Overview
- Apple announced on Friday that well over 100,000 App Store titles have been built or updated for iPhone Duo using the iOS 27.1+ SDK, and the company says thousands more optimized apps are added each day.
- The app push has been driven by hands‑on support, with Apple running more than 50 in‑person workshops across 19 cities that drew over 2,000 developers to test and update their apps for the Duo.
- Despite the milestone, many widely used apps remain unoptimized and some Duo updates still show layout bugs or black bars, so the practical app experience varies by title and will keep improving over the coming months.
- Apple has acknowledged a small number of inner‑display cracks along the hinge and is replacing eligible devices, but low early yields and limited spare parts are slowing repairs and making out‑of‑warranty fixes costly.
- Early buyers report hardware tradeoffs that shape daily use — a 5.4‑inch outer screen, 7.6‑inch inner screen, a 4MP under‑display front camera, Touch ID instead of Face ID, and a roughly 254 g weight — and Apple is soliciting user feedback by email surveys as it works on software updates and service solutions.
