How to Fix the OnePlus 13 Green Line Issue

Many users previously complained about seeing a vertical green light on their OnePlus devices. Some green line victims say the issue is usually caused by a short circuit on the display drivers, which can be due to water damage or a physical drop. Some say that the issue can also occur after an OTA update. OnePlus addressed this matter by offering a lifetime warranty program for its smartphones, which covers the cost of replacing the display on affected phones.

If you recently experienced this issue with your new OnePlus 13, it’s not easy to bat an eye, especially when you’ve spent money on a “high-end” device. In this guide, we’ll learn some troubleshooting tips to deal with the OnePlus 13 green line issue before seeking help from professionals.

If you've noticed a green line emerging on your OnePlus 13 screen, you're probably wondering what caused it and how you can fix it. You may also feel like OnePlus could do better. However, some say that the green line issue is not a OnePlus-specific problem and that it can affect OLED screens from other brands as well. Here’s a proof shared on X.

Many OnePlus customers have been perplexed by this issue, and although it is frustrating, the first step in fixing it is figuring out its underlying reasons. Let’s dig into the details below.

Sometimes, the green line is caused by a software glitch. The OnePlus 13, like other current smartphones, uses advanced software to handle its high-resolution display, making it better than average phones. Bugs in the operating system or recent updates can occasionally cause issues with how the screen renders graphics, resulting in anomalies such as these green lines.

Have you lately dropped your phone or put pressure on the screen, even unintentionally? Physical impact is a frequent source of display issues, especially green lines. Even while the OnePlus 13 is designed to withstand minor impacts, too much force can harm the display and other sensitive internal parts. After an impact, damage may not always be apparent right away but may show up later as the hardware ages. We recommend using a OnePlus 13 Thin Case made of durable and strong materials to provide additional protection to your phone while remaining minimalist.

The OnePlus 13 has a gorgeous OLED display, but even the best technology isn't immune to defects. A green line may indicate damage to the display panel. OLED screens use millions of tiny pixels that generate light independently, and if any of these pixels malfunction or their controlling circuitry fails, you could experience undesired lines or color distortions.

Now that you know what's causing the green line on your OnePlus 13, it's time to take action.

To begin, look at your phone's recent history to narrow down the cause:

• Did you recently install a software update? If yes, it might be a software issue.

• Has your phone experienced any physical impact or pressure?

• Have you exposed your phone to harsh environmental conditions?

• Did the problem appear gradually or suddenly?

Answering these questions will help you discover whether the problem is software-related, hardware-related, or due to external factors. But if you didn’t find an answer in any of the aforementioned, here's a guide on how to fix it.

This is a universally applied solution to almost any tech-related issue. Sometimes, a simple restart can resolve temporary glitches.

Step 1: Locate the Power Button:

Find the power button on your phone. Usually, it's on the side or top of the device.

Step 2: Press and Hold the Power Button

Holding down the power button for a few seconds will display a menu or an option to restart or switch off the phone.

Step 3: Choose "Restart"

Tap "Restart" if it's an option. Your phone will turn off and back on by itself.

Step 4: If "Restart" Is Not Available

Choose "Shut Down" or "Power Off" instead. Wait until your phone is completely turned off.

Step 5: Manually Turn the Phone Back On

Once the phone is off, press and hold the power button again until the startup animation or logo appears on the screen.

Step 6: Wait for the Device to Boot

Give the phone a few moments to reboot and load the OS. If prompted, enter your PIN or password.

That's it! We've successfully restarted your phone.

Software isn't often perfect. That’s why developers from other brands push timely updates. OxygenOS is no different; it has its pros and cons. An error in installing a previous version of the software might be the culprit for a green line. Updating your phone’s software to the latest version could solve the problem.

Step 1: Connect to Wi-Fi

Ensure your phone is connected to a stable Wi-Fi network, and avoid using mobile data for the update.

Step 2: Charge Your Phone

Make sure your battery is above 50%. If it’s below, connect your phone to a charger to avoid interruptions during the update process.

Step 3: Open the Settings App

Unlock your phone and tap the Settings icon from your app drawer or home screen.

Step 4: Navigate to System Updates

Scroll down and select About Device or System, depending on your OxygenOS version.

Tap Software Update or a similar option.

Step 5: Check for Updates

Choose Check for Updates to see if a new version of OxygenOS is available for your device.

Step 6: Download the Update

If an update is available, tap Download and Install. Afterward, the new software package will start downloading.

Step 6: Install the Update

Once the download is complete, tap Install Now. Your phone will prepare for installation and automatically restart.

Step 7: Wait for Installation to Finish

Allow your phone to complete the update process. This may take several minutes. Your phone will restart when the installation is complete.

Step 8: Verify the Update

Once your phone has restarted, return to Settings > About Device and confirm if the software has been updated to the latest version.

Note: You can manually update via the Oxygen Updater app or the OnePlus support website if the update isn't accessible through settings.

Physical impact on the Display is another probable cause for the frustrating green line. You can check your phone’s Display Settings to eliminate this problem.

