I bought three camera protectors for the iPhone Duo and applied all of them myself. Three completely different approaches: one covers everything, one covers the camera bump, one covers only the lenses. In the video I deliberately avoid a ranking, because the right answer depends on what matters to you. On this page I sort them by purpose instead.
Before you read on: availability in the US
Two of the three protectors I tested are not sold in the US. I bought them in Europe. So that you do not go hunting for them, here is the honest situation:
WSKEN is available and is the one product on this page I tested and can link directly. ROXX and Geemee are not available. For both I link a comparable product that is sold in the US, and I have not tested those alternatives — they are stand-ins, not test results. Every measurement on this page comes from the three units I actually had in my hands.
The thing to know first
The camera lenses on the iPhone Duo are made of A4 glass. In practice only a diamond scratches that, and you probably do not carry one in your pocket. The protectors you stick over them are softer, usually what gets called H glass. So you are protecting hard glass with something softer.
That does not make camera protection pointless. Against impacts and against setting the phone down on hard edges it genuinely helps, and a scratched protector costing a few dollars beats a scratched lens. But it will not outlast the original in scratch resistance.
There is a second issue the video makes obvious: on two of the three, the protector stands proud of the case. Lay the phone down and the protector takes the contact. Only the full-coverage Geemee stays below the edge of the case.

- 【Protect Every Lens. Change Nothing Else.】Designed for iPhone Duo, this camera lens protector gives every lens strong everyday protection without changing the camera experience you bought your iPhone for. Military-grade 9H+ aerospace glass helps defend against scratches, cracks, and everyday impacts, while dual-sided AR coating preserves clear, true-to-life photos day or night. Precision color-matched metal rings blend naturally with the original camera design and stay case-friendly, while advanced 3M Pro adhesive keeps each ring securely in place and leaves no residue when taken off. Built for long-term durability, with reliable protection designed to perform for up to 3 years.
- 【NO.1 Military-Grade 9H+ Protection】Designed for iPhone Duo, TORRAS 4-Layer Impact Defense works with aerospace-grade 9H+ glass to absorb and disperse impact energy layer by layer, delivering up to 12X stronger protection. MIL-STD-810H certified and validated through 14,000 drop tests from heights up to 12 ft, 325 lb of pressure testing, and 25,000 scratch tests, it helps defend each lens against scratches from keys, coins, and sand, accidental drops onto concrete, cracks, and costly lens repairs.(For iPhone Duo camera lens protector)
- 【4-Layer Impact Defense, Engineered Like Armor】Ordinary glass relies on surface hardness alone. TORRAS combines aerospace-grade 9H+ glass with 4-Layer Impact Defense, engineered to absorb and disperse 100% of impact energy across four protective layers before it concentrates on a single point. This armor-like structure helps stop cracks from spreading and delivers 12X greater crack resistance than ordinary protectors—backed by 0 reported lens breakage cases to date, giving your iPhone Duo lens protection built to feel virtually unbreakable.
- 【Clear Photos, Just Like Without a Protector.】Preserve the original image quality of your iPhone Duo with lens-level clarity and true-to-life color. Each individual lens ring uses optical-grade glass with double-sided AR coating and up to 100% light transmittance, keeping photos clear day or night—even with the flash on. No glare, no flare, no haze. Unlike full-camera plate protectors that can limit the light reaching the camera sensor and interfere with LiDAR or depth sensing, the individual-ring design leaves LiDAR and depth sensors completely uncovered, preserving the original camera experience.(For iPhone Duo lens protector)
Best looking, and my pick overall: Torras. 28.98 dollars. The ROXX I tested is the one that disappears completely into the device, and since it is not sold in the US, Torras is the alternative I would reach for here. Same idea: lens-only coverage with colour matching. I did not test this specific model in this video — Torras is a brand I have tested repeatedly in my other iPhone Duo videos, which is why it is the one I am comfortable pointing you to.

