Galaxy S21 Ultra Magnetic Case with Screen Protector – Gorilla Cases

Why the Galaxy S21 Ultra Magnetic Case with Screen Protector Is Essential for Field Workers and Frequent Travelers

Picture pulling your Galaxy S21 Ultra out of your jacket at airport security, watching it slip, and hearing it hit the tile — face down — with nothing but a click echoing off the floor. You pick it up and the built-in tempered glass took the hit, not your screen. This magnetic case wraps your S21 Ultra (2021, 6.8-inch Dynamic AMOLED display) in an anti-shock aluminum alloy frame, a built-in tempered glass front screen protector, and a crystal-clear back panel, all snapped together by strong magnetic adsorption — no screws, no clips, no fuss. Built for construction professionals, frequent travelers, commuters, photographers who baby that 108 MP camera, and anyone tired of fiddly case installations, this is the best Galaxy S21 Ultra magnetic case with a screen protector built in. Welcome to the Gorilla Family.

Key Features

• 7 color choices: Black, Blue, Gold, Light Purple, Red, Silver, and Violet — each frame is finished in a scratch-resistant matte coat while the back stays fully transparent.
• Premium materials: anti-shock aluminum alloy frame, 9H tempered glass front panel, and a clear scratch-resistant back panel.
• Case type: two-piece double-sided magnetic adsorption case — the front and back halves snap together around your phone in about one second.
• Magnetic locking frame: built-in magnets along the full rail pull the halves into precise alignment and hold them sealed, so the case never pops open in a drop.
• 360-degree full-body protection: dual-layer front-and-back coverage shields the screen, back glass, and camera surround from drops, scratches, and dust.
• Built-in screen protection: the HD tempered glass front sits flush over the 6.8-inch display with full touch sensitivity for typing, gaming, and swiping.
• Camera protection: a raised frame lip keeps the S21 Ultra's large camera module off tables, with an overall drop rating of 6.6 ft (2 m).
• Charging compatibility: Qi wireless charging works through the slim back panel on most chargers. This is a magnetic-frame case, not a MagSafe case — it does not add MagSafe accessory snap-on.
• Precision cutouts: full access to the USB-C port, buttons, microphones, and speakers with zero interference.
• Show-off transparency: the clear back keeps your Phantom Black, Phantom Silver, or any other Samsung finish on display.
• Compatibility: designed for the Samsung Galaxy S21 Ultra (2021, 6.8-inch) ONLY. It does NOT fit the Galaxy S21, S21 Plus, S21 FE, S20 Ultra, S22 Ultra, or Note 20 Ultra.

Materials Explained — What Aluminum Alloy and Tempered Glass Actually Feel Like

The frame is machined from aluminum alloy — the same family of metal used in aircraft seat rails and high-end bike components. It feels cool, rigid, and precise in the hand, with smooth chamfered edges that grip without digging into your palm. Unlike a plastic bumper, aluminum does not flex or creak; it spreads a corner impact along the entire rail instead of letting it concentrate at one point.

The front panel is 9H tempered glass — the same material as your phone's own screen, which is exactly what it feels like. Swipes glide naturally, the coating shrugs off fingerprints, and HD clarity means you forget it is there. The transparent back panel is hard and scratch-resistant, so keys and coins leave your phone's real back glass untouched.

Altogether the case weighs about 2.8 oz (79 g) and adds roughly 2.5 mm of thickness — remarkably trim for a case that brings its own metal frame, screen protector, and clear back in one package.

Real-World Use Cases

• The Construction Professional: drops the phone off a ladder onto subfloor and trusts the aluminum rails and 6.6 ft / 2 m rating to take the hit.
• The Frequent Traveler: wants the whole device sealed — front, back, and edges — before it disappears into seat-back pockets and security bins.
• The Commuting Professional: installs and removes the case in seconds when switching between a car mount and a pocket carry.
• The Mobile Photographer: keeps the S21 Ultra's 108 MP camera module raised off every surface it gets set down on.
• The Gift-Giver: picks Violet or Gold for an S21 Ultra fan because the magnetic install takes one second and needs zero tech skills.

