iPhone 18 Pro Problems: 7 Known Issues & How to Fix Them

Updated October 2026

Quick answer: Most early iPhone 18 Pro problems are already fixed. Update to the latest iOS (Settings > General > Software Update) to fix the Face ID restart bug, a camera color glitch, and a frozen touchscreen issue. Two problems still need attention: AT&T signal loss on some Pro Max models, which needs a free replacement if it has already happened, and speaker crackling, which has no official fix yet.

Before Anything Else: Update Your iPhone

Most of these problems were fixed by software updates, so this is the first thing to try.

  1. Open Settings.
  2. Tap General, then Software Update.
  3. Tap Update Now if an update is available.

Make sure you’re on iOS 27.0.1 or later. iOS 27.1, released in October, is the newest version.

1. Face ID Freezes and Restarts the iPhone

The problem: When Face ID failed to recognize you, especially when opening a locked app, the iPhone could freeze and then restart to the lock screen.

Status: Fixed ✅ Apple fixed this in iOS 27.0.1, released on September 28, 2026.

What to do: Update to the latest iOS. If Face ID still fails after updating:

  1. Go to Settings > Face ID & Passcode.
  2. Tap Reset Face ID, then set it up again.
  3. Make sure nothing is covering the top of the screen, like a thick screen protector.

2. iPhone 18 Pro Max Losing Signal on AT&T

The problem: A small number of iPhone 18 Pro Max owners on AT&T in the US lost cellular service completely. Their phones got stuck on “SOS” and couldn’t make calls, send texts, or call 911. Restarting didn’t help.

Who’s affected: Only the iPhone 18 Pro Max on AT&T. Apple says the regular iPhone 18 Pro, other carriers, and other models aren’t affected.

Status: Partly fixed ⚠️ iOS 27.0.1 plus an AT&T carrier settings update prevents the problem. But if your phone has already lost service, a software update won’t bring it back. Apple is replacing affected phones.

What to do:

  • If your phone works fine: Update to the latest iOS now. Then go to Settings > General > About and wait a few seconds. If a “Carrier Settings Update” pop-up appears, tap Update.
  • If you’ve already lost service: Contact Apple Support or AT&T, or visit an Apple Store or AT&T store to get a free replacement.

3. Speaker Crackling or Popping

The problem: Some owners hear a faint crackle, pop, or clicking sound, mostly from the earpiece speaker at the top of the phone. It can happen during calls or while just scrolling.

Status: No fix yet ❌ iOS 27.0.1 didn’t fix it, and Apple hasn’t confirmed the cause. Some people who swapped their phone say the replacement had the same noise, which suggests it may be a software bug that a future update could fix.

What to do:

  1. Update to the latest iOS, in case a newer version has improved it.
  2. Restart your iPhone.
  3. Take off your case and any MagSafe accessories, then test again.
  4. Check that the speaker grille isn’t blocked by dust or a screen protector.
  5. If the noise is loud or makes calls hard to hear, contact Apple while you’re still inside your return window (usually 14 days from purchase in the US).

Tip: Record a short screen recording with sound when the crackling happens. It makes it much easier to show Apple Support. See How to Screen Record on iPhone.

4. Color Glitch in 2x Photos

The problem: On a small number of iPhone 18 Pro models, photos taken at 2x zoom at the f/1.48 aperture could show a strange color artifact in certain lighting.

Status: Fixed ✅ Apple fixed this in iOS 27.0.1. Update your iPhone and take a new test photo at 2x.

5. Touchscreen Freezes When Opening Control Center

The problem: Opening Notification Center and Control Center at the same time could make the screen stop responding. This affected all iPhones running iOS 27, not just the 18 Pro.

Status: Fixed ✅ Fixed in iOS 27.0.1.

If your screen is frozen right now, force restart your iPhone:

  1. Press and release Volume Up.
  2. Press and release Volume Down.
  3. Press and hold the Side button until the Apple logo appears.

6. Green or Pink Line on the Screen

The problem: In the first week after launch, videos spread online showing a green or pink line across the iPhone 18 Pro display.

Status: Unconfirmed ❓ Apple hasn’t confirmed the problem, and people pointed out that some of the viral videos didn’t look genuine.

What to do: If you actually see a line on your screen:

  1. Restart your iPhone.
  2. Take a screenshot while the line is visible. If the line doesn’t appear in the screenshot, it’s a hardware display problem, not software.
  3. If it’s still there after restarting, contact Apple. A new iPhone is covered by warranty.

7. Magnets and the Variable Aperture Camera

The problem: The iPhone 18 Pro’s main camera uses six tiny blades for its new variable aperture. In iFixit’s teardown, a strong magnet held right next to the camera could move those blades, which made some people worry about MagSafe accessories.

Status: Not a real-world problem so far ❓ The tests were done with strong magnets held close to the camera, not with normal MagSafe chargers or cases.

What to do: If your photos suddenly look blurry or too dark:

  1. Remove any magnetic accessory near the camera, like a magnetic grip, mount, or wallet.
  2. Take the photo again.
  3. Stick to MagSafe-certified accessories, which attach to the center ring, away from the camera.

Other Reports

Some owners on Reddit have also reported the phone’s color fading or changing over time, and a few mentioned paint chipping on the frame. These reports are limited, and Apple hasn’t commented. If your phone looks damaged within weeks, take photos and contact Apple.

Should You Still Buy the iPhone 18 Pro?

Yes. The most serious problem, Face ID restarts, is already fixed, and the AT&T issue is now prevented by the latest update. The only open issue is speaker crackling, and it doesn’t affect every phone.

If you buy one, update it to the latest iOS right away, and test the speaker and Face ID within your return window.
