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

The Nothing Phone (3a) brought Nothing’s distinctive styling into a more accessible device with a 120Hz AMOLED screen and a dedicated telephoto camera. It is also a phone where choosing protection is unusually visual: a bulky opaque case can hide much of the design. Here is how to protect it while keeping the character of the device.

1. Check the model before ordering

Phone (3a) and Phone (3a) Pro are not the same device. Before buying accessories:

1. Open Settings and then About phone.
2. Confirm the model is Phone (3a).
3. Do not rely on appearance alone—the camera hardware and body details differ from the Pro.

2. Nothing Phone (3a): the protection-relevant details

Phone (3a) uses a 6.77-inch FHD+ flexible AMOLED display with an adaptive refresh rate up to 120Hz and peak brightness up to 3000 nits. It is powered by Snapdragon 7s Gen 3 and includes a dedicated 50MP telephoto camera.

• 6.77-inch AMOLED display: Large enough that everyday pocket and bag scratches are worth planning for.
• 120Hz adaptive refresh: A good protector should preserve smooth touch response.
• 50MP OIS main + 50MP telephoto: The 2× optical telephoto adds a substantial rear camera assembly that benefits from case protection.
• 5000mAh battery and 50W charging: Designed for all-day use.
• IP64: Dust/splash resistance helps with environmental exposure, but not cosmetic wear.
• About 8.35mm and 201g: A flexible case can improve grip without making the phone feel excessively bulky.
• High-grade tempered glass and aluminium accents: Worth protecting if you want to preserve the original finish.

3. A sensible everyday protection setup

For most Phone (3a) owners, the simplest combination is a slim TPU case plus one screen protector. The case protects the sides, corners and rear camera area; the protector takes the scratches and scuffs on the display.

MEZON offers clear and black case finishes, so you can decide whether to show the transparent-inspired rear design or tone it down.

4. Clear TPU case

The clear MEZON case keeps the Phone (3a) design visible while adding a soft, grippy layer around the phone.

• transparent TPU;
• slim flexible construction;
• shock-absorbing edges for everyday knocks;
• precise model-specific cut-outs;
• wireless-charging-compatible case design.

A black TPU version is also available from the collection.

5. Screen protector choices for Phone (3a)

You can choose between three film types and two tempered-glass formats.

Ultra-clear film

The ultra-clear film is thin, glossy and unobtrusive—good if you mainly want scratch protection without changing the look of the screen.

Matte film

The anti-glare matte film reduces glare and fingerprints. It changes the screen finish slightly, so choose it for function rather than maximum gloss.

Hydrogel film

The hydrogel film is flexible and designed for close edge-to-edge coverage with minimal thickness.

Case-friendly tempered glass

The case-friendly tempered glass is a hard 9H option with extra perimeter clearance for cases.

Full-cover tempered glass

The full-cover tempered glass extends farther towards the edges if you prefer broader hard-glass coverage.

6. Film vs glass: which one makes more sense?

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

If you use a case with a particularly tight front lip, case-friendly glass or film is usually the easiest combination. If your priority is a hard glass feel, choose one of the tempered-glass options.

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.
