OnePlus smartphones, known for their AMOLED displays, have faced a recurring green line issue affecting multiple models over the years.
This article covers all affected devices, including the latest OnePlus 13 and OnePlus 14 models, the causes, and OnePlus’s current solutions.
What Is the Green Line Issue?
The green line issue is a display defect where a thin vertical green line appears on the screen, visible regardless of content. This issue worsens over time and usually cannot be fixed by software updates.
OnePlus Models With Green Line Issues
- OnePlus 7 Series: Early cases reported; less widespread.
- OnePlus 8 Series (8, 8 Pro, 8T): Especially the 8T had widespread complaints.
- OnePlus 9 Series (9, 9 Pro, 9R, 9RT): Among the most affected.
- OnePlus 10 Series (10 Pro, 10T): Moderate issue reports.
- OnePlus 11 Series: Green line complaints continue.
- OnePlus 12 Series: Many active user complaints; repair delays reported.
- OnePlus 13 Series: Despite durability testing, green lines still appear due to hardware defects, software bugs, or physical damage.
- OnePlus 13R: Reports of green lines persist, though less frequent than previous models.
- OnePlus 14 Series (NEW): No confirmed green line cases as of now, thanks to improved manufacturing and new protective layers.
Are the Latest Devices Safe?
OnePlus 13 / 13R:
Still not fully safe. OnePlus added a new edge bonding layer and enhanced sealing to reduce AMOLED aging, but some users still face green line issues. Causes include software glitches, display defects, and physical pressure.
OnePlus 14 Series (NEW):
No green line cases confirmed so far. OnePlus has made significant changes, including new internal materials, better bonding, and more display tests. These improvements appear to be effective, but it’s too early for long-term conclusions.
Causes of the Green Line Issue
- Hardware Defects: Pixel degradation or faulty display circuits.
- Environmental Factors: High heat and humidity (especially in Asia) accelerates OLED aging.
- Software Bugs: Updates sometimes trigger the issue unexpectedly.
- Physical Damage: Drops, bends, or pressure can lead to display separation and green lines.
