Our Top S20 Plus Screen Protector Picks

More Details on Our Top Picks

1. Whitestone Dome Glass 2-Pack

Whitestone's Dome Glass uses liquid optically clear adhesive and a UV curing light, which is the only way to get a tempered-glass protector to truly follow the S20 Plus's slightly curved display edge to edge. You drip the liquid adhesive onto the phone, lay the glass down, and cure it – the result is a protector with no halo effect and no touch dead zones.

The reason this method matters on the S20 Plus is the ultrasonic fingerprint sensor. Air gaps between glass and display are what defeat ultrasonic readers, and the liquid adhesive eliminates the gap entirely, so you can register your fingerprints after installation and unlock reliably. It also self-levels over small existing scratches in the display.

At around $70 for two protectors it costs more than every other pick here combined, and the installation is a genuine 10-15 minute project the first time you do it. But if you want the feel of real glass with full curved coverage and a fingerprint reader that keeps working, nothing else on this list does it as well.

• Hardness: 9H
• Installation: UV liquid LOCA + UV curing light + installation tray
• Pack Size: 2-Pack
• Finish: Clear (glossy)
• Price Tier: Premium

2. amFilm Ultra Glass 2-Pack

amFilm's Ultra Glass borrows the Whitestone playbook: liquid adhesive plus a UV lamp, which bonds the tempered glass directly to the display with no air gap. On the S20 Plus that gap-free bond is what keeps the ultrasonic fingerprint sensor reading through glass that would otherwise defeat it.

The kit is genuinely complete – two glass protectors, liquid adhesive tubes, a UV curing light, cleaning wipes, dust stickers, a microfiber cloth, and an installation manual. Everything arrives in one box, and the two-pack gives you a spare if the first install goes sideways.

The trade-off is that you are signing up for a wet, careful installation: dripping adhesive, aligning glass on a curved screen, and curing under UV while the phone sits level. Take your time with the included frame and the results rival protectors costing twice as much.

• Hardness: 9H
• Installation: UV liquid LOCA + UV curing light + installation tray
• Pack Size: 2-Pack
• Finish: Clear (glossy)
• Price Tier: Mid

3. Spigen NeoFlex 2-Pack

Spigen's NeoFlex is a wet-install TPU film rather than glass, and on a curved phone like the S20 Plus that flexibility is the whole point. The film stretches to follow the display's curved edges for genuine edge-to-edge coverage without the lifting and halo effect that stiff glass can suffer at the curves.

Because it is a thin film, the ultrasonic fingerprint sensor reads through it with no issues – there is nothing to re-register and no sensitivity penalty. The self-healing coating also means the light scuffs that films inevitably collect fade away on their own within a day or two.

Installation uses a spray solution and squeegee, which feels unusual the first time but forgives small mistakes – you can reposition the film while it is wet. Spigen also certifies it as compatible with every Spigen case, so pairing it with a Spigen cover is seamless.

• Hardness: N/A (TPU film)
• Installation: Wet application (spray solution, squeegee)
• Pack Size: 2-Pack
• Finish: Clear (glossy)
• Price Tier: Budget

4. magglass Clear Glass 1-Pack

magglass takes the simple route: a single sheet of 9H tempered glass with an alignment applicator in the box, no liquids and no UV lamps. It is an Encased-brand product with a lifetime warranty behind it, and the dry installation takes about two minutes once the screen is clean.

The glass is cut to the S20 Plus's 6.7-inch display with a case-friendly margin, and it is explicitly engineered for the in-screen ultrasonic fingerprint sensor. Re-register your fingerprints after installation for the most reliable unlocks – that is standard advice for any glass on an ultrasonic phone.

Being honest about the physics: this is a flat-ish glass on a slightly curved display, so it covers the usable flat area rather than wrapping the curve like a film. If you want the glass feel without the UV hassle, this is the straightforward choice – but there is only one protector in the box, so measure twice and apply once.

• Hardness: 9H
• Installation: Dry install with alignment applicator
• Pack Size: 1-Pack
• Finish: Clear (glossy)
• Price Tier: Mid

5. ArmorSuit MilitaryShield 2-Pack

ArmorSuit's MilitaryShield is made from the same TPU film family used to protect military aircraft surfaces, and it brings that pedigree to the S20 Plus with a laser-cut fit for the 6.7-inch display. The film is thin enough that the ultrasonic fingerprint sensor reads through it cleanly.

