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

Green line is totally work of excessive heating which generated during gaming and updating phones https://r2.community.samsung.com/t5/Tech-Expert/Green-Line-Issue-Is-it-an-update-problem-What-s-the-...

Abdul, tumhe nahi pata main apne phone ka kitna dhyan rakhta hoon. Agar tumhare paas koi solution hai toh batao, warna please rehne do. Main yeh phone sirf chat, call aur resume update karne ke liye use karta hoon. Mujhe laga background mein auto-update chal raha tha. Uske baad jab maine phone resume kiya, toh ek line dikhayi di

Main pagal nahi hoon jo community mein bewakoofi karoon. Maine 93% pe green line dekhi — uske baad maine apne doosre phone se photo le li. Agar main ise 98% pe resume karta hoon, toh yeh next stage pe chala jaata hai: installing

Customer care rejected my claim for S21FE due to a small dent on phone frame

Samsung service center and samsung customer support don't provide free replacement send email to Samsung care try

There are not matter related to free replacement but once phone is open there are not finishing like company fitting inaddition freereplace ment agar deta bhi hai samsung to tumhara time service center ka chakkar vo sab hesitation rehta hai uska kya aur ye issue bahot saal se hai aur vo bhi sabhi model me to uska mtalab to ye hua ki ham service center ka chakar katane aur company fitting premium phone ko open karke dabba banake ke paise dete hai samsung ko. Indirectly samsung ko hi nahi pata hai ki ye issue ka resolution kya hai. Foram me kuch likhta hai to suggest karate hai like ki yesa karo download k baad installation k time pe phone ko cool rakho extra...are bhai itna limitation hai to why you are not inclusingall this norms in main advertising during sell. Afterall samsung doesnt have permenant solution for this issue.

I am also facing the same issue

Last year they had replaced the screen

And 2 days back I got green line again
I had contacted the customer care they are saying it is 1 time replacement
Now you need to pay
Note: I didn't even updated
Device is in mint condition
