Green or pink line on your Samsung screen?
A thin green, pink or white line running down a Samsung Galaxy screen is one of the most common AMOLED faults we see. It's usually a fault inside the display panel itself, and it rarely goes away on its own.

Signs you may notice
- A single vertical line, usually green, pink or white
- Line appears after a drop, or with no obvious cause
- The line doesn't show up in screenshots
- More lines appearing over time
Safe checks to try first
- Take a screenshot and look at it on another device. If the line isn't in the screenshot, the fault is in the screen hardware.
- Restart the phone and boot into Safe Mode to rule out an app.
- Install any pending system update.
- Check whether the line changes when you press gently near the edge (don't press hard).
Stop and bring it in if…
- The screen also flickers or goes black
- Touch stops working near the line
- The phone was recently wet
What usually causes it
One symptom can have several causes. These are the most common ones.
AMOLED panel failure
The connections inside the display panel fail, lighting a column of pixels permanently.
Drop or pressure damage
Impact can crack internal layers without cracking the glass.
Display connector issue
Less often, a loose or damaged connector on the board.
What our technicians do
We test the phone with a known-good screen where possible to confirm the panel is at fault, then replace the display assembly. On Galaxy S-series flagships we usually fit a screen pre-assembled on the frame for the best fit and seal.

Will a software update fix the green line?
Rarely. If the line doesn't appear in screenshots, the fault is in the screen hardware and a replacement is the reliable fix.
Can I keep using the phone?
Yes, but lines often multiply over time. Plan a screen replacement before it gets worse.
