How to Fix Green Line or Dead Pixels on Xiaomi AMOLED Screen
Fix xiaomi green line screen and redmi dead pixels. Resolve poco amoled line and xiaomi screen defect with hyperos display issue guide.
A green vertical line or cluster of dead pixels on your Xiaomi AMOLED display is almost always a hardware defect — not a software bug. Here's what you need to know.
What Causes It?
- Physical impact — drop damage, even without a cracked glass, can damage the AMOLED panel internally
- Manufacturing defect — some units have a faulty display connector or panel
- Extreme heat or cold — temperature shock can damage OLED pixels
- Aging — very rare on newer Xiaomi phones but can appear on older models
Is It a Software Issue?
Test it: Take a screenshot of the screen. If the line appears in the screenshot → software issue. If the screenshot looks normal but you see a line on screen → hardware issue.
Software Fixes (If Screenshot Shows the Line)
- Restart the phone
- Update HyperOS via Settings > About Phone > System Update
- Factory reset
