Is Instagram optimized for the iPhone Duo?
Testing at launch — this page goes live with real results
We test Instagram on real iPhone Duo hardware at launch (October 23, 2026) and publish the verdict here: full-screen layout, split-screen behavior, and fold handling.
What we test
| Inner display layout | Does the app use the full ~7:10 screen, or letterbox a phone layout? |
|---|---|
| Split-screen | Does it behave in iPad-style side-by-side multitasking? |
| Fold continuity | Does the session transfer smoothly between cover and inner screens? |
| Crease awareness | Does critical UI land on the fold? |
