Introduction
Lines on your phone screen can result from multiple causes, ranging from hardware damage to software glitches. Identifying the root cause is essential to determine the most effective solution, thereby saving time and reducing unnecessary repairs or costs.

Understanding the Problem: What Causes Screen Lines?
To address screen lines effectively, one must understand their causes. The source may be either hardware-related or software-induced, influencing the approach you’ll take to remedy the situation.
Types of Screen Lines
Screen lines can manifest in various forms:
1. Vertical lines

Identifying these variations assists in diagnosing the underlying issue more accurately.
Common Causes: Hardware vs. Software
Screen lines can arise due to:

Understanding whether your issue is hardware or software-related will direct the next steps.

Initial Troubleshooting Steps
Prior to engaging in repairs, simple troubleshooting steps might reveal a quick fix.
