You installed iOS 26 and noticed the new glossy look — then moved on. That’s where most people lose value: Apple tucked many useful controls and small quality-of-life changes behind long-presses, menus, and hardware gates. The result is wasted time, odd UX surprises, and missed privacy controls. This post surfaces 21 hidden iOS 26 Features that actually save time or protect your data, explains why they matter now, and gives short how-tos so you can use them immediately — not just admire Liquid Glass.
Apple has also confirmed the complete list of supported iPhones, so you know right away whether your device makes the cut.
(Statements about Liquid Glass, Live Translation, Preview, and Messages features are documented by Apple and public coverage.)

What it does: A best-practice mode that signals legitimate automated calls so they survive call screening.
Why it matters: Contact centers and appointment systems can avoid being blocked.
How to use: Work with carrier/Apple verified-caller programs and implement recommended SIP headers.
21. Preview API hooks and PDF interoperability
What it does: New OS hooks let third-party apps offer deep send/export integrations with Preview.
Why it matters: If your app relies on PDF workflows, you can call into system Preview features to keep users in one place.
How to use: Check iOS 26 SDK release notes and adopt the Preview interoperability API.
Key Takeaways
Small UI shifts unlock real productivity: many Liquid Glass behaviors (tab shrink, anchored alerts) save micro-seconds that add up.
Privacy controls matter more than ever: on-device transcription, Live Translation retention, and wired accessory permissions are worth reviewing.
Message features reduce app-switching: polls and conversation summaries make iMessage a light collaboration layer.
Developers and small businesses must test call flows and icons to avoid usability regressions.
Preview’s arrival on iPhone changes PDF workflows — use system interoperability instead of re-inventing the wheel.
