HONOR 400 Pro 5G Cases & Screen Protectors: Complete Guide

Picked up an HONOR 400 Pro 5G and want to keep its large display, slim frame and camera system protected? In this 2026 guide, we’ll help you confirm the exact model, explain which parts of the phone are most worth protecting, and look at the screen protection currently available from MEZON.

1. Make sure you have the right HONOR 400 Pro 5G model

Before ordering any case or screen protector, confirm the exact phone model. Accessories that look almost identical can still differ in screen dimensions, edge shape, camera cut-outs and button placement.

To check your HONOR model:

1. Open Settings.
2. Open About phone.
3. Check the device name and model information.
4. Confirm that your phone is the HONOR 400 Pro. MEZON uses the name HONOR 400 Pro 5G in accessory listings to make the 5G model clear.

If that matches your phone, the fit guidance in this article applies to your device.

2. HONOR 400 Pro 5G at a glance

The HONOR 400 Pro combines a premium display and camera system with a relatively slim body. HONOR lists a 200MP main camera, 50MP telephoto camera, 6000mAh silicon-carbon battery, Snapdragon 8 Gen 3 processor and IP68/IP69 water and dust resistance.

Key details that matter when choosing protection:

• High-resolution display: The screen runs at 2800 × 1280 resolution with up to a 120Hz refresh rate, so keeping the front surface free from scratches helps preserve one of the phone’s most important features.
• Bright panel: HONOR advertises up to 5000 nits HDR peak brightness, making clarity especially important if you use the phone outdoors.
• Large camera system: The 200MP main camera and 50MP telephoto camera create a prominent camera area that benefits from a case with a raised protective edge.
• Slim but substantial: HONOR lists the phone at around 8.1mm thick and approximately 205g, so extra grip can make everyday handling more secure.
• Fast wired and wireless charging: The phone supports 100W wired and 50W wireless HONOR SuperCharge, so a case should fit properly around the charging area and not add unnecessary thickness.
• Built-in durability: IP68/IP69 resistance and reinforced construction are useful, but they do not prevent cosmetic scratches, chipped edges or damage from every drop.

3. Why a case and screen protector still matter

Durability ratings are helpful, but everyday wear tends to come from smaller incidents: grit in a pocket, keys in a bag, sliding the phone across a desk, or dropping it onto a hard floor.

Screen protection
A screen protector creates a replaceable surface layer between the original display and scratches, scuffs or direct contact.

Corner and edge protection
A well-fitted case can help absorb some energy from knocks and drops while also protecting the side frame from chips and marks.

Camera protection
Because the camera housing is prominent, look for a case with a raised lip around the camera area so the lenses are less likely to rest directly on hard surfaces.

Grip
A slim phone with smooth surfaces can be slippery. Even a lightweight flexible case can make one-handed use feel more secure.

4. Choosing a case for HONOR 400 Pro 5G

At the time of writing, MEZON’s live collection for this model currently lists a hydrogel screen protector rather than a case. If you are choosing a case elsewhere—or if more case options are added later—focus on fit rather than appearance alone.

Useful features to look for include:

• Exact model fit: The camera opening, flash, buttons and charging port should line up precisely.
• Raised screen edge: A small lip around the front can help reduce direct screen contact when the phone is placed face-down.
• Raised camera edge: This is particularly useful on a phone with a large camera module.
• Flexible shock-absorbing sides: TPU-style materials can add grip and cushioning without making the phone overly bulky.
• Wireless charging compatibility: Avoid unnecessarily thick or metal-backed cases if you want to use the phone’s wireless charging capability.

5. Screen protector options for HONOR 400 Pro 5G

There are several common screen protector materials on the market. The best choice depends on whether you prioritise flexibility, impact resistance, glare reduction or a glass-like feel.

• Hydrogel film: Very thin and flexible, with close edge coverage and a softer surface.
• Tempered glass: Harder and thicker, usually preferred by users who want stronger scratch resistance and a glass-like feel.
• Matte film: Reduces reflections and fingerprints, but slightly changes the visual finish of the screen.

MEZON currently lists a clear hydrogel option for this model.

5.1. MEZON clear hydrogel film

The current MEZON protector is a 3-pack clear hydrogel film designed specifically for the HONOR 400 Pro 5G.

• Edge-to-edge coverage: Designed to cover the screen closely from edge to edge.
• Ultra-clear finish: Intended to preserve display clarity and colour.
• Fingerprint-sensor compatible: The product is listed as compatible with the phone’s fingerprint sensor.
• Case friendly: Its thin construction is designed to work with cases more easily than many thick glass protectors.
• Flexible protection: A good option for everyday scratches, scuffs and users who prefer minimal extra thickness.

6. Hydrogel film vs tempered glass

Feature	Hydrogel film	Tempered glass
Thickness	Very thin	Thicker
Feel	Flexible film	Hard glass-like surface
Scratch protection	Good for everyday marks	Usually stronger against hard scratches
Edge coverage	Well suited to close edge coverage	Depends on glass design
Case compatibility	Typically very good	Depends on thickness and edge shape

If you dislike extra thickness and want a flexible protector that works neatly with a case, hydrogel is a practical choice. If you prefer a harder, more glass-like surface, tempered glass may suit you better when a compatible option is available.

7. Installation tips

Good installation matters just as much as the protector material. Dust trapped under the film can create visible bumps, while poor alignment can cause lifting around the edges.

• Wash and dry your hands before starting.
• Work in a clean area away from open windows, fans and floating dust.
• Clean the screen thoroughly and remove every visible dust particle.
• Check the protector orientation before exposing the adhesive surface.
• Align the film carefully with the screen edges and sensor/camera areas.
• Use the installation card to smooth the film progressively across the display.
• Push larger air bubbles towards the nearest edge rather than repeatedly lifting the protector.
• After installation, check touch response and fingerprint unlocking.

9. FAQ: HONOR 400 Pro 5G cases & screen protectors

Is HONOR 400 Pro the same as HONOR 400 Pro 5G?

HONOR’s official Australian product name is HONOR 400 Pro. MEZON uses HONOR 400 Pro 5G in accessory listings to make the model’s 5G connectivity clear.

Does the HONOR 400 Pro need a screen protector?

A screen protector is optional, but it adds a replaceable layer against everyday scratches and scuffs. That can be worthwhile on a high-resolution display that you use every day.

Will hydrogel film work with a case?

The current MEZON hydrogel protector is specifically described as case friendly. Correct alignment is still important so the case edge does not push against the film.

Will the protector affect fingerprint unlocking?

The MEZON hydrogel protector is listed as fingerprint-sensor compatible. After installation, test fingerprint recognition and, if necessary, re-register your fingerprint for the best result.

What should I look for in a HONOR 400 Pro case?

Prioritise exact model fit, raised edges around the screen and camera area, good side grip and compatibility with wireless charging.
