Green Line Issue After July Security Patch Update

[sripraveen]

Hi @sumsungsupport, @Samsungmember

I received the July 2025 security patch update on my device early yesterday. After installing the update, I noticed a green line appearing on my screen. This issue started immediately after the update and was not present before.

Has anyone else experienced this after the latest update? Is there any official acknowledgment or fix from Samsung?

Device Model: Galaxy S21FE exynos

Please help or advise

Visit service center if your device date of purchase is after 2023 then only 500rs charge you have to pay no extra cost n one condition no physical damage

I got the same problem after the June update, luckily they replaced the screen for only ₹502 but now I am afraid of updating the phone because the free screen replacement is a one time offer.

Happy for you! Just a suggestion try not to update again, because some users are saying the green line issue is mostly happening on Exynos models. Could you please share which processor your phone has?

Exynos, and thanks I am holding the update for now.

**bleep** feku baaz.Installing download?Toh jhatu kyu resume download dekha raha hain.And resume download itself means neither download is installed nor the device is updated.Find better reason for greenline in your device which is ofc definetly not due to Software update

don't spill without knowns First of all throwing random terms like 'resume download' without context doesn't prove your point. 'Resume download' appears when a download is paused that has nothing to do with whether an update caused the issue or not. Green line issues can occur due to software updates triggering existing hardware faults, especially on AMOLED displays. If you’ve got a better technical explanation, bring it with facts not just slang and noise otherwise, take a seat. Abdul **f**k**

What is random term you bozo?It is clearly visible from screenshot you were downloading the July Patch but paused the downloading at the last moment with 98% done.And you saying you installed the update?And all those Amoled lectures I know it better then you bozo.Green Lines appears due to excessive heating while gaming or even installing updates not due to software issues you bozo.So take the back seat and shut your fuc.ken mouth.I mentioned what I saw from the screenshot and the screenshot and your words both contradicts themselfs.
