Even though the iPhone SE is compact and powerful, some users have reported display issues like screen flickering, gray lines, or random color screens (blue or red). The good news? Many of these problems are software-related—and often fixable at home.

Here’s a full guide to help you troubleshoot and fix iPhone SE display problems.

What Causes iPhone SE Screen Issues?

• Corrupted apps or program crashes (like the Camera or FaceTime)
• Bugs from recent iOS updates
• Memory problems (low storage space, sluggish performance)
• Hardware damage (drops or water exposure)
