Before You Begin Trying the Solutions

As always, before going to the solutions below, we should urge you to take a backup of your phone’s data. You could take the backup to your PC or online like Google Drive and other cloud platforms. Also, you should make sure that the phone has around 60 percent charge.

The more the better in this case. There are many ways to take a backup of your phone. Simply, you can copy and paste all the data manually to your PC. Or else, you can learn the other methods from the web. We will not elaborate on that in this post.

Method #1 Restart Your Android Phone

We admit that it seems the most obvious. You might also think that it will not work. However, many users have reported that after restarting their device, the vertical line issue was fixed automatically.

We think that those issues were software related. So, you can also try to restart your phone to see whether it fixes the issue or not. If not, then you can proceed to the next option.

Method #2 Force Restart Your Android Phone

What is a ‘Force Restart’, you might ask? It is the process of restarting your phone when it is lagging or freezing and doesn’t respond to any touch or press to the buttons.

There are a ton of brands that offer Android phones. So, it is hard to provide the process of ‘Force Restart’ for all of the models. 

Rather, we will show you a basic process that should be common for most of the top brands. So, simply press and hold the power button for up to 20 seconds or until the phone restarts itself.

When you see that the phone is restarting, you can let go of the power button. Wait for the phone to reboot and check whether the vertical lines are still there.

Method #3 Reboot in Safe Mode

If you think the vertical lines on your phone are related to software, then you can try rebooting it in ‘Safe Mode’. By rebooting in safe mode, the phone will restart with only default/pre-installed software that came with it.

So, if any third-party apps were the source of the issue, those will not be available while in safe mode. As a result, you will find out whether the issue is related to any of those 3rd arty apps.

Now, there are a few methods of entering into safe mode in an Android phone. Depending on the phone model and version of the operating system, it will vary phone by phone. So, we will be sharing 2 methods of rebooting in safe mode in the section below.

Process #1 Rebooting in Safe Mode

  • Press and hold the Power button on your phone
  • In doing so, the ‘Power off’ and ‘Restart’ icon will appear on the screen
  • Next, tap and hold on the ‘Power Off’ icon for a few seconds
  • Now, a pop up will appear asking if you want to enter into Safe Mode. So, simply tap on the ‘OK’ option
  • Wait for the Android phone to reboot in safe mode

Process#2 Rebooting in Safe Mode

  • Press and hold the ‘Power’ button to turn off your android phone
  • Next, repeat the process to turn on the device. However, once the startup screen appears, you have to press and hold the ‘Volume Down’ button for a few seconds or until the phone start into Safe Mode

These are 2 of the most common ways of entering into the Safe Mode in android phone. Remember, you can come out of Safe Mode by simply restarting your phone. Now, check whether the lines have disappeared or not. If not, then you can try the next solution.

Method #4 Tweak the Battery Charge Cycle

If the lines are appearing because of any faults in the electric circuit and battery, then you can try this fix. Many users have reported that charging the battery to 100% actually fixed the issue for them. Now, if that doesn’t do it for you.

You should cycle the battery. To do that, you should wait for the battery to discharge to 0%. And then recharge it to 100%. Or you can also, recharge the battery to 100% and then wait for it to discharge to 0%. This would also work as cycling the battery of your android phone.

Method #5 Check the Display of Your Android Phone

In general, if there are any cracks or scratches on the screen of your phone, you should already be aware of that. Because those cracks would be fairly visible. If you find something like cracks on the screen, then you should take it to a repair center as soon as possible.

However, sometimes, the display becomes faulty from the inside. Also, the display connector/ribbon could be loose or faulty as well.

For your information, the display ribbon is also known as a display strip or display flex cable. So, to see if the problem is with the display ribbon cable, you can lightly press various parts of the screen with your finger.

If you see that the lines are disappearing from the screen with your press, then you are in luck. Also, if you find out that with each press, new lines are appearing on the screen, then you should contact a repair center as soon as possible.

Method #6 Perform a Factory Reset

If you are sure that the vertical lines on your phone are because of a software issue, then you should try factory resetting your android phone as a last resort.

Why as a last resort? Because resetting your phone to factory settings will delete everything on your phone. As a result, without any serious need, you should not perform a factory reset.

Now, as you know that there are various types of models and OS versions of Android out there. That is why the method of factory resetting an Android phone would also vary from model to model.
