In this blog post, we want to let you know what the mysterious green line always appearing on the phone screen means and how you can repair it by yourself before paying a service center for some very basic steps that you can easily perform by reading the following.
What Is This Green Line?
The green line can flicker and appear temporarily or permanently. The green line can be a single one as well as a number of them can also be there, and there may be some form of discolouration of various other colours like pink, white, etc.
It appears everywhere when the phone is switched on or when the display is on, including the home screen, the lock screen, and the Always-On display.
What Can This Green Line Mean?
A green line appearing on your used phone screen is usually a symptom of a hardware problem, like a loose, damaged, or defective display connector (the cable connecting the screen to the motherboard). These are usually caused by physical damage like dropping your phone, water exposure, or excessive pressure on the screen as this can corrode internal components, leading to display issues like green lines.
Dropping your phone or applying significant pressure to the screen can damage the display connector or a loosened display connection can also be a reason.
Restart Your Phone
As already mentioned above, a green line on the screen is a hardware issue. This means there is nothing wrong internally, so a simple restart won’t necessarily fix it, but who can tell maybe you have good luck!
You can restart your phone for self-satisfaction to confirm that there is no problem with the software.
Restart In Safe Mode
Booting your phone in safe mode can help you see if the green line disappears, which would indicate a problem with a recently installed app.
Safe Mode prevents anything from launching on your phone apart from the essentials. This is a good way to see if you have a software problem. If the green line goes away in Safe Mode, then you know you have a problem with an app, a setting, or the operating system.
How To Restart A Phone In Safe Mode?
To restart a phone in safe mode, follow the following:
- Press and hold the power button along with the volume down button simultaneously
- Select “Power off” when the power options menu appears
- Continue to hold until the “Safe mode” option appears
- Tap it to confirm
Outdated Software Is The Culprit!
Outdated software can also sometimes cause display issues. Check for and install any available system updates. Ensure your phone has the latest software updates. Check to see if your phone has any operating system updates available. If there’s a problem with your current version of Android, the update may fix your problem.
How To Do A Software Update On An Android?
- Open your phone’s Settings.
- Tap System.
- Select Software update.
- Tap Check for updates.
- If an update is available, follow the prompts to download and install it
How To Do A Software Update On An iPhone?
- Open Settings
- Click on General
- Tap on Software Update
- If updates are available, click Download and Install
- If there are multiple updates, choose the one you want to install and tap Install Now
- If asked, enter your passcode
- Then, tap Install Now
Something Fishy In The New Apps!
Uninstall apps that you had recently installed before the green line appeared. If you’ve installed any apps recently, uninstall them and see if the green line disappears. If the green line is caused by an incompatible or malfunctioning app, removing it may fix your problem. If you’ve made any settings changes recently, try undoing those changes as well.
Renew Your Phone!
You can perform a factory reset but don’t forget to save or back up your important files or data first. This step is most likely to eliminate any software-related issues. If the green line disappears after a factory reset, the issue was likely software related.
How To Do A Factory Reset On An Android?
- Open the Settings app, then search “Reset”.
- Tap Erase all data in the results.
- Tap Erase all data on the Reset options screen, then tap Erase all data and enter your password or PIN to confirm your decision.
How To Do A Factory Reset On An iPhone?
- Go to Settings
- Tap on General
- Click on Transfer or Reset iPhone.
- Tap Erase All Content and Settings.
- If asked, enter your iPhone passcode or Apple Account password
- Tap Continue to confirm
If the green line remains after trying these steps, it could be a hardware issue and you should contact your phone manufacturer for repair. If the warranty period of your phone is not over yet, you can also see if this issue is covered by the warranty.
We hope these steps will help you to understand the problem in depth and what are how you can solve it.
