Complaints about mysterious lines appearing on smartphone screens have more than doubled in Singapore this year, with Samsung users being the most affected.
According to data from the Consumer Association of Singapore (CASE), 31 complaints about screen line issues were lodged as of 14 November 2024, compared to 14 in 2023 and only four in 2022.
Of the 49 complaints filed over the past three years, 48 were directed at South Korean tech giant Samsung, while the remaining one was against the Chinese brand OnePlus.
Many Cases in Galaxy Phones
Many of the affected users reported that vertical green, pink, or white lines began appearing across their screens after a software update.
CASE President Melvin Yong noted that complaints primarily focused on this issue following updates on Samsung’s Galaxy S21 series, including the S21 Ultra and S21 FE models. Other affected models included the Galaxy A73, Galaxy M21, Galaxy S22 series, and Galaxy Z Flip 3.
Experts suggest that the issue is likely linked to hardware defects, though software updates could exacerbate the problem. A faulty connection to the AMOLED display—a type of organic light-emitting diode (OLED) screen—is commonly cited as the cause.
Phones using LCD screens appear unaffected.
Additionally, some reports claim that overheating during or after a software update might lead to hardware damage, potentially triggering the lines.
Physical damage, such as dropping the phone, could also be a factor.

What to Do If You’re Green-Lined
For users noticing such lines, the first step is to restart the device.
If the issue persists, it may indicate a hardware problem that requires a display replacement. Samsung advises customers to visit authorised service centres, where warranty coverage may allow free repairs or replacements if there is no external or water damage.
Samsung has offered one-time free screen replacements in markets like India for selected models, while OnePlus has extended free lifetime screen warranties in some regions.
However, no specific resolution plan has been announced for Singapore.
To minimise risks, experts suggest delaying software updates or performing them in cool, well-ventilated areas to prevent overheating.
Unfortunately, there is no guaranteed way to avoid the issue entirely.
Oh, wait, there is.
How about not using your phone 24 hours a day?
