Introduction
Noticing a green vertical line on your OnePlus 11 screen can be disconcerting—it interrupts the visual experience and raises questions about both the cause and remedy. This issue, though rare, has been reported by users and addressed by OnePlus. Let’s unpack the potential causes, relevant diagnostics, and what steps you can take.
Underlying Causes of a Green Line on AMOLED Displays
Hardware Defect in AMOLED Panel
The OnePlus 11 uses an AMOLED display, a technology known to sometimes develop vertical lines due to panel defects. These can stem from tiny manufacturing faults or weaknesses in screen connectors. Even minor pressure or flexing can trigger these issues.
Physical Stress or Impact
Even absent overt cracks or drops, internal stress—like pressure from tight phone cases or bending—can damage connectors or delicate flex cables between display and logic board.
Moisture Intrusion
Exposure to humidity or moisture, even in seemingly protected environments, can affect display circuits, leading to discolored streaks—including green.
Software Glitches (Less Likely)
Although less frequent, software bugs or driver-level issues could theoretically manifest as green lines under certain circumstances. However, once a display element is physically compromised, software fixes are unlikely to resolve it.
Diagnostic Steps to Narrow Down the Cause
Here’s a systematic approach to identify whether the issue is hardware-related or software-related:
- Restart the Device – Often resolves temporary display glitches.
- Boot into Safe Mode – If the line disappears, it could be third-party apps or software running in the background.
- Check for Updates – Visit settings to see if a system update addresses display anomalies.
- Factory Reset (Optional, Last Resort) – If nothing else works and you suspect software faults—but back up your data first!

If the green line remains after these efforts, it likely signals a hardware failure.

Amplifying Factors Specifically for OnePlus 11
Panel Supplier Transition
OnePlus 11 reportedly used Samsung-made AMOLED panels, which have shown susceptibility to green line defects across brands, including Apple. From the OnePlus 12 onward, they transitioned toward BOE panels, which currently show fewer such incidents https://www.reddit.com/r/oneplus/comments/1kuaacv/one_plus_11_green_line_issue/?utm_source=chatgpt.com