The one product here I tested and that you can buy in the US. It covers the camera bump and is sold as titanium blue. The approach sits between the other two: more area than lens-only coverage, but the flash and LiDAR stay clear.
14.99 dollars for one. In the box: a card with a QR code and cleaning supplies — but no wet wipe, and no removal tool either. At this price both are thin.
The main problem is the colour. The iPhone Duo’s night blue reads almost black in dim light and turns into a deep blue in sunlight. The WSKEN pulls noticeably towards purple and does not match. With a case fitted you barely notice it; without one you see it immediately.
The flash is generously cut out, no problems there. On the LiDAR sensor I am genuinely unsure, it sits slightly deeper. If you have experience with that, the comments under the video are open.
✓ Flash generously cut out
✓ Very thin, barely adds any height
✓ With a case on, the colour mismatch barely shows
✓ More coverage than lens-only designs
✓ Tested, and actually available here
✗ Colour pulls purple, does not match the night blue
✗ No wet wipe included
✗ No removal tool
✗ Single piece only
✗ Stands proud of the case
Verdict: Technically fine, with savings made on the accessories and the colour. If you always run a case anyway, you can live with the mismatch.

This is the design I would pick, and it is the one that is not sold here. It covers only the lenses, so the flash and LiDAR stay completely free. 18.90 euros for two in Europe. Full accessories: two cleaning kits, wet wipe, dust sticker, dry cloth, an application template and a removal tool.
The reason to want it is the colour. Applied, you cannot tell anything is on the device. Next to the WSKEN, which pulls purple, the difference is obvious. It also comes in white.
In the US, Torras is the closest equivalent I would point you to, at 28.98 dollars. I have tested Torras repeatedly in my other iPhone Duo videos, though not this specific camera protector.
✓ Colour matching works, visually invisible
✓ Flash and LiDAR stay completely clear
✓ Complete accessories including a removal tool
✓ Two in the pack, cheaper per piece than a single WSKEN
✓ Also available in white
✗ Stands about a millimetre proud of the case
✗ Highest total price of the three
✗ Protects the lenses only, not the bump
✗ The tested unit is not sold in the US
Verdict: If you want camera protection nobody can see, this is the design to look for. The millimetre it stands proud is inherent to lens-only protectors and affects all of them.

The cheapest of the three and the only one covering the entire camera unit — lenses, bump, flash and LiDAR under one continuous clear surface. 6.39 euros for two in Europe.
The big advantage: it is the only one where the case still stands about half a millimetre above it. Lay the phone down and the protector does not touch the surface. With the other two it is the other way round.
The big drawback sits at the flash, which ends up fairly deep under the glass. Night shots are likely to be affected. I did not test that at night, and I say so in the video — it is an expectation, not a measurement. Then there is the look: on a device at this price the continuous plastic face looks out of place.
✓ By far the cheapest of the three
✓ The only one that stays under the case edge
✓ Covers the entire camera unit
✓ Very simple installation, cleaning supplies included
✗ Flash sits deep underneath, night shots likely affected
✗ Covers the LiDAR sensor as well
✗ The most conspicuous option visually
✗ No removal tool included
✗ The tested unit is not sold in the US
Verdict: If maximum coverage is the goal and looks do not matter, this design is hard to beat on price. If you shoot with flash at night, think twice.
Common questions
Does photo quality suffer?
In normal use I notice nothing. A professional will find differences, but anyone shooting professionally is not working on a foldable. The exception is the full-coverage glass, where the flash sits deep underneath.
Do I even need camera protection?
Honest answer: I am not a big fan of it. The lenses are A4 glass and extremely scratch resistant. Against impacts and setting the phone on hard edges a protector still helps, and it is cheaper to replace than a lens.
Does camera protection fit under a case?
Yes, all three still mount with a case on. But only with the full-coverage design does the case still stand above it. With the other two the protector sticks out about a millimetre and takes the contact when you set the phone down.
Is the flash or LiDAR affected?
With the full-coverage design the flash sits deep under the glass and night shots are likely affected. The other two leave both clear or generously cut out.
How do I get a protector off again?
Only the ROXX set includes a tool for it. Keep it. With the others a thin fingernail does the job, and on firmly seated units it gets tedious.
Who is testing here?
I am Sven and I run Case Tester. I buy every product myself, I am not sent anything, and I check on the device rather than on a spec sheet. If something does not work it goes in the test exactly as it happened. And where I am guessing rather than measuring, I say so — as with the flash and the LiDAR sensor here. Where a product I tested is not sold in your country, I say that too, instead of linking something else and letting you assume I tested it.
