How To Fix a Broken iPhone Screen With Lines – Steps for 15, 14, XR, and 11 Displays
If your iPhone screen is showing vertical or horizontal lines—green, white, pink, or even flickering or blurry—it's possible to solve the problem at home without professional repair, especially for models like the iPhone 15, 14, XR, or 11. The two most common causes are software glitches or physical damage such as after a drop, which may result in a damaged, unresponsive, or cracked display. Here’s what you should do right away: begin by ruling out software issues with a forced restart and routine checks, then move step-by-step through physical connection issues or screen damage. This systematic approach will maximize your chances of fixing a frozen, glitching, or flickering iPhone screen with lines.
Check for Signs of Display Damage or Water Intrusion
Before troubleshooting software, inspect your screen for cracks, burnt spots, dim sections, or pink and green lines originating from a point of impact. As highlighted by iFixit, lines usually form around physical or water damage, so examine the corners, edges, and display surface for hairline cracks or color blotches.
If you recently dropped your device or noticed magnified, lifting, or popping out corners, shine a light at different angles to look for fine fractures. Use a paperclip to open the SIM tray and check the liquid contact indicator—if it’s pink or red, water may have seeped in, which often requires professional repair. Physical inspection provides an early clue whether further software solutions may even work.
Noticing unresponsive or blinking sections on the screen, or if the display is entirely black or blurred, also signifies potential cable or display damage underneath the glass. If the issue arose after a visible drop, this check is even more important. Damaged ribbons or loose connections can cause intermittent flickering or glitching in models like the iPhone XR, XS, 14, or even older devices like the 5S or 6s.
Restart and Force Reboot the iPhone
Sometimes, a frozen or glitching display with lines is due to a software crash, update error, or app malfunction. Performing a hard reset can often resolve these issues, as explained in this helpful YouTube guide. For iPhone 8 and newer:
- Quickly press Volume Up, then Volume Down.
- Hold the Side button until the Apple logo appears; then release.
For models like the 7 or 7 Plus, press and hold both the Volume Down and Side button simultaneously until you see the logo. If you have an iPhone 6s or SE (1st gen), hold down the Home and Top or Side button together. After a reboot, many users report vertical lines, dark spots, or magnified blurry text will often disappear if caused by a transient software hiccup.
If your screen remains unresponsive, dim, blue, or still displays the same lines after rebooting, you may be dealing with deeper hardware problems.
Update iOS and Check for App or System Bugs
Keeping your device updated reduces the chance of software-related glitches, display magnification, or touch input problems. Head to Settings > General > Software Update and ensure your iPhone XR, XS, 14, or 11 is running the latest iOS. Sometimes display glitches or color bands stem from operating system bugs or compatibility issues after a new app install.
If the lines or frozen sections only appear in a specific app—like FaceTime, iTunes, or Zoomed In mode—completely close and update those apps first. Persistent graphical errors across multiple screens, including lock-screen and timeout displays, are indicators of a system-wide problem, not just a bad app.
Updating iOS has successfully fixed flickering, dark, or green lines for many users, especially after a major iOS release. This is a completely free, no-risk step that could resolve unresponsive or glitching touch issues without replacing hardware (source).
If problems continue after updates and restarts, move on to physical troubleshooting or consult an expert.
Test for Loose Screen Connections and Apply Gentle Pressure
Occasionally, vertical or horizontal lines, magnified colors, or flickering are due to loose display connectors—especially after a drop or repair on models like the iPhone 5S, 7, XS, or XR. Gently, but firmly, try this method: press a clean finger directly along the line or fuzzy section, then slowly drag upward and downward. Some users have found this small adjustment can improve screen connections temporarily if the lines are due to a partial disconnect, as covered in the recommended troubleshooting video.
If you’re comfortable, reseat your screen connector. Open the device (only if your warranty is expired), and, using a non-metallic tool, detach and reattach the main display cable. Cleaning around the connector with compressed air or isopropyl alcohol can sometimes resolve persistent colored or blurry lines, especially if you see popping out or burnt spots after a hard drop (details).
If touch remains unresponsive or the problem worsens, seek professional repair instead of risking further display damage.
Use Apple Support and Professional Repair Services
If your iPhone display remains frozen, flickering, or shows lines after rebooting, updating, and connector checks, contact Apple Support through the official app or online. As advised in the guides above, you may still have warranty coverage, which could qualify you for a free or low-cost repair. Open the App Store, download the Apple Support app, and check for coverage or available service appointments.
If your phone is out of warranty, visit a certified repair center such as uBreakiFix by Asurion. Experts can quickly diagnose stubborn display, touch, and line issues that involve deep-seated physical or liquid damage and offer same-day repair for cracked, burnt, or dim displays on iPhone 14 and other models (see tips).
For persistent or worsening display problems—especially after drops resulting in dark, green, pink, or blurred stripes—replacement of the entire screen assembly may be recommended to restore your device to full working order.
Using these strategies, most causes of iPhone screen lines, flickers, and glitches can be identified and potentially resolved at home or through official support channels, so you can maximize the lifespan and reliability of your device.
