How to Run the OnePlus Screen Test
- Open this page on your OnePlus phone in Chrome or any other browser.
- Set your screen brightness to maximum and turn off dark mode and night mode.
- Remove the screen protector or wipe it clean. Dirt can look like a pixel problem.
- Start the display test and watch each full-screen color carefully.
- Run the touch test and drag your fingers over the whole screen, including the edges.
- Run the burn-in test and look for faint shadows or ghost images.
- Note any problem, then compare it with the table below.
What Does Each Test Check?
Display and Color Test
The screen fills with pure red, green, blue, white and black. A healthy display shows one clean, even color. Spots, lines or tints mean a problem.
Dead and Stuck Pixel Test
A dead pixel stays black. A stuck pixel stays on in one color, such as red or green. White and black screens show them best.
Touch Test
You draw on the screen to see if every area responds. It helps you find dead zones, lag and ghost touches, which means taps that happen on their own.
Burn-In Test
Gray and solid color screens help you spot image retention, which is a faint shadow of an old image like a navigation bar or keyboard.
What Problems Can You Find?
| Problem | What you see | Likely cause | What to do |
|---|---|---|---|
| Dead pixel | Tiny black dot | Pixel stopped working | Cannot be repaired, check warranty |
| Stuck pixel | Tiny bright red, green or blue dot | Pixel stuck on | May fade, otherwise replace screen |
| Green or pink line | Vertical line across the screen | Display hardware fault | Contact OnePlus service |
| Burn-in | Ghost image on gray screen | OLED pixels aged unevenly | Lower brightness, reduce static content |
| Color tint | Green, yellow or pink shade | Panel fault or wrong color mode | Check color mode, then service |
| Dead touch zone | Taps not working in one area | Digitizer fault or screen protector | Remove protector, then service |
| Ghost touch | Screen taps by itself | Damaged digitizer or dirty charger noise | Try another charger, then service |
Dead Pixel vs. Stuck Pixel
People mix these up, but the difference matters.
Dead Pixel
Always black, because it gets no power. It almost never goes away.
Stuck Pixel
Always lit in one color, because the pixel is stuck on. It sometimes goes away after a few days.
OLED Burn-In on OnePlus Phones
Most OnePlus phones use AMOLED screens, and a few budget Nord models use LCD. AMOLED gives deep blacks and bright colors, but each pixel makes its own light, so pixels that stay bright for years age faster. That can leave a faint shadow of the navigation bar, a keyboard or a game menu.
How to protect your screen
- Keep brightness at a medium level when you can.
- Use auto-brightness, so the screen is not at full power all day.
- Use dark mode, which lights fewer pixels.
- Avoid leaving the same image on the screen for hours.
- Set a short screen timeout.
OnePlus Display Settings Worth Checking
Before you blame the hardware, check these settings, because they can change how the screen looks.
Screen Refresh Rate
Go to Settings → Display & Brightness. Many OnePlus phones offer 60 Hz, 90 Hz or 120 Hz. A low setting can make scrolling feel slow, even when the screen is fine.
Color Mode
The color mode can change how warm or vivid the screen looks. A strong tint is sometimes just a setting.
Eye Comfort or Night Mode
This adds a yellow shade on purpose, so turn it off before testing colors.
Screen Protector
A cheap or old protector can cause dead touch areas and a dull picture.
Test the Touch Screen with Pointer Location
You can also use a built-in Android tool.
- Go to Settings → About device → Version, and tap Build number 7 times to unlock Developer options.
- Open Developer options and turn on Pointer location.
- Touch the screen. Every touch now shows a trail. If the trail breaks or jumps, your touch screen has a problem.
- Turn the option off after testing.
Checking a Used OnePlus Phone Before You Buy
A screen test is one of the fastest ways to avoid a bad deal. Ask the seller to let you test the phone, and check these points:
- Run all full-screen colors and look for dots, lines or shadows.
- Check the edges and corners for lifting, cracks or yellow spots.
- Test the touch screen in every area, including the keyboard corners.
- Set brightness to maximum and look for dark patches.
- Make sure the display is not a cheap replacement. Replaced screens often look dimmer or have weaker colors.
What Not to Do
- Do not press hard on the screen to fix a pixel. It can crack the panel or make the damage bigger.
- Do not test with a dirty screen or a scratched protector.
- Do not judge colors with night mode or eye comfort on.
- Do not open the phone yourself if it is still in warranty, because it can void the warranty.
- Do not ignore a green line. It often grows over time.
Frequently Asked Questions
Does this test work on all OnePlus phones?
Yes. It works on every OnePlus phone, including the OnePlus 13, 12, 11, 10, 9 and Nord series, because it runs in your browser.
Is the OnePlus Screen Test free?
Yes. It is completely free, with no sign-up and no app to install.
How do I find dead pixels on my OnePlus phone?
Fill the screen with solid red, green, blue, white and black, one by one. Look for small dots that stay black or stay bright in one color.
Can I fix a dead pixel?
No. A dead pixel is a hardware problem and cannot be repaired by software. A stuck pixel may fade by itself over time.
What is a green line on a OnePlus screen?
It is a vertical line that appears on the display. It is usually a hardware problem with the panel, and it often needs a screen replacement.
How do I know if my screen has burn-in?
Open a gray screen and look for faint shadows of buttons, bars or icons. If you see them clearly, your OLED has some burn-in.
Why does my touch screen not work in one area?
It can be a dirty screen, a bad screen protector or a damaged digitizer. Remove the protector, clean the screen and test again.
Does the test store my data?
No. The test runs in your browser, and nothing is uploaded or saved.
