Understanding and Resolving Small Black Horizontal Lines on Smartphone Screens

Experiencing visual anomalies on your smartphone screen can be concerning, especially when unexpected lines or color distortions appear. Recently, a user shared a common issue: upon returning to their device after carrying it in their bag, they noticed small black horizontal lines along with vertical streaks displaying various colors such as red, blue, green, magenta, pink, yellow, and white. This article aims to explore potential causes of such display issues and provide practical solutions to address them.

Common Causes of Screen Lines and Color Distortions

Several factors can lead to the appearance of horizontal lines or color anomalies on smartphone displays:

1. Physical Damage or Impact:
   If the device was subjected to pressure, accidental drops, or impact inside a bag, the physical integrity of the screen may be compromised, leading to dead pixels or damaged display connections.

2. Loose or Damaged Display Connections:
   Over time or due to impact, internal connectors between the display and the motherboard can become loose or damaged, resulting in visual artifacts.

3. Faulty or Malfunctioning Display Panel:
   Manufacturing defects, aging, or internal component failure can cause persistent lines or color distortions.

2. Check for External Damage:

3. Enter Safe Mode:
   Boot your device into safe mode to determine if third-party apps are causing the display problem. If lines are gone in safe mode, uninstall recently installed apps that might be causing conflicts.
