Horizontal Lines on Oppo Phone Screen? Here’s What You Can Do

Noticing horizontal lines on your Oppo phone screen can be frustrating  especially if your phone was working perfectly fine just moments ago. Whether you’re scrolling through Instagram, watching YouTube, or replying to messages, these mysterious lines can interfere with everything. But don’t worry  you’re not alone, and this issue is often fixable.

In this article, we’ll go over the common reasons why these horizontal lines appear, how to fix them at home, and when it’s time to visit a service center.

What Causes Horizontal Lines on Oppo Phone Screens?

There are a few possible culprits behind this issue. Some are minor and temporary, while others might need a bit more attention. Here’s a quick breakdown:

1. Software Glitches

Sometimes, the problem isn’t hardware at all. A minor system bug, recent update, or a stuck process can cause temporary display issues.

2. Screen Damage

Have you dropped your phone recently? Even if the glass isn’t cracked, internal damage like a faulty LCD or loose display connection can cause lines to appear.

3. Overheating

Oppo phones are packed with powerful processors. If your device has been running heavy apps or games for long periods, overheating might disrupt screen performance.

4. Water Exposure

Even splash-proof models aren’t waterproof. Exposure to moisture can lead to short circuits or screen distortion.

5. Hardware Failure

In rare cases, it could be a manufacturing defect or a problem with the GPU (Graphics Processing Unit).

How to Fix Horizontal Lines on Oppo Phone Screen

1. Restart Your Device

This is the simplest solution  and sometimes the most effective. A quick reboot can reset display drivers and eliminate any temporary glitch.

2. Boot into Safe Mode

Safe Mode disables third-party apps and helps you check if an app is causing the issue.

How to do it on Oppo:

• Hold the Power button until the shutdown menu appears.
• Tap and hold Power Off until you see the Safe Mode prompt.
• Tap OK to reboot in Safe Mode.

If the lines disappear, an app is likely the cause. Uninstall recently installed or suspicious apps one by one.

3. Check for Software Updates

Oppo frequently releases updates to fix known issues. Go to:

Settings > About Phone > Software Update

Install any available updates and restart the phone.

4. Gently Press Around the Edges

Sometimes, especially after a drop, the display connector may loosen slightly. Gently press around the phone’s edges, especially near the screen, to reseat the internal components.

Be careful not to apply too much pressure.

5. Factory Reset (Only If Necessary)

If nothing works, backing up your data and doing a factory reset can rule out deep software issues.

Settings > Additional Settings > Backup & Reset > Erase All Data

When to Visit a Repair Center

If the horizontal lines on your Oppo phone screen persist after trying the above steps, it might be a hardware issue like a damaged screen, faulty motherboard, or GPU malfunction.

Signs it’s time to get it checked:

• Lines remain during boot screen
• Flickering or screen blackout
• Touchscreen becomes unresponsive

Visit an authorized Oppo service center to get an expert diagnosis. If your phone is under warranty, the repair might even be free.

Preventive Tips

• Always use a good-quality screen protector and case.
• Avoid using your phone while charging or under direct sunlight.
• Don’t install unknown third-party apps.
• Keep your software updated.
• Handle your phone gently to avoid pressure or accidental falls.