Step 1: Unlock Your Phone

• Turn on your OnePlus 13 and unlock it using your password, PIN, or fingerprint.

Step 2: Open the Settings App

• Tap the Settings icon on your app drawer or on the home screen.

Step 3: Navigate to Display Settings

Step 4: Explore Display Options

• In the Display settings, you’ll find several options to customize, such as:

  • Brightness : Adjust the screen brightness or enable Adaptive Brightness.

  • Refresh Rate : Choose between different refresh rates.

  • Resolution : Adjust the screen resolution, if applicable.

  • Dark Mode : Enable or schedule dark mode.

  • Color Settings : Customize the color profile.

  • Font and Display Size : Change the font size, style, or screen scaling.

  • Eye Comfort Mode : Enable the blue light filter to reduce eye strain.

Step 7: Exit Settings

• Once your display settings are customized, press the back button or home button to exit.

Step 8: Test Your Changes

• Use your phone as you normally would to see how the new display settings feel. Adjust further if needed.

Pro-Tip: For advanced display tweaking, search for features like Ambient Display or Always-On Display under the Display settings menu!

Your device is well-protected with a reliable phone case, but physical impacts can still occur on occasion. These could occasionally result in screen problems like a green line. If you think this is the reason, follow this helpful guide to check whether you can resolve it yourself or if it’s time to seek professional help.

Step 1: Inspect the Screen

The first step is to examine the display for cracks, scratches, or discoloration. If there are none of those, check for unresponsive areas by tapping or swiping across the screen. Look for any dead pixels or flickering by using an image of a solid color background.

Step 2: Examine the Body

Next would be to make sure to check the phone’s frame and back panel for dents, scratches, or cracks. Inspect the edges, especially corners, as they are most prone to impact damage.

Step 3: Check the Buttons

You can check the power button, volume buttons, and alert slider to ensure they click and function properly. Search for any looseness or irregularity in button placement.

Step 4: Inspect the Charging Port

It’s important to look inside the USB-C charging port for debris, lint, or any visible damage. And then, test the port by connecting a charger to ensure a secure fit and proper charging.

Step 5: Check the Speakers and Microphone

Take a look at the speaker grills and microphone openings for blockages or damage. Next is to test the sound quality by playing an audio or recording your voice.

Step 6: Examine the Cameras

Don’t forget to check the camera lenses for cracks, scratches, or dust. Take a few photos and videos to confirm the camera focuses correctly and has no visible defects.

Step 7: Inspect the SIM Card Tray

On your OnePlus 13, remove the SIM card tray and check for any bending or damage, ensuring the tray fits snugly back into the slot without resistance.

Step 8: Check for Water Damage

This is one of the most important steps in troubleshooting physical damage. On your OnePlus 13, you can find an LDI (Liquid Damage Indicator) near the slot for your SIM cards. If it has turned red or pink, your device has likely been exposed to water.

Step 9: Use the Phone Normally

Another important step of troubleshooting is to use your phone for daily tasks to identify any subtle issues such as: overheating, reduced performance, or abnormal vibrations.

If you find any physical damage, contact OnePlus support or visit an authorized service center for professional inspection and repair.

Safe Mode is a great way to troubleshoot problems and keep your phone running smoothly. Every device has this function, and some users, even other brands, consider it as the last option before you need to go to an authorized service center.

Here are the steps to launch Safe Mode in your OnePlus 13:

• Understanding Safe Mode 

  • Safe Mode disables all third-party apps, allowing you to identify if a problem is caused by these apps or the system.

• Power Off your Phone

  • Press and hold the Power button until the power menu appears.

• Access Safe Mode Option

  • On the power menu, tap and hold the Power Off option until a pop-up appears and says: “Reboot to Safe Mode.”

• Confirm Entry into Safe Mode

  • Tap OKAY or Yes to restart your phone in Safe Mode. Your phone will restart, and you’ll see "Safe Mode" displayed at the bottom corner of the screen afterward.

• Test Your Phone 

  • In Safe Mode, use your phone as you would and check if the issues (e.g., green line, lagging, or overheating) persist. If the problem is resolved in Safe Mode, it’s likely caused by a software glitch or a third-party app.

• Exit Safe Mode

  • Restart your phone by pressing and holding the Power button and selecting Restart. Your phone will reboot into standard mode, and all applications will be re-enabled.

• Identify Problematic Applications

  • If the green line issue doesn’t occur in Safe Mode, uninstall recently downloaded apps one by one to identify the culprit. To uninstall an app, go to Settings > Apps > App Management, select the app, and tap Uninstall.

• Contact Support

  • If the green line issue persists even in Safe Mode, it might be a system or hardware problem. This is where you need to contact OnePlus support for assistance.

If you want to do a brief check-up before heading to a service center, just punch in *#808# on your phone’s dialer, and you'll access a hidden menu with diagnostic options. This is your OnePlus 13’s Diagnostics Tool. Once you finally have access, you can test the touchscreen, accelerometer, gyroscope, and other sensors for proper functionality.
