Part 1. Why Are There Lines on My iPhone Screen?

Some users reported that there are either vertical lines or horizontal lines on their iPhone screen. This issue occurs with iPhone 16, 15, 14, 13, 12, and 11 series in particular. In general, vertical or horizontal lines on your iPhone screen indicate a display or hardware issue. Here are some common causes:

• Loose or Damaged Display Cable: The screen connects to the motherboard through a display flex cable. If your iPhone has been dropped or pressed, this cable may become loose or damaged, leading to vertical or horizontal lines on the screen.
• Aging or Damaged Screen Components: The display panel's internal pixels or driver chips will degrade over time. Older iPhone models are more prone to screen discoloration, ghosting, or vertical line issues.
• System Glitches or Software Errors: Sometimes, the problem isn't hardware-related. A system update failure, cache conflict, or memory error can also cause display issues.
• Water Damage or Overheating: Exposure to moisture or excessive heat can damage the motherboard or display chip, resulting in vertical lines on the screen.
• High Brightness: Staying on the same screen at a high brightness may leave traces on your iPhone screen.
