Why are there lines on my mobile screen?
Publicado por PabloIf you have come this far, it is possibly because lines have appeared on your phone screen because it is broken, or due to other problems related to the display of elements on your screen.
This is a common problem that can occur for different reasons, and it is really annoying not being able to work correctly with our device due to these types of LCD issues.
Horizontal or vertical lines on the mobile screen appear due to a software or hardware malfunction of the phone. Here we look at the solutions.
So, the first thing you should know is that generally, the appearance of vertical or horizontal lines is due to a malfunction of the LCD or because it is broken, either because water has entered or it has suffered a fall.
Another issue that can cause this type of problem is a software error causing these kinds of colorless pixels or incorrect tone display. On some occasions, this issue can happen suddenly.
There are other related problems, such as stains on the screen, freezing, flickering, going dark, or displaying colors, etc.
How to fix vertical or horizontal lines on the mobile phone screen
For this reason, we want to present you with different solutions so you can fix the vertical or horizontal lines on your phone. We bring some solutions that may be due to software or hardware issues of the phone.
Turn off and restart the phone
This is the quickest solution we can try to fix the lines that have suddenly appeared on the phone. To restart the phone, press and hold the power button for a few seconds until the restart option appears on the screen, or simply turn it off completely and turn it back on.
This is also a solution in case the tablet or phone does not turn on.
Check that the error is not coming from applications using safe mode
As mentioned earlier, the appearance of lines may be due to an application we have installed causing the issue. To fix this problem, in case it is due to an application error, start the device in safe mode.
Depending on your phone's brand, this process may be performed differently. You can do this, and once safe mode is initiated, check if the horizontal or vertical lines on the phone are still visible. This way, we can verify if the error is due to this.
Restore factory settings on the phone
This solution allows us to restore the phone to its original state, i.e., without the files or applications we have installed afterward.
Before doing anything, it is very important to back up everything we want to keep, especially photos or documents we have downloaded and stored in the device's memory. Depending on the phone's brand, the process will be carried out differently.
Solutions if the LCD line problem is hardware-related
In the previous section, we looked at different solutions to fix the lines on the phone if the problem comes from applications or the operating system.
It may happen that the lines still appear on the screen, so now we will look at solutions that will help if the issue comes from the phone's components.
Press the screen slightly and check connections
For a quick check, we can gently press between the screen and the back cover of the phone to test if the issue comes from a poor connection between the LCD and the flex cable connecting to the motherboard.
If the lines disappear, it can give us a good clue about where the problem might be. In this case, we need to disassemble the device and check those connections, and once done, see if it works correctly.
Replace the broken LCD screen with a spare
If the problem persists, it may be due to an LCD failure in the phone. The most advisable thing is to buy a complete replacement screen to replace the defective one that shows different colors. These screens integrate the LCD and touch functionality into a single piece.
The screen is broken or has gotten wet
This is one of the most common cases, and due to a fall, defects may have occurred, making it necessary to replace the screen with a spare one.
