Samsung Galaxy S9 Plus Case Slim Aluminum Blue

Why the Samsung Galaxy S9 Plus Slim Aluminum Case in Blue Is Essential for Adventurers and Standout Professionals

Most metal cases come in one mood: black. This one has a personality. The Samsung Galaxy S9 Plus Slim Aluminum Case in Blue locks a four-piece aluminum frame around your 6.2-inch Galaxy S9 Plus (2018) with the included screwdriver, building a Gundam-style metal exoskeleton in a glossy blue that catches light like a sport bike's tank. Beneath the looks: a smooth treated rubber lining that absorbs shock and resists dirt, a shatterproof anti-scratch build, and an open screen face that pairs perfectly with our S9 Plus tempered glass protectors. Built for adventurers, cyclists, standout professionals, design-minded gearheads, and anyone who wants armor with attitude, this is the best blue aluminum Galaxy S9 Plus case on the market. Welcome to the Gorilla Family.

Key Features

• Vivid blue finish: glossy metallic blue over machined aluminum — strong, trendy, and unmistakably yours.
• Premium materials: high-quality aluminum metal frame and back with a smooth treated rubber inner lining.
• Case type: four-piece screw-together metal bumper and back cover that locks around the phone like a chassis.
• Gundam-style design: angular, mechanical lines that make the case a statement piece, not just protection.
• Shock and dirt protection: shock-absorbent, shatterproof, anti-scratch construction that resists dirt and stains.
• Screen protection: a raised metal lip surrounds the display, and the open face works great with our Galaxy S9 Plus tempered glass screen protectors.
• Camera protection: a recessed opening keeps the dual cameras and fingerprint sensor below the metal surface.
• Heavy-duty drop rating: the screw-locked aluminum-over-rubber build is rated for 10 ft / 3 m drops onto hard surfaces.
• Charging compatibility: charges by USB-C cable through the port cutout; the aluminum body blocks Qi wireless charging, and this is not a MagSafe case.
• Tool included: a screwdriver ships in the box — first assembly takes about five minutes.
• Compatibility: fits the 6.2-inch Samsung Galaxy S9 Plus (2018) ONLY. It does NOT fit the smaller Galaxy S9, the S8, S8 Plus, Note 9, or any S10 or newer model.

Materials Explained — What Aluminum and Treated Rubber Actually Feel Like

Aluminum is the same alloy family found in aircraft skins and race-bike frames: stiff, light, corrosion-proof, and cool against the palm. Four machined pieces screw together into a continuous frame, so a drop's energy travels around the whole structure instead of crushing into a single corner. The blue is a bonded metallic finish — deeper and more durable than painted plastic ever manages.

Inside, a layer of smooth treated rubber does the quiet work: damping impact like an engine mount, gripping the phone so it never shifts, and keeping dirt and stains away from the S9 Plus's glass back.

The complete case weighs about 2.8 oz (80 g) and adds roughly 3 mm of thickness — remarkably slim for bolt-together metal, and the reason it still drops into a jeans pocket without a fight.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S9 Plus with a microfiber cloth — install your tempered glass screen protector first if you use one.
2. Loosen the frame screws with the included screwdriver and separate the four sections.
3. Rest the phone in the rubber-lined back section, aligning the camera and fingerprint openings.
4. Fit the blue frame pieces around the edges and tighten the screws in an alternating pattern until snug.
5. Test the buttons, USB-C port, headphone jack, speaker, and fingerprint sensor, and confirm the frame sits flush on every side.

Troubleshooting and Tips

• Screws backing out over time? A quarter-turn with the included driver every couple of months keeps everything tight.
• Qi pad not charging the phone? Metal blocks wireless charging — charge by USB-C cable; it is physics, not a fault.
• Signal concerns? The segmented bumper is built around the antenna lines, and most users measure no real-world difference.
• Frame feels tight on first assembly? Correct — precise tolerances are what keep it silent and rattle-free for years.
• Cleaning the blue finish? A slightly damp cloth keeps the gloss — avoid alcohol wipes, which can dull metallic coatings over time.

FAQs

Which phones does this case fit?
It fits the 6.2-inch Samsung Galaxy S9 Plus (2018) only. It does NOT fit the smaller Galaxy S9, the S8 or S8 Plus, the Note 9, or any S10 or newer Samsung model.

What comes in the box?
One genuine aluminum shockproof case in blue (four sections) and the assembly screwdriver.

Does it work with MagSafe or wireless charging?
No — aluminum blocks Qi wireless charging, and this is not a MagSafe case. Charge by cable through the USB-C cutout.

What is the drop protection rating?
The screw-locked aluminum frame with rubber lining is rated for 10 ft / 3 m drops onto hard surfaces.

Does the fingerprint sensor still work?
Yes — the rear opening leaves the sensor fully exposed, with a metal rim that guides your finger to it by feel.

Are buttons and ports accessible?
Yes — machined cutouts cover USB-C, the headphone jack, and the speaker, while the frame keeps power and volume keys crisply clickable.

Can I use a screen protector with it?
Yes — the open screen face is made to pair with our Galaxy S9 Plus tempered glass protectors for complete coverage.

Is there a lanyard attachment?
No dedicated lanyard hole — browse our phone rings and straps if you want a tether option.

Will the blue fade or chip?
The metallic finish is bonded to aluminum and dramatically outlasts painted plastic; well-earned edge wear after years of abuse is the worst you should expect.

Does the metal affect reception?
The four-piece bumper layout respects the S9 Plus antenna bands — in normal coverage, users report no noticeable change.

How heavy is it?
About 2.8 oz (80 g) — solid enough to feel serious, light enough to forget by lunchtime.

Is it professional enough for client work?
Yes — deep blue machined metal reads as a design choice, more premium accessory than rugged gadget.

Is this a good gift?
One of our favorites for the hard-to-shop-for — distinctive, genuinely protective, and covered by free 30-day returns.

Do I need tools?
Only the screwdriver in the box — assembly is a five-minute job the first time and faster after that.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S9 Plus cases. If the case doesn't fit your Galaxy S9 Plus or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.
