iPhone Duo Screen Protectors
iPhone Duo owners have one job to get right: buy a protector cut for this exact model, not for the family. The cutouts, the sensor housing and the curve of the glass all change between siblings in the same range, and a protector that is 2mm out will lift at a corner within a fortnight.

Check which screen you are buying for
Two displays, two different answers. The 5.4in outer cover screen is ordinary Ceramic Shield 2 and takes a normal tempered-glass protector. The 7.6in inner panel folds and is finished with a nano-texture etch, so it takes neither glass nor a glossy film — covering it replaces the anti-glare finish you paid for.
Protecting more than the screen?
See iPhone Duo cases — a case absorbs the drop before it reaches the glass.

For the iPhone Duo the sensible shortlist is tempered glass and tpu / hydrogel film. Below are the options currently sold into the UK, grouped so you can see the difference between a £6 three-pack and a £30 single protector before you commit.
What to check before you buy for the iPhone Duo
Model note
Two displays, two different answers. The 5.4in outer cover screen is ordinary Ceramic Shield 2 and takes a normal tempered-glass protector. The 7.6in inner panel folds and is finished with a nano-texture etch, so it takes neither glass nor a glossy film — covering it replaces the anti-glare finish you paid for.
Folding display
Never fit tempered glass to the inner folding panel. It will crack along the crease. Only the manufacturer's own film or a purpose-made hydrogel belongs there. The outer cover screen takes normal glass.
Nano-texture display
The anti-glare effect is etched into the glass itself, so covering it with a protector replaces the finish rather than protecting it. A glossy protector cancels it outright; a matte one substitutes a coating for the etch. If you bought the phone for that screen, leave it bare and clean it with the cloth Apple supplies.
Face ID / front sensor array
The cutout must clear the sensor housing. A protector that overlaps it can slow or break face unlock, so avoid trimmed-down universal sheets.
Dynamic Island
Look for a protector with a clean, correctly-sized cutout. Cheap ones leave a visible adhesive ring around the island that catches the light.
iPhone Duo screen protectors — your questions
What size is the iPhone Duo screen?
We do not publish an unverified figure for the iPhone Duo display. Check the manufacturer's spec sheet, and in any case buy a protector listed for the iPhone Duo by name rather than by measurement — diagonal size alone doesn't guarantee a fit.
Which type of screen protector is best for the iPhone Duo?
Tempered glass is the default choice for the iPhone Duo. The default choice. Rigid, glass-clear, absorbs impact by sacrificing itself.
Worth knowing before you buy: can shatter on a hard corner drop; adds noticeable thickness on curved screens.
Can I put tempered glass on the iPhone Duo inner screen?
No. The inner panel is a flexible laminate that bends every time you close the phone, and rigid tempered glass cannot follow it. Fitted there it cracks along the crease, usually within days, and can lift the layer underneath as it goes.
The inner screen already ships with a factory-applied film, leave it there, and have it replaced by the manufacturer when it wears. The outer cover screen is ordinary glass and takes a normal tempered-glass protector without issue.
How much should I spend on a iPhone Duo screen protector?
Somewhere between £8 and £25 covers almost everyone. Under about £8 you're usually buying glass with no oleophobic coating, which looks fine for a week and then smears permanently.
Above £25 you're paying for a warranty, a better applicator, or a speciality finish like privacy or paper-feel. Those are real benefits, but they're refinements. The jump in protection from nothing to a £10 protector is far larger than the jump from £10 to £30.
Will a screen protector fit the iPhone Duo with a case on?
Usually, if you buy one described as case-friendly. Those stop fractionally short of the screen edge so a case lip can sit over the top without catching and peeling it.
Full-coverage and edge-to-edge designs look better but can foul thicker cases. If you already own the case, fit the protector first, then check the case clips down flush before you commit to a second one.
