Galaxy S21 FE Case Magnetic Clear Double-Sided Tempered Glass Cover

Why the Galaxy S21 FE Magnetic Clear Double-Sided Tempered Glass Cover Is Essential for Minimalists and Style-First Commuters

Picture pulling your Galaxy S21 FE out at a café and watching someone at the next table do a double take — because your phone looks completely bare, yet it is sealed inside a 360-degree fortress of glass and aluminum. That is the trick this case pulls off. Sixteen high-strength magnets snap a metal frame around your Galaxy S21 FE (2022, 6.4-inch Dynamic AMOLED display), clamping reinforced tempered glass over both the front and the back, so every millimeter of your phone is covered while every millimeter stays visible.

Built for design lovers who refuse to hide their phone's color, commuters who toss their phone in a bag with keys, office professionals who want clean lines, and anyone tired of yellowing silicone, this is the best Galaxy S21 FE magnetic clear case for showing the phone off without leaving it exposed. Seven frame colors — Black, Blue, Gold, Green, Red, Silver, and Violet — let you accent the phone instead of smothering it. Welcome to the Gorilla Family.

Key Features

• 7 frame colors: Black, Blue, Gold, Green, Red, Silver, and Violet anodized aluminum — pick a match or a contrast for your S21 FE colorway.
• Premium materials: aerospace-grade aluminum alloy frame plus reinforced 9H tempered nano-glass panels front and back.
• Case type: double-sided magnetic snap case — two halves clamp together around the phone with no screws, no adhesive, no bulky clips.
• 16-point magnetic closure: sixteen embedded magnets pull the frame together with a satisfying snap and a seamless, gap-free joint.
• 360-degree coverage: front glass, back glass, and a full metal perimeter — the entire phone is enclosed, including the screen.
• Screen protection: the front tempered glass panel acts as a built-in screen protector with anti-scratch, anti-fingerprint coating.
• Camera protection: the rear chassis is raised 0.3 mm around the lens module so the camera never touches the table.
• Charging compatibility: Qi wireless charging works without removing the case; note this is a magnetic-closure case, not a MagSafe case — the magnets hold the frame shut rather than aligning chargers.
• Signal-safe engineering: antenna-line breaks in the frame keep 5G, Wi-Fi, and Bluetooth at full strength despite the metal construction.
• Precise cutouts: exact openings for the USB-C port, speakers, microphones, and buttons — every cable and accessory connects normally.
• Compatibility: fits the Samsung Galaxy S21 FE (2022, 6.4-inch) ONLY. It does NOT fit the Galaxy S21, Galaxy S21 Plus, Galaxy S21 Ultra, or Galaxy S20 FE.

Materials Explained — What Tempered Glass and Aluminum Actually Feel Like

The front and back panels are 9H tempered nano-glass — the same hardened material as premium screen protectors. It feels exactly like your phone's own screen: cold to the touch, perfectly smooth, and immune to keys and coins. The oleophobic coating means fingerprints wipe off with a shirt sleeve instead of smearing.

The frame is anodized aluminum alloy, the metal used in laptop bodies and bicycle frames. It gives the case its structure and its premium, jewelry-like edge feel — nothing like the soft flex of a TPU bumper. Sixteen magnets are embedded along the rails, so closing the case feels like shutting a well-made watch box.

Altogether the case weighs about 2.1 oz (60 g) and adds roughly 2.5 mm of thickness — remarkably lean for full front-and-back glass coverage, and slim enough to slide into a shirt pocket.

Real-World Use Cases

• The Design Lover: bought the Olive S21 FE for its color and refuses to cover it — the clear glass back keeps the finish on display while the Violet frame adds a custom accent.
• The Commuter: phone rides in a bag with keys, chargers, and a water bottle — front and back glass means no mystery scratches at the end of the week.
• The Office Professional: slim metal edges and a bare-glass look read boardroom-appropriate where chunky rugged cases do not.
• The Wireless-Charging Devotee: drops the phone on a charging pad at the desk and nightstand without ever popping the case off.
• The Gift-Giver: a sleek, under-$50 upgrade that looks far more expensive than it is — seven colors make it easy to match the recipient.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S21 FE with a microfiber cloth on both sides — any dust trapped under glass stays visible, so take an extra minute here.
2. Lay the phone face-down into the front half so the screen sits flush against the front glass panel.
3. Lower the back half over the phone, aligning the camera cutout first.
4. Let the 16 magnets pull the halves together, then press gently around the full perimeter until the seam is even all the way around.
5. Test the buttons, USB-C port, and speakers, then re-register your fingerprint with the front glass in place for the most reliable unlocking.

