Galaxy S21 Plus Magnetic Tempered Glass Case

Why the Galaxy S21 Plus Magnetic Tempered Glass Case Is Essential for Design Purists and Busy Professionals

You chose the Galaxy S21 Plus partly because it is beautiful — so why entomb it in opaque rubber? This magnetic tempered glass case sandwiches your phone between two panes of high-definition tempered glass inside a magnet-lined aluminum frame: hold the frame near your phone and it snaps itself into place, then a bottom safety lock clicks shut so a hard drop can never pop the case open. The front pane doubles as a built-in screen protector, the back pane shows the phone's true color, and both wireless charging and fingerprint unlock work straight through. Built for design lovers, office professionals, commuters, students, and anyone who wants 360-degree coverage without 360 degrees of bulk, this is the best Galaxy S21 Plus magnetic glass case for full-body protection in plain sight. Welcome to the Gorilla Family.

Key Features

• 7 frame colors: Black, Blue, Green, Pink Purple, Red, Rose Gold, and Silver.
• Premium materials: magnet-embedded aluminum alloy frame with front and back 9H tempered glass panels.
• Case type: double-sided magnetic adsorption case — the frame pulls itself shut around the phone.
• Safety lock upgrade: a mechanical latch at the bottom backs up the magnets, so the case stays sealed even through a hard fall.
• Built-in screen protector: the front tempered glass pane covers the 6.7-inch display — no separate protector needed.
• Crystal-clear back: HD glass shows off your phone's original finish instead of hiding it.
• Screen and camera protection: the aluminum frame edges rise above both glass faces, keeping them off any surface.
• Charging compatibility: Qi wireless charging works through the ultra-thin glass back, and the in-display fingerprint reader works through the front. This is not a MagSafe case — the magnets hold the case together, not accessories.
• Precise cutouts: easy access to all ports, speakers, and buttons.
• Drop protection: frame-first impact design rated for drops up to 6 ft / 1.8 m.
• Compatibility: offered in four sizes — Galaxy S21, S21 FE, S21 Plus, and S21 Ultra. Choose your exact model; each size fits its phone ONLY. It does NOT fit the Galaxy S20 series or S22 series.

Materials Explained — What Tempered Glass and Aluminum Actually Feel Like

Both panels are tempered glass — heat-strengthened like car side windows and glass cooktops — polished to the same slick, cool feel as your phone's own front. The front pane is your screen protector; the rear pane is a display case for the phone's finish. Together they deliver the rare combination of full coverage and full visibility.

The frame is aluminum alloy with magnet points embedded around its full perimeter — the same magnetic-closure idea as premium laptop lids. Bring the halves near the phone and they pull themselves into alignment with a satisfying snap; the bottom safety lock then adds a mechanical guarantee on top of the magnetic one. That two-layer closure is the upgrade that separates this generation from older magnetic cases.

Altogether the case weighs about 1.9 oz (55 g) and adds roughly 2.5 mm of thickness — genuinely slim for something protecting both faces of the phone in glass.

Real-World Use Cases

• The Design Purist: bought the phone in Phantom Violet and intends for people to see Phantom Violet — the clear glass back obliges.
• The Office Professional: the rose gold aluminum frame reads jewelry, not gadget armor, in client meetings.
• The Commuter: phone slides in and out of bags all day; glass on both faces means zero scratch anxiety.
• The Student: built-in screen protector plus case in one purchase — one less thing to buy, install, or replace.
• The Gift-Giver: seven colors and four sizes mean there is an exact match for everyone on the list.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S21 Plus with a microfiber cloth on both faces — glass-on-glass installs reward a dust-free start.
2. Lay the phone onto the rear glass half, aligning the camera cutout.
3. Bring the front frame close and let the magnetic adsorption pull it into place around the edges.
4. Click the bottom safety lock shut and run a finger around the seam to confirm a flush fit.
5. Test the buttons and ports, then re-register your fingerprint through the front glass (enable "Screen protector mode" in Settings).

Troubleshooting and Tips

• Fingerprint unlock hesitating? Re-enroll your prints with the case on and switch on "Screen protector mode" — thirty seconds, permanent fix for most users.
• Halves not aligning? Let the magnets do the work — hover the frame rather than forcing it, and it will self-seat.
• Wireless charging slow? Center the phone on the pad; the glass back is Qi-friendly but alignment still matters on weaker pads.
• Worried about glass-on-glass rattle? The frame suspends both panes with micro-gaskets — if you hear movement, re-click the safety lock fully.
• How should I clean it? Microfiber cloth on the glass, damp cloth on the frame. Avoid alcohol wipes on the colored aluminum — they dull the finish over time.

FAQs

Which phones does this case fit?
It comes in four sizes: Galaxy S21 (6.2-inch), Galaxy S21 FE (6.4-inch), Galaxy S21 Plus (6.7-inch), and Galaxy S21 Ultra (6.8-inch). Choose the variant for your exact model — each size fits its phone ONLY. It does NOT fit the Galaxy S20 series or S22 series.

What comes in the box?
The complete two-piece magnetic case — front frame with tempered glass, rear glass half, and the safety lock built in. No separate screen protector needed.

Does it work with MagSafe or wireless charging?
Qi wireless charging works through the ultra-thin glass back. The magnets are for holding the case together — this is not a MagSafe accessory mount.

Does the fingerprint sensor work through the front glass?
Yes — the in-display reader works through the built-in tempered glass. Re-register your fingerprint after installation for the most reliable unlock.

What is the drop protection rating?
The aluminum frame and dual-pane design are rated for drops up to 6 ft / 1.8 m — and the safety lock keeps the case sealed through the impact.

Can the case really not pop open in a drop?
That is the double-protection upgrade: magnetic adsorption holds the frame, and the mechanical bottom lock backs it up. Even if the phone hits the ground, the halves stay married.

Are all buttons and ports accessible?
Yes — precise cutouts expose the USB-C port, speakers, and microphones, and the frame's button covers stay crisp.

Do I need a screen protector?
No — the front pane is a 9H tempered glass protector. Remove any aftermarket protector before installing.

Will the back glass shatter in a drop?
Tempered glass is designed to absorb and, in a worst-case hit, sacrifice itself — protecting the phone's own back panel. The raised frame keeps both panes off surfaces in normal falls.

Will the clear back yellow over time?
No — glass does not yellow the way clear TPU does. It stays optically clear for the life of the case.

Is it slippery?
Glass is smoother than rubber — the aluminum frame edges provide the grip. If you live dangerously, pair it with a phone strap.

Is it professional enough for work?
It may be the dressiest case we sell — silver and rose gold frames in particular read as premium hardware.

Is this a good gift?
Excellent — seven colors, four sizes, and a wow-factor install. Free 30-day returns cover any size mix-ups.

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

Is it waterproof?
No — it protects against scratches and drops, not submersion. For swimming, choose a dedicated IP68 waterproof case.
