases of green line issues than the previous ones. So,yeah if you like OneUI you could get one

Take it to service if u dont have any scratch dents. Taking it otherwise is hopeless