Troubleshooting and Tips

• Fingerprint sensor missing reads? Delete and re-enroll your fingerprint with the case installed, and enable "Touch sensitivity" in Settings > Display — the optical sensor then reads through the front glass reliably.
• Wireless charging slow to start? Center the phone on the pad — the metal frame narrows the sweet spot slightly. A 15 W pad charges the S21 FE through the case without trouble.
• Seam not closing flush? Open the case and check for grit on the magnet rails; even a grain of sand can hold a corner proud.
• Dust speck trapped under the glass? Pop the halves apart (they separate with a firm thumb push at the corner), wipe with the included-style microfiber motion, and re-close.
• Cleaning the glass and frame? Use a barely damp microfiber cloth — never alcohol wipes, which can degrade the anti-fingerprint coating and dull the anodized finish.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S21 FE (2022, 6.4-inch) only. It does NOT fit the Galaxy S21, Galaxy S21 Plus, Galaxy S21 Ultra, or Galaxy S20 FE — the magnet positions and camera cutout are sized specifically for the FE.

What comes in the box?
The two-piece magnetic case: front frame half with tempered glass panel and back half with clear tempered glass and the aluminum perimeter.

Does it work with wireless charging or MagSafe?
Qi wireless charging works with the case on — no need to remove it. To be clear, the magnets are for the case closure, not MagSafe; Samsung phones do not use MagSafe accessories natively, and this case does not add that system.

What is the drop protection rating?
The aluminum frame and shock-dispersing glass panels are rated for drops of 6 ft / 1.8 m onto hard surfaces. It is a style-and-scratch shield first — if you work on scaffolding, a heavy-duty case is the better tool.

Does the under-display fingerprint sensor still work?
Yes — re-register your fingerprint after installing the case and turn on the increased touch sensitivity setting; reads are then quick and consistent through the front glass.

Are the buttons and ports accessible?
Yes. The frame has precise cutouts for the power and volume keys, USB-C port, speakers, and microphones — cables and headphone adapters connect normally.

Do I need a separate screen protector?
No — the front tempered glass panel is the screen protector. Adding another underneath will prevent the case from closing flush.

Can I attach a lanyard or strap?
No — the sealed glass-and-metal design has no lanyard hole. The trade-off is the seamless look.

Will it yellow or fade over time?
No — tempered glass cannot yellow the way clear TPU does, and the anodized aluminum frame keeps its color. This is the clear case that still looks new in a year.

Is it professional enough for work and meetings?
Very — the bare-glass look with a slim Silver or Black metal edge is about as boardroom-friendly as a phone case gets.

Is this a good gift?
Yes — it photographs beautifully, feels premium out of the box, comes in seven colors, and free 30-day returns cover you if they want a different shade.

Will the magnets affect my phone, cards, or signal?
No — the magnets are positioned along the frame away from the phone's internals, and antenna-line breaks keep 5G, Wi-Fi, and Bluetooth at full strength. Keep magnetic-stripe hotel keys from resting directly on the rails for long periods.

Is it hard to take on and off?
No tools, no prying — the halves separate with a firm push at a corner and snap back together in seconds, which also makes deep cleaning easy.

How much does it weigh?
About 2.1 oz / 60 g, adding roughly 2.5 mm of thickness — slim and pocketable for a case that covers both faces of the phone in glass.

What is the return policy?
Yes — Gorilla Cases offers free 30-day returns on all Galaxy S21 FE cases. If the case doesn't fit your Galaxy S21 FE or you're not satisfied, contact our team within 30 days for a fast replacement or full refund. No restocking fees.

What Gorilla Family Customers Are Saying

★★★★★
Looks like no case at all
I bought the Lavender S21 FE specifically for the color and every case I tried buried it. This one shows the whole back through the glass and the Violet frame matches perfectly. People keep asking if my phone is naked.
— Alyssa G., Portland, OR

★★★★★
Snap-on installation is genius
The magnets pull the halves together so cleanly there is no visible seam. Survived a fall off my desk onto laminate without a mark. Wireless charging on my nightstand pad works fine with the case on.
— Daniel W., Vancouver BC, Canada

★★★★★
End of the scratched-screen era
My phone shares a handbag with keys and a metal water bottle. Three months in and both sides are flawless under the glass. Fingerprint unlock worked normally after I re-registered my thumb.
— Naomi K., Chicago, IL

★★★★★
Classiest case in the office
I work in client services and the chunky cases looked wrong with a suit. The Silver frame on this looks like the phone shipped this way. Slim enough for a shirt pocket, which my old case never was.
— Oliver T., London, UK

★★★★½
Beautiful, with one learning curve
Gorgeous case and the raised lip has already saved my camera once. Only gripe: I had to re-do my fingerprint and bump up touch sensitivity before the sensor behaved, and the glass shows fingerprints by end of day. A quick wipe fixes it — still my favorite case so far.
— Megan R., Austin, TX
