Causes of Horizontal Lines on iPhone Screen

The most common causes of horizontal lines on iPhone screen include:

• Software glitches: Sometimes, temporary software glitches can cause the screen to malfunction and show lines.
• Faulty graphics card: Responsible for rendering images on the screen, a malfunctioning graphics card can cause horizontal lines.
• Overheating: Extended use or charging can cause the iPhone to overheat, which can also lead to screen issues.

Solutions to Fix Horizontal Lines on iPhone Screen
