Watching your mobile screen with those white or black vertical/horizontal lines is annoying, to say the least. They make the screen look tedious, with icons (apps) and keyboard just faintly visible. In short, it’s really hard to use a phone with these lines appearing on the screen. Typically, this issue is associated with the LCD, caused by a faulty hardware component in your device due to some accidental fall or water damage – and can only be sorted at a phone repair center. However, sometimes the culprit could be an app or software glitch, hindering the functionality of key components like display assembly or motherboard. In that case, you might not need a repair service as there’re some troubleshooting ideas to tackle the situation at home.

In this article, we will discuss such promising solutions you can try if your phone screen develops these horizontal or vertical lines. 


Take the Data Backup Beforehand

Before you head on to the fixes, let’s make your phone data safe. Sometimes, these lines are irreversible, and even the solutions you’re up to try may be followed by some sort of data loss. Therefore, the first thing you should do is take the back up of important files and apps in your device. Some popular ways for data back in Android devices are via 

  • USB Connection
  • Google Account
  • Bluetooth
  • Wi-Fi

You can choose the option you’re most comfortable with. In case you’re not sure about the process, it’s better to take help from a professional repair center. For Infinix, Itel, and TECNO users, Carlcare Service- being their official service center for these brands- is a recommended place to go.

Now, the Solutions to Fix Horizontal or Vertical Lines on your Android device.

Restart your Phone

 If the lines are appearing due to some minor glitch, a simple restart will fix it. Pressing the volume button for a couple of seconds will bring up a reboot menu. Tap on the “Restart” option and let your phone complete the process itself. 

Cycling the Battery

The second solution we would suggest you is, cycling your phone battery. If there’re white lines on the screen, this solution may prove effective. A battery cycle is when you charge a mobile to 100%, let it drain to 0% again. Many times, the lines disappear as soon as you charge the battery fully.  

Use your Phone in Safe Mode

If the above methods don’t work, it’s time to try this masterstroke. Using your phone in a safe mode will confirm if the lines are because of some faulty app or software. 

Here’s how to enter safe mode:

  • Press and hold the Powerbutton, simply like you do when switching off the phone
  • When the Power Off icon appears, Tap and hold it for a second or two.
  • Click on ‘Reboot to Safe Mode’ when the option pops up. Select OKand let the device reboot. 

Check if the lines are gone! If yes (hopefully), then a third-party app is the culprit. Now uninstall the latest downloaded applications until the issue is gone. OR you should try the Solution:4  

If the lines are still visible. Then the issue is most likely due to some hardware failure- and the best option for you is to take your device to a reliable repair center. 

Factory Reset Your Phone

It won’t be aggregation if you call “Factory Reset” mother of all solutions. It fixes most of the issues caused by an app or software glitch. The process actually brings your phone back to the factory setting by erasing all the apps and files you’ve downloaded post your phone purchase. 

On most phones, 'Factory Reset' can be done via the Settings App. Follow the below steps: 

  • Open Settings >> System >> Backup and Reset.
  • Tap on Factory reset option
  • Tap on Reset Device.
  • Enter in your lock screen PIN and Hit Next. 
  • You’ll be asked to confirm that all data will be erased by tapping on Delete All or Erase Everything option. 

Note: Remember, Factory Reset will delete all your mobile data, so don’t forget to take the backup before you try this process.
