If a green vertical line appears on an Android phone screen, what should I do? This issue, which can be seen on different brands and models, can be caused by both software and hardware issues. Restarting the phone or deleting a specific application may resolve the problem, but it is generally an indication of a malfunction in the screen panel.
Green vertical line appears on the phone screen
Green lines may appear on the smartphone screen due to various factors. Common causes include disconnected screen film, damaged screen, or operating system errors. Here are the methods you can try against the green line problem.
Check the screen connection (loose connection, cracked screen)
If a green line extends from top to bottom, the cable between the screen and the motherboard may have come loose. To address this, you should detach the screen from the phone and check the connection cable. However, be cautious as there is a risk of damaging the screen when opening the phone’s casing.
Apart from a cable connection issue, your screen may also be cracked. If there are other colors or visible damage on the glass along with the green line, you will need to repair the screen.

Restart the phone
Software issues can occasionally occur on Android phones. Especially if the problem occurred while using the phone, you can try turning it off and on again. This simple step can resolve software-related issues that may cause the green line.
Check the installed applications
Malicious applications you have installed on your smartphone can harm the device. If you suspect that the issue occurred after installing a specific app, you can navigate to Settings > Apps > Installed Apps.
Factory reset the phone
As a last resort, you can perform a factory reset on the phone. Keep in mind that this process will erase all data on your phone, so remember to back up important files beforehand. To restore factory settings, you can follow these steps:
- Step 1: Go to the Settings section on your phone.
- Step 2: Find the Backup & Reset category.
- Step 3: Follow the path for Factory Data Reset.
- Step 4: Click on Reset Phone > Erase Everything.
- Step 5: After the second confirmation, all your data will be erased, and the phone will be reset.
If the green line continues to appear on the screen after the reset, it is most likely a hardware issue. In that case, you may consider replacing or repairing the screen.