The standout is ArmorSuit's lifetime replacement warranty: if the protector ever wears out or gets damaged, they replace it. Combined with the film's self-healing properties – small scratches disappear on their own – one purchase can realistically last the remaining life of this 2020 phone.

Installation is the classic wet method with the included spray and squeegee, which takes a few minutes and some patience. The film feels like film, not glass, under your fingertip – but for scratch and scuff protection with case-friendly edges, it is one of the most proven options on this list.

• Hardness: N/A (TPU film)
• Installation: Wet application (spray solution, squeegee)
• Pack Size: 2-Pack
• Finish: Clear (glossy)
• Price Tier: Budget

6. LK TPU Film Kit 2+2

LK's kit gives you two flexible TPU screen films plus two camera lens protectors for the S20 Plus's rectangular camera module – front and back protection in a single purchase. The included positioning tool takes the guesswork out of dry alignment, which is the usual pain point with films.

The films are ultra-thin and self-healing, so minor bubbles and scratches fade within about 24 hours after installation. They are also tuned for the ultrasonic fingerprint sensor, and the case-friendly cut leaves room for most cases.

This is a film kit, so do not expect glass-level drop protection – its job is scratch and scuff defense plus keeping the camera lenses pristine. For the price, bundling lens protection with the screen films makes it one of the most complete packages here.

• Hardness: N/A (TPU film)
• Installation: Dry install with positioning tool
• Pack Size: 2+2 (2 screen + 2 camera lens)
• Finish: Clear (glossy)
• Price Tier: Budget

7. IQShield Clear 3-Pack

IQShield's approach is simple: give you three crystal-clear TPU films so a botched first attempt costs you nothing. The wet installation lets you slide the film into perfect position before squeegeeing out the solution, which makes it one of the most beginner-friendly options for a curved phone.

The film is thin, case-friendly, and fully compatible with the S20 Plus's ultrasonic fingerprint sensor – no re-registration drama, no sensitivity loss. It also resists yellowing, which matters on a phone you may keep for years.

Three packs are the real story here: even if you install one today and the phone lives in your pocket for two more years, you have spares when the first film eventually picks up enough micro-scratches to bother you. For a 2020 phone, that long-tail value is genuinely useful.

• Hardness: N/A (TPU film)
• Installation: Wet application (spray solution, squeegee)
• Pack Size: 3-Pack
• Finish: Clear (glossy)
• Price Tier: Budget

8. JETech Clear 2-Pack

JETech's S20 Plus protector is a simple dry-install TPU film – clean the screen, align, and lay it down. No spray bottles, no UV lamps, no curing time. It is the fastest route from box to protected phone on this list.

The film is HD-clear and thin enough that the ultrasonic fingerprint sensor and the display's touch sensitivity work as normal. It is cut case-friendly, so it sits inside the margins of most cases without peeling at the edges.

Dry films punish crooked placement more than wet ones, so use the dust stickers and take your time with alignment. At this price for two films, it is an easy, low-commitment pick for a phone of this age.

• Hardness: N/A (TPU film)
• Installation: Dry install
• Pack Size: 2-Pack
• Finish: Clear (glossy)
• Price Tier: Budget

9. Geviaho Privacy 2-Pack

Geviaho's privacy protector is proper tempered glass with a two-way privacy filter baked in – look at the S20 Plus straight on and the display is clear; view it from the side and the screen goes dark. It is the only pick on this list that addresses privacy at all, which earns it a slot on its own.

The 3D curved edges give fuller coverage than flat-cut glass, and the 9H rating keeps the usual scratch and scuff protection. Be aware of the honest trade-off with any privacy glass on this phone: the filter layer can interfere with the ultrasonic fingerprint reader, so keep face unlock or a PIN set up as a fallback.

Privacy glass also dims the display slightly even when viewed head-on, so you may run brightness a notch higher than usual. If you read messages on crowded trains or work in open offices, that is a fair price for the privacy.

• Hardness: 9H
• Installation: Dry install
• Pack Size: 2-Pack
• Finish: Privacy (2-way, darkened)
• Price Tier: Budget

10. Ibywind Clear Kit 2-Pack

Ibywind's set is the most complete kit on this list: two flexible TPU screen films, a camera lens protector, and a back film, plus an installation frame and the usual cleaning accessories. If you like your phones fully wrapped, this is the one-box answer.