Feature-to-Benefit Mapping

Step-by-Step Installation Guide

1. Clean your Galaxy S21 Ultra with a microfiber cloth, paying extra attention to the screen and camera ring so no dust gets sealed inside.
2. Lay the phone into the back half of the case, aligning the camera cutout first.
3. Lower the front frame over the screen and let the magnets pull the two halves together — you will hear a soft click as they seat.
4. Run a fingertip around the frame to confirm the seam is flush on all four sides with no gaps.
5. Test the buttons, USB-C port, and speakers, then re-register your in-display fingerprint with "Screen protector mode" enabled in Settings, since the case includes a built-in glass front.

Troubleshooting and Tips

• Fingerprint unlock suddenly less reliable? Delete your stored prints and re-enroll them through the tempered glass, then switch on Samsung's "Screen protector mode" under Display settings.
• Wireless charger not connecting? Center the phone on the pad — dual-layer magnetic cases charge fine but are less forgiving of off-center placement than bare phones.
• Halves feel stiff to separate? Twist gently from a corner rather than pulling straight apart — the magnets release progressively and loosen up after the first week.
• Dust speck trapped under the front glass? Separate the halves, wipe both surfaces with the microfiber cloth, and re-seat — the magnetic design makes re-installation a ten-second job.
• Smudges on the glass? Wipe with a barely damp microfiber cloth only — avoid alcohol wipes, which can degrade the oleophobic coating and the frame's matte finish over time.

FAQs

Which phones does this case fit?
It fits the Samsung Galaxy S21 Ultra (2021, 6.8-inch) only. It does NOT fit the Galaxy S21, S21 Plus, S21 FE, S20 Ultra, S22 Ultra, or Note 20 Ultra — those models have different dimensions and camera layouts.

What comes in the box?
The magnetic front frame with integrated tempered glass and the back frame with clear panel. No tools are required — the magnets do the work.

Does wireless charging work through the case?
Yes — Qi wireless charging works on most pads without removing the case. Note that this is a magnetic-adsorption case, not a MagSafe case, so it does not add snap-on MagSafe accessory support.

What is the drop protection rating?
The aluminum frame and dual-layer design are rated for drops of 6.6 ft (2 m) onto hard surfaces.

Will the in-display fingerprint sensor still work?
Yes. The S21 Ultra's ultrasonic sensor reads through the tempered glass — just re-register your fingerprints after installing and enable "Screen protector mode" for best accuracy.

Does it include a screen protector?
Yes — a 9H HD tempered glass protector is built into the front frame, so you do not need to buy or apply a separate one.

Are the buttons and ports accessible?
Yes — precision cutouts leave the USB-C port, speakers, and microphones fully open, and the frame's button covers stay clicky.

Is the touchscreen still responsive under the glass?
Yes — the tempered glass front is engineered for full touch sensitivity, so typing, gaming, and swiping feel exactly like the bare screen.

Will the metal frame block my signal?
No — the frame uses engineered antenna gaps so 5G, Wi-Fi, NFC, and Samsung Pay signals pass through undisturbed.

Can I attach a lanyard or strap?
No, this model does not include a lanyard hole. If you need a strap or clip, browse our holster-style S21 Ultra cases instead.

Will the case yellow or fade over time?
No. Tempered glass and the coated aluminum frame do not yellow the way clear TPU does, and the color finishes resist fading and peeling.

Is it professional enough for work and meetings?
Absolutely — the slim metal frame and clear back read as premium, especially in Black or Silver, and it slips easily into a suit pocket.

Is this a good gift?
Yes — seven color options, one-second magnetic installation, and free 30-day returns make it an easy, low-risk gift for any S21 Ultra owner.

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

Can I remove the case quickly for cleaning or a mount swap?
Yes — twist from a corner and the magnetic halves separate in seconds, then snap back together just as fast. No screws or tools at any point.
