Does it work on the big screen?
The independent tracker for iPhone Duo. Which apps fill the 7.6-inch inner display, which screen protectors actually fit, and what reviewers agree on — checked by hand, updated every day.
Compiled with the iOS 27.1 SDK. Resizes to fill the inner display and supports Split View and the half-folded pose.
3 apps Partial iOS 27, not yet 27.1Uses most of the inner display but leaves blank space at the edges. Works, looks slightly off.
0 apps Letterboxed Not updated for iOS 27Runs in a phone-sized safe area with black borders. Fine on the outer screen, wasted space inside.

Every status is a hand check on a Duo, dated in the Checked column. How we check →
Screen protection, in short
Full guide →The folding panel ships with its own nano-texture cover layer. Tempered glass can't bend. Only flexible films made for the Duo, and the factory layer never comes off.
Apple replaces the cover layer for $19.99 with AppleCare+.
Outer · 5.4″ cover Glass is fine, fit is the catchStandard tempered glass works on the cover screen. The problem is two-piece cases whose front frame overlaps the glass edge. We test each pairing.
Cases Two shells, one hingeApple's own Case and Folio with Kickstand, plus third-party shells. Hinge clearance, Pencil access and protector overlap, in one table.