The included installation frame is genuinely useful on a curved phone – it holds the film in alignment while you lay it down, which cuts the usual film-installation anxiety in half. The films are self-healing and thin enough for the ultrasonic fingerprint sensor.

Realistically, the back film is a bonus most people will skip, but the screen films plus the lens protector cover the parts that actually get damaged. It is film-level protection throughout, so pair it with a case if drops are your main worry.

• Hardness: N/A (TPU film)
• Installation: Dry install with installation frame
• Pack Size: 2-Pack screen + 1 lens + 1 back film
• Finish: Clear (glossy)
• Price Tier: Budget

Factors to Consider When Buying

The Curved Display and the Ultrasonic Sensor: Why the S20 Plus Is Picky

The S20 Plus has a 6.7-inch display with slightly curved 2.5D edges and a Qualcomm 2nd-gen ultrasonic in-display fingerprint sensor. Ultrasonic readers send sound waves through the display — and air gaps between a stiff glass protector and the screen are what defeat them. That is why UV-cured glass (Whitestone, amFilm) works so well here: the liquid adhesive fills the gap completely. If you want glass, pick one of the UV options or be prepared to re-register your fingerprints after install.

UV-Cured Glass vs Dry Glass vs Film

Three installation philosophies appear in this roundup. UV-cured glass (Whitestone Dome Glass, amFilm Ultra Glass) bonds liquid adhesive to the display and cures it with a UV lamp — the best edge-to-edge fit, but a 10-15 minute install. Dry-install glass (magglass, Geviaho) is a two-minute peel-and-stick that covers the usable flat area rather than wrapping the curves. TPU film (Spigen NeoFlex, ArmorSuit, LK, IQShield, JETech, Ibywind) flexes around the curves, installs wet or dry, and never fights the fingerprint sensor — but offers less impact protection than glass. First-timers and case users do well with film; drop-worriers should go glass.

The Ultrasonic Fingerprint Sensor: Re-Register After Installing Glass

The S20 Plus’s ultrasonic sensor is genuinely sensitive to air gaps. After installing any tempered glass protector, delete and re-register your fingerprints — this is the standard fix for slow or failed unlocks. UV-cured glass needs it least (the liquid bond eliminates the gap); dry glass needs it most. Thin films read through with no re-registration drama. If unlock still feels slow after re-registering, try pressing a fraction longer and adding the same finger twice.

Remove Samsung’s Pre-Installed Film Before UV Glass

Samsung shipped the S20 Plus with a pre-installed plastic film on the display. You must peel it off before applying Whitestone or amFilm UV glass — the liquid adhesive needs direct contact with the display, and layering UV glass over the old film traps air and defeats the whole point of the liquid bond. Peel the factory film, clean the screen thoroughly, and then start the UV kit.

Privacy on the S20 Plus

The Geviaho Privacy 2-Pack is the only privacy pick — a 2-way tempered glass that blacks out side viewing angles. It works head-on and keeps shoulder-surfers out on trains and in offices. Be aware of two honest trade-offs: the filter layer can interfere with the ultrasonic fingerprint reader, so keep face unlock or a PIN set up as a fallback, and privacy glass dims the display slightly even head-on, so expect to run brightness a notch higher.

Camera Lens and Full-Body Protection

The S20 Plus’s rectangular camera module sits proud of the back panel — vulnerable to scratches on flat surfaces. LK’s TPU Film Kit 2+2 includes two camera lens protectors alongside two screen films, and the Ibywind Clear Kit goes further with lens and back films plus an installation frame. Lens protectors don’t affect photo quality when installed cleanly. On a phone this age, the bundle is cheap insurance for the cameras.

Compatibility: S20+ 4G and 5G Yes — S20, S20 Ultra, S20 FE No

The Galaxy S20+ 4G (SM-G985) and S20+ 5G (SM-G986) have identical dimensions — every protector here fits both. What does not fit: the Galaxy S20 (6.2 inches), the S20 Ultra (6.9 inches), the S20 FE (6.5 inches), and the Note 20 series. Double-check your model before buying — several of these brands sell look-alike listings for each S20 variant, and a protector cut for the wrong size will not align.
