OPPO A57s Accessories Guide: Screen Protectors Compared

Using an OPPO A57s and deciding how to protect it? This guide follows the same practical structure as our other OPPO accessory articles: confirm the exact model, understand what makes the phone distinctive, compare every currently listed MEZON accessory, and choose the protection style that suits how you actually use the device.

1. Make sure you have the right OPPO A57s

Check the phone name in Settings > About phone before ordering. The A57 and A57s are closely related but should still be matched to the exact listing. Check Settings > About phone before ordering.

2. OPPO A57s at a glance

The OPPO A57s kept the battery-and-audio strengths of the A57 but upgraded the camera system. Its 50MP main camera is paired with a 5,000mAh battery, 33W SUPERVOOC, stereo speakers and a slim 7.99mm body. That makes it a more camera-focused take on the same practical A-series formula.

Display	6.56-inch HD+ LCD, 1612 × 720, 60Hz
Processor	MediaTek Helio G35
Memory & storage	4GB RAM + 128GB storage on the Australian specification
Battery	5,000mAh with 33W SUPERVOOC
Rear camera	50MP main + 2MP mono camera
Design	Approximately 7.99mm thick and 187g

What is especially interesting about this phone?

• The 50MP main camera is the clearest hardware upgrade over the standard A57.
• OPPO's Ultra-Linear Stereo Speaker system adds a stronger entertainment focus than a single-speaker budget phone.
• The body remains under 8mm thick despite the 5,000mAh battery.
• NFC support on the Australian model makes contactless payments practical.

3. Why protection makes sense on the OPPO A57s

The display is one of the largest exposed surfaces on a smartphone. Pocket grit, keys, bags, desk contact and accidental knocks can all leave permanent marks. A model-specific protector adds a replaceable layer over the front glass.

The current MEZON collection contains 5 live accessory options. This guide only includes products actually listed in the collection rather than mentioning accessories that are not sold for this model.

Fingerprint note: this model does not rely on an under-screen optical sensor, so the protector itself does not cover the main fingerprint-reader hardware.

4. Current MEZON accessories for OPPO A57s

4.1. Ultra Clear TPU Film

[3 Pack] MEZON OPPO A57s Ultra Clear TPU Film

A thin transparent TPU film for everyday scratch, scraping and abrasion protection while keeping the screen close to its original glossy appearance.

Who it suits: Best for maximum display clarity, a smooth touch feel and minimal added thickness.

Protection focus: clear TPU film is mainly for scratches and surface wear. It stays thinner than glass but does not provide the same rigid impact protection.

4.2. Case-Friendly 9H Tempered Glass

[2 Pack] MEZON OPPO A57s Case-Friendly 9H Tempered Glass

Hard 9H tempered glass designed for stronger scratch and front-impact protection, with deliberate perimeter clearance to work more comfortably with many phone cases.

Who it suits: Best for harder front protection when you also use a phone case.

Why the edge gap? Case-friendly glass intentionally leaves perimeter clearance so many phone cases are less likely to catch and lift the protector.

4.3. Clear Edge-to-Edge Hydrogel Film

[3 Pack] MEZON OPPO A57s Clear Edge-to-Edge Hydrogel Film

A flexible Hydrogel protector designed for fuller edge-to-edge surface coverage while remaining thin and soft rather than rigid like glass.

Who it suits: Best for flexible fuller coverage and users who prefer film rather than a rigid glass protector.

Protection focus: Hydrogel is flexible film. Its advantage is fuller flexible coverage, not the rigid impact barrier of tempered glass.

4.4. Anti-Glare Matte TPU Film

[3 Pack] MEZON OPPO A57s Anti-Glare Matte TPU Film

A lightly textured TPU film that helps reduce reflections, glare, fingerprints and smudges. The matte finish deliberately diffuses light, so it looks less glossy than Clear film.

Who it suits: Best for bright environments, reading and users who dislike visible fingerprints.

