A persistent green line on a Samsung Galaxy S20+ is a display problem, not something you can count on fixing with a setting or software utility. Samsung recommends display repair when lines appear. First document the symptom and check warranty and service options for your exact device and region; then choose professional inspection or, if you have the right parts and repair skills, replacement of the complete screen assembly.
What a green line tells you—and what it does not
Samsung says vertical or horizontal lines can appear across parts of a Galaxy screen and recommends display repair. A green line is therefore a reason to have the display assessed, but the line alone does not identify its specific cause or establish whether your device qualifies for warranty coverage.

The S20+ has a 6.7-inch WQHD+ Dynamic AMOLED 2.0 display with 3200 × 1440 resolution and support for 60 Hz and 120 Hz refresh rates, according to Samsung Electronics America’s 2020 product brief. Those specifications describe the model; they do not diagnose an individual phone. Samsung’s guidance on lines and unusual screen colors recommends display repair.

Document the problem
- Take a clear photo of the line and note when it first appeared.
- Record whether the glass is visibly damaged, whether the phone was exposed to impact or pressure, and whether the display still responds to touch.
- Have your model and device identifiers ready when you contact service. Samsung US says the model, serial number, or IMEI can help start a repair request; dialing
*#06#displays the IMEI and serial number.
Check coverage and service availability
Review the device’s warranty status through your Samsung Account and confirm the available service options with Samsung in your region. Samsung US says repair cost depends on diagnosis, warranty status, and repair type; there is no universal price established for an S20+ green-line repair. Do not assume the repair will be free, even if the line appeared without an obvious impact.

Choose between professional service and DIY
| Repair path | What it involves | What to check first |
|---|---|---|
| Professional inspection and repair | Samsung recommends a service-center inspection for lines or unusual colors. Samsung US describes walk-in and mail-in service using genuine parts. | Check local service availability, warranty status, and the diagnosis-based quote. Samsung US repair options |
| DIY screen assembly replacement | The S20+ repair guide describes replacing the complete assembly: display glass, OLED panel, and digitizer together—not simply adjusting software or swapping only the glass. | Confirm exact model and part compatibility, obtain the required adhesive, and assess your experience with a fragile display and heat-and-pry disassembly. iFixit’s Galaxy S20+ screen replacement guide |
How to proceed with professional service
- Use Samsung’s repair or support channel for your country and provide the model and device identifiers, a description of when the line appeared, and your photos.
- Ask for an inspection and a quote before authorizing repair. The cause, warranty determination, and repair type affect the price.
- Choose an available service method, such as a service-center visit or mail-in service where offered, and follow the provider’s instructions for preparing the phone.
What DIY screen replacement means for this phone
A model-specific guide treats the glass, OLED panel, and digitizer as one screen assembly, so a persistent line is not presented as a simple glass-only repair. The guide lists a replacement screen and adhesive; its opening steps involve heating and prying, and it warns that the panel is fragile and can break during the procedure.
If you are considering DIY, verify that the part matches your exact S20+ variant and that you can follow the disassembly process safely. A wrong or incompatible part, or damage during opening, can add to the repair. Check warranty and local service eligibility before opening the phone.

Regional self-repair programs are not universal

That establishes a route described for Korea; it does not establish that the same program, parts, or eligibility applies in other countries.
