S24 Ultra Screen Scratches: Anti-Reflective Coating Explained.
S24 Ultra Screen Scratches: Anti-Reflective Coating Explained – Ultimate Guide for Protection in 2025
Introduction to the Samsung S24 Ultra Display
The Samsung Galaxy S24 Ultra is Samsung’s most advanced flagship yet, boasting a Dynamic AMOLED 2X display with outstanding brightness, clarity, and contrast. One of its most discussed features in 2025 is the anti-reflective (AR) coating applied to the glass.
While Samsung markets it as a major step forward in sunlight visibility and color accuracy, many users have noticed that this same coating can be susceptible to visible scratches—sometimes even when the phone hasn’t been dropped.
At Sydney CBD Repair Centre, we’ve repaired countless flagship devices, and we’ve seen firsthand how micro-scratches and coating wear can impact your premium screen. If you’ve invested in a top-tier phone like the S24 Ultra, understanding how the AR coating works—and how to protect it—is crucial.
What is the Anti-Reflective Coating on the S24 Ultra?
The anti-reflective coating is a thin, transparent layer applied over the Gorilla Glass Armor to reduce glare, especially under bright sunlight.
How It Works
The coating changes how light interacts with the surface:
- It reduces specular reflection (the blinding mirror-like glare) by manipulating the refractive index.
- It enhances screen readability in direct sunlight.
- It improves perceived contrast, making colors pop without over-saturating them digitally.
Benefits Beyond Glare Reduction
The AR layer also:
- Minimizes fingerprint visibility.
- Makes dark mode look deeper and richer.
- Reduces eye strain when using the phone outdoors.
But there’s a trade-off—this layer is softer than the glass beneath it, meaning scratches can appear without the glass actually breaking.
Why the S24 Ultra is Prone to Screen Scratches
Gorilla Glass Armor vs Real-World Usage
Corning’s Gorilla Glass Armor is extremely tough against drops, but scratch resistance is a different battle. The AR coating can be marked by hard dust particles, sand, or even metal fragments from keys and coins.
How Micro-Scratches Happen
The AR coating is measured in microns—thinner than a strand of hair. Even a small abrasive particle in your pocket can leave visible scuffs if pressed against the screen.
This is why some users report scratches within weeks of ownership despite being careful.
The Role of Anti-Reflective Coating in Scratch Visibility
Light Diffusion and Scratch Perception
Interestingly, scratches are more visible on AR-coated glass because the coating alters light refraction. Even shallow marks can catch light differently, making them look deeper than they are.
Coating Degradation Over Time
With regular use, the AR layer can wear unevenly, leading to “patchy” spots where glare returns. This is not necessarily glass damage—it’s coating removal.
Common Causes of S24 Ultra Screen Scratches
- Pocket Grit and Dust – Tiny quartz particles in dust are harder than glass.
- Charging in the Car – Vibration plus loose objects = micro-abrasion.
- Accidental Drops – Even a short fall onto a textured surface can leave marks.
Testing the Durability of the Anti-Reflective Layer
Laboratory Scratch Tests
Mohs hardness tests suggest Gorilla Glass Armor is around level 6 on the Mohs scale—but AR coatings can be softer, closer to level 3–4.
Real-World Consumer Reports
Tech forums and YouTube reviews confirm that while the glass remains intact, cosmetic wear is a recurring theme for AR-coated flagships.
How to Protect the S24 Ultra Anti-Reflective Coating
Best Screen Protectors for 2025
- Premium tempered glass with oleophobic coating.
- Nano-coating protectors that mimic AR benefits.
Cleaning Practices to Prevent Damage
- Use a microfiber cloth only.
- Avoid paper towels or rough fabrics.
- Don’t use abrasive cleaning sprays—mild water or phone-safe cleaners work best.
Repairing or Replacing a Damaged Coating
Can It Be Restored?
The AR layer cannot be reapplied at home—it requires factory-level equipment.
When a Full Screen Replacement is Needed
If scratches interfere with visibility or the coating is mostly gone, replacing the full screen (with a new AR layer) is the only long-term fix.
At Sydney CBD Repair Centre, we use genuine Samsung parts, ensuring your display looks and feels brand new.
Myths About Screen Scratches and Coatings
“It’s Just Cosmetic” – Why That’s Misleading
While small scratches won’t stop the phone from working, they reduce resale value and can worsen over time.
“Coating Damage Means the Glass is Weak” – The Truth
The glass itself can still be strong—the coating’s weakness doesn’t mean the structure is compromised.

FAQs
Q1: Does the S24 Ultra scratch more easily than older models?
A: The AR coating can scratch more easily, but the glass strength is still improved.
Q2: Can I polish out AR coating scratches?
A: No—polishing removes more coating and can worsen glare.
Q3: Is a screen protector worth it if the phone already has Gorilla Glass Armor?
A: Yes, especially to protect the AR coating from visible wear.
Q4: How long does the AR coating last?
A: With care, it can last years, but heavy use may show wear within months.
Q5: Will Samsung warranty cover coating scratches?
A: Generally, no—cosmetic damage is not covered.
Q6: Can professional repair shops fix the AR layer without replacing the screen?
A: Not reliably—the correct fix is replacing the full display assembly.
Conclusion
The Samsung Galaxy S24 Ultra’s anti-reflective coating is a technological upgrade that dramatically improves outdoor visibility—but it comes with a trade-off in scratch resistance.
By understanding how it works, what causes scratches, and how to protect it, you can extend the life and beauty of your screen.
If your S24 Ultra screen is already scratched or the coating is wearing off, Sydney CBD Repair Centre offers genuine Samsung screen replacements done by expert technicians—same-day repairs with a 90-day warranty.
