What Is the Pink Line on iPhone Screens?
The pink line issue typically shows up as:
- A single vertical pink or purple line
- Running from the top to the bottom of the screen
- Often located along the right or left side
- Sometimes faint, other times bold and persistent
It may appear suddenly, with no drop or water damage involved. For many, it seems to happen overnight, after a software update, or during regular use.
The pink line doesn’t just impact the look of your display — it can be a red flag that something’s wrong under the surface.
Why Is There a Pink Line on My iPhone?
Let’s dive into the most common causes behind this frustrating problem.
1. Software Glitches
Sometimes, the pink line is caused by a temporary bug in the iOS operating system. If a graphical rendering error occurs (especially after an update), your iPhone may incorrectly display colors or lines.
Fix: A simple restart or iOS update may resolve it.
2. Defective Display Panel
The most common root cause is a hardware problem — particularly with the OLED screen. Internal connectors may be loose, or the display itself could be faulty from the factory.
Fix: Requires screen replacement or phone repair.
3. Display Connector Damage
If your phone has been dropped or bent, even slightly, the display cable or internal components could have been affected.
Fix: Reconnecting or replacing the cable inside the device (done by a technician).
4. Overheating or Internal Pressure
Excess heat or consistent pressure (like sitting on your phone in your pocket) can warp the internal layers of the screen.
Fix: In severe cases, only a screen replacement works.
5. iOS Update Conflicts
Some users report the pink line appearing immediately after updating their iPhone to the latest iOS version. Although rare, new software can sometimes trigger rendering issues.
Fix: A future update might fix it, or you may need a rollback via iTunes.
Affected iPhone Models
While the problem has popped up across multiple iPhone generations, it’s most commonly reported in:
- iPhone 13 and iPhone 13 Pro
- iPhone 12 models (less frequent)
- iPhone X and XS series
Newer iPhones like the iPhone 14 and 15 haven’t shown the issue as widely, suggesting Apple may have made hardware improvements.
Troubleshooting the Pink Line Issue
Here are some steps you can take before heading to a repair shop:
✅ Step 1: Restart Your iPhone
This might sound basic, but restarting your phone can reset the graphics system.
- Press and hold the side button + volume button
- Slide to power off
- Wait 10 seconds, then turn it back on
✅ Step 2: Check for iOS Updates
Go to Settings > General > Software Update. If an update is available, install it. Apple may fix display bugs silently through patches.
✅ Step 3: Reset All Settings
This won’t erase your data but will reset system settings.
- Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings
✅ Step 4: Backup and Factory Reset
As a last resort, try erasing your iPhone and starting fresh.
- Backup your data first via iCloud or iTunes
- Go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings
If the pink line returns even on a clean system, the issue is most likely hardware-based.
When to Contact Apple Support
If none of the DIY steps work, it’s time to let the pros handle it.
🛠️ What Apple Will Do:
- Run a full diagnostic test to check for display failures
- If under warranty or AppleCare+, they may offer a free screen replacement
- In rare cases, you may be eligible for a device replacement
💰 Out of Warranty?
Expect to pay around:
- $279–$329 USD for screen repair (varies by region)
- Local third-party repair shops may charge less but can void Apple warranty
Apple has not acknowledged this as a widespread design flaw, so free repairs are typically limited to valid coverage situations.
Real-World Cases
Here are a few real user experiences that help illustrate the situation:
📱 Meena from Singapore:
“I updated my iPhone 13 Pro to iOS 17, and the pink line showed up the next day. Apple replaced the screen for free under warranty. They said it was a display connector issue.”
📱 Carlos from Texas:
“Mine started after I dropped it lightly. No cracks, but that pink line wouldn’t go. Apple quoted $300 for repair, so I went to a local shop instead. It’s fixed now, but Face ID no longer works.”
These stories highlight why quick diagnosis and smart repair choices are important.
How to Avoid the Pink Line Problem
Once your device is fixed — or if you haven’t experienced the issue yet — it’s worth following a few habits to prevent display damage:
- Use a high-quality case and screen protector
- Avoid putting your phone in tight pockets or under pressure
- Don’t expose your phone to extreme heat
- Always update iOS from a stable Wi-Fi connection (avoid interruptions)
- Get regular battery and hardware health checks at the Apple Store

Is It Worth Fixing or Should You Upgrade?
If the pink line is just a cosmetic issue (not affecting touch response), you might consider living with it. But if it’s spreading, flickering, or affecting your usage, repair is usually worth it — especially if under warranty.
If your device is out of warranty and the repair cost is high, it might be better to:
- Trade in your iPhone for credit toward a new one
- Sell it as-is and upgrade to a newer model
Always compare the cost of repair vs value of a new phone — especially since newer iPhones now have better screen durability and fewer display issues.
Final Answer: Why Is There a Pink Line on My iPhone?
To summarize, the pink line on your iPhone screen could be due to:
- A defective OLED display
- A loose or damaged screen connector
- A software glitch, especially post-update
- Physical or heat damage that affected internal components
Start with simple fixes like restarting or updating iOS, and escalate to Apple support if the issue persists. In many cases, the repair is straightforward and might be free if you’re under warranty.
Remember, iPhones are delicate — especially their screens. Handle with care, keep your device updated, and don’t ignore small display changes that could signal bigger problems.
Bonus: What to Ask at the Apple Store
If you’re going in for service, ask:
- “Is this a known issue for my model?”
- “Can this be repaired under warranty?”
- “Will Face ID or other features be affected?”
- “Can I get a screen replacement only, or does the whole unit need replacement?”
Knowing what to expect helps you avoid surprise costs and make the best decision.
