Causes of Blurry Horizontal Screen Lines
There are various factors that can lead to blurry horizontal screen lines on a phone. Here are some common causes to consider:
Issues with Screen Cable (Loose/ Damaged/ Intermittent)
When the screen cable is intermittent, loose, or damaged, or when the cable port is dusty, it can cause signal transmission issues from the motherboard to the screen. The screen may flicker and display horizontal or vertical lines intermittently.

LCD Display Malfunction on the Screen
LCD screens with faulty or improperly functioning pixels can result in horizontal or vertical lines on the screen. Depending on the severity of the screen damage, the appearance of these lines can vary.

Phone Affected by Magnetic Interference
Another possible cause of blurry horizontal lines on the screen is magnetic interference from the phone being exposed to high magnetic devices such as transmission stations, speakers, power sources, magnetic clips, etc. Aside from causing lines on the screen, magnetic interference can also result in internal component damage.

Phone Subjected to Physical Impact
During usage, unfortunate events such as frequent drops, strong collisions with hard objects, or being pressed by other heavy objects can lead to screen damage. This results in horizontal or vertical lines appearing on the screen or even the screen becoming unresponsive.

Phone Encounters Operating System Issues
In addition to user-related causes, software issues with the operating system can also lead to screen lines. Problems related to the operating system may include incomplete updates, app errors, software conflicts, etc.

Phone Infected with Viruses or Malicious Software
Accidentally downloading malicious software or being infected by viruses from files or apps can cause various phone errors, including blurry horizontal screen lines.