Trade-off: matte reduces glare by diffusing light, so the display can look slightly softer than it does through glossy Clear film.

4.5. Full-Cover 9H Tempered Glass

[2 Pack] MEZON OPPO A57s Full-Cover 9H Tempered Glass

A fuller-coverage tempered-glass design that extends further towards the front edges for a more edge-to-edge appearance.

Who it suits: Best for broader glass coverage and users who prefer a more finished edge-to-edge front appearance.

Case fit: full-cover glass reaches further towards the edges, so very tight cases should be checked after installation to ensure they do not press underneath the glass border.

5. Which option should you choose?

The best choice depends on what you want to protect and how you want the screen to feel. Flexible film prioritises thinness, Matte prioritises glare control, Hydrogel offers fuller flexible coverage, tempered glass provides a harder surface, and a gel case protects the body rather than the display.

Option	Protection focus	Finish	Fit / coverage
Ultra Clear TPU Film	Scratch / abrasion	Glossy transparent film	Thin and case-friendly
Case-Friendly 9H Tempered Glass	Harder scratch / impact	Clear 9H glass	Extra case clearance
Clear Edge-to-Edge Hydrogel Film	Scratch / surface wear	Flexible clear Hydrogel	Fuller edge-to-edge film
Anti-Glare Matte TPU Film	Scratch / abrasion	Anti-glare matte film	Thin and case-friendly
Full-Cover 9H Tempered Glass	Harder scratch / impact	Full-cover 9H glass	Broader front coverage

6. Recommended setups

• Maximum screen clarity: Ultra Clear film keeps the display closest to its original glossy appearance.
• Reduced glare and fingerprints: Matte film is the strongest choice for bright rooms and a less reflective surface.
• Flexible fuller coverage: Hydrogel reaches closer to the display edges while remaining soft and thin.
• Glass plus a phone case: case-friendly 9H glass gives harder protection while leaving useful perimeter clearance.
• Broader glass coverage: full-cover 9H glass suits users who prefer a more edge-to-edge glass appearance.

7. Installation tips and common mistakes to avoid

7.1. Before installation

• Wash and dry your hands and work on a clean table away from fans and open windows.
• Turn the display off so fingerprints, dust and alignment are easier to see.
• Clean the screen thoroughly and remove the final dust particles before exposing adhesive.
• Do a dry alignment first and check the front camera, earpiece and edge position.

7.2. TPU film and Hydrogel

• Apply progressively rather than dropping the entire protector onto the display at once.
• Push air gently towards the nearest edge and avoid sharp tools.
• Remember that flexible film is mainly for surface wear; it does not feel or behave like rigid glass.

7.3. Tempered glass

• Once alignment is correct, lower the glass gently and allow the adhesive to spread naturally.
• The visible edge gap on case-friendly glass is intentional and helps with case clearance.
• With full-cover glass, check that your phone case does not press underneath the glass border.

9. FAQ: OPPO A57s protection

Is tempered glass better than film?

Tempered glass is generally the stronger option when hardness and front-impact protection are your priorities. TPU and Hydrogel films are thinner and more flexible, making them better when minimum bulk, a matte finish or fuller flexible coverage matters more.

What is the difference between case-friendly and full-cover glass?

Case-friendly glass leaves extra clearance around the perimeter so many phone cases are less likely to catch it. Full-cover glass extends further towards the front edges for broader visual coverage.

Does Matte film reduce clarity?

Matte film deliberately diffuses reflected light. That helps reduce glare and makes fingerprints less visible, but the screen can look slightly softer than it does through glossy Clear film.

What is Hydrogel?

Hydrogel is a soft, flexible screen-protector material. It is useful for scratches and surface wear and can provide fuller flexible coverage, but it should not be treated as equivalent to tempered glass for direct impact resistance.

Can I use an accessory for a similar OPPO model?

No. Use an accessory specifically listed for the OPPO A57s. Similar OPPO names can still hide important differences in dimensions and front-camera layout.
