Nothing Phone (3a) Pro Cases & Screen Protectors: Complete Guide

The Nothing Phone (3a) Pro is visually distinctive even by Nothing standards, with a prominent circular camera system and transparent-inspired rear design. Protection therefore has two jobs: keep the screen and camera area safe while preserving the look of the phone. MEZON currently offers seven model-specific options across cases, films and tempered glass.

1. Phone (3a) Pro is not the same as Phone (3a)

The Pro model has a different camera arrangement and should use its own accessories.

1. Open Settings → About phone.
2. Confirm the device name says Phone (3a) Pro.
3. Only then choose accessories labelled for the Pro model.

2. The key Phone (3a) Pro features to protect

Phone (3a) Pro uses Nothing’s 6.77-inch FHD+ flexible AMOLED platform with an adaptive 120Hz refresh rate and up to 3000 nits peak brightness. Its defining hardware difference is the camera system, including a 50MP periscope telephoto camera with 3× optical zoom.

• 6.77-inch AMOLED: Large, bright and central to the user experience.
• 120Hz adaptive refresh: Smooth input makes touch performance important after installing a protector.
• 50MP periscope telephoto: 3× optical zoom plus in-sensor and digital zoom give the Pro a substantial rear camera system.
• Snapdragon 7s Gen 3: Designed for responsive 5G everyday performance.
• 5000mAh battery: Built for long daily use.
• IP64 protection: Useful against dust and splashes, but unrelated to scratches and impact wear.

3. Prioritise the camera area as well as the screen

On the 3a Pro, the rear camera module is more visually and physically prominent than on the standard 3a. A case with a properly shaped camera opening is therefore especially valuable.

MEZON lists both clear and black slim TPU cases. Clear is the obvious choice if you want the design to remain visible; black gives the phone a more restrained appearance.

4. Clear TPU case

The clear option wraps the sides and back in flexible TPU while leaving the distinctive rear design visible.

• slim transparent construction;
• extra grip around the sides;
• shock absorption for normal knocks;
• precise camera and control cut-outs;
• wireless-charging-compatible case design.

The black TPU case is available alongside it in the MEZON Phone (3a) Pro collection.

5. Screen protector options

The five screen protector choices let you prioritise clarity, glare reduction, flexibility, case clearance or harder glass protection.

Ultra-clear film

Ultra-clear film is the simplest transparent film option and keeps the original glossy look of the display.

Matte film

Matte film reduces glare and makes fingerprints less obvious—useful if you often use the phone under bright lights.

Hydrogel film

Hydrogel film is thin and flexible, with close coverage and strong compatibility with cases.

Case-friendly tempered glass

Case-friendly tempered glass gives you the harder feel of 9H glass while deliberately leaving more room around the display edge.

Full-cover tempered glass

Full-cover tempered glass is designed for users who want the most extensive hard-glass coverage across the front.

6. How to choose

Protector	Main advantage	Best for
Ultra-clear film	Very thin with a glossy transparent finish	Users who want a simple film layer with minimal visual change
Matte film	Reduces reflections and visible fingerprints	Bright environments and users who prefer a less glossy screen
Hydrogel film	Flexible, close-fitting and edge-to-edge	Minimal thickness and easy case compatibility
Case-friendly tempered glass	Hard 9H glass with extra perimeter clearance	Tightly fitted cases
Full-cover tempered glass	Broader hard-glass coverage	Users who prefer a rigid glass feel and more edge coverage

A useful rule is: film for minimal thickness, glass for a harder feel. Within those groups, choose matte for glare reduction or case-friendly glass if your case fits tightly around the display.

7. Installation tips for a cleaner result

Even the best protector can look disappointing if dust or poor alignment gets underneath it. A few extra minutes of preparation usually make the biggest difference.

• Wash and dry your hands before starting.
• Work on a clean, stable surface away from open windows and fans.
• Clean the display thoroughly with the supplied cleaning materials.
• Use the dust-removal sticker to pick up any remaining particles.
• Check the top, bottom and camera/sensor alignment before applying the protector fully.
• For film protectors, apply progressively rather than pressing the whole surface down at once.
• For tempered glass, do a dry alignment check first and lower the glass evenly onto the screen.
• Avoid repeatedly lifting and reapplying the protector, as this can introduce dust and reduce adhesion.
• After installation, test fingerprint unlocking. If recognition is less consistent, re-register your fingerprint with the protector fitted.
• If you also use a case, fit the protector first and then check that the case edge does not push against it.

8. Recommended combinations

For maximum visual impact: clear TPU case + ultra-clear or hydrogel film.

For reduced glare: clear or black TPU case + matte film.

For a hard screen surface: TPU case + case-friendly tempered glass.

For broader glass coverage: full-cover tempered glass, provided your chosen case leaves sufficient edge clearance.

	Clear TPU Gel Case Protects the camera and body while leaving Nothing’s rear design visible.
	3-Pack Hydrogel Film Flexible and low-profile for a nearly bare-screen feel.
	2-Pack Case-Friendly Tempered Glass Our practical hard-glass choice if you also use a case.

9. FAQ: Nothing Phone (3a) Pro accessories

Can Phone (3a) screen protectors fit the Pro?

Do not assume they will. Buy a protector specifically labelled for Phone (3a) Pro.

Why is camera protection especially important on the Pro?

The Pro uses a more substantial periscope camera system. A model-specific case helps keep that camera area away from direct contact with hard surfaces.

What is the least bulky screen protector?

Ultra-clear film and hydrogel are both very thin. Hydrogel is the more flexible edge-to-edge option.

Which option is best for glare?

Matte film is specifically designed to reduce reflections and visible fingerprints.

Which tempered glass is best with a case?

Case-friendly tempered glass gives you the most deliberate clearance around the perimeter.
