iPhone Duo screen protectors

Yes, the iPhone Duo has two screens that each need their own protector: an inner screen of 7.6 inches, used unfolded, and an outer screen of 5.4 inches, used folded. A protector for one screen does not fit the other because size, shape and the fold differ. The inner screen bends along the hinge, so its protector must be made specifically for that folding display. The outer screen stays flat, which gives you more choice in materials. Check which screen the product description names.

Tempered glass adds a harder layer that helps against scratches and knocks on the outer screen of 5.4 inches. Film is thinner and more flexible but offers less impact resistance. Glass feels close to the original screen surface; film adds very little thickness, which suits a slim case. Do you often carry the folded iPhone Duo in a bag with keys? Choose tempered glass. Do you want the slimmest possible fit? Choose film.

Yes, but only a flexible protector designed explicitly for the folding inner screen of the iPhone Duo. A rigid glass sheet cannot bend with the fold and is not suitable for this screen of 7.6 inches. The inner screen has a small display crease and an anti-reflective coating, so the protector has to be cut and shaped for this exact panel. Check that the description names the iPhone Duo inner screen, and apply it with the device fully unfolded on a flat surface.

A clear protector keeps the sharp image of the inner screen (1878 x 2670 pixels, ~430 ppi) closest to how it looks unprotected, while a matte protector reduces glare and fingerprints but can slightly soften fine detail. Matte also feels less slippery under your fingertips. Do you mainly watch video or edit photos on the unfolded screen? Choose clear. Do you often read or work outdoors or under bright lighting? Choose matte, made for the folding inner screen.

Yes, the iPhone Duo supports a stylus, and you can keep using it with a thin protector suited to touch input. Thick or badly fitted layers can make pen input feel less direct. A smooth clear surface lets the tip glide easily, while a matte surface adds friction that many people prefer for handwriting and sketching. Planning to draw on the unfolded inner screen? Check that the protector is made for the iPhone Duo inner screen and mentions stylus use.
