【iOS 26.3】不具合バグ修正情報・新機能・変更点・いつ公開・インストール時間・やり方など

iOS 26.3 is basically Apple saying: “Fine, you can leave… but we’ll help you pack properly.” 😏📦📱

The upcoming update is testing:

• A more user‑friendly tool to move from iPhone to Android (and back) so your messages, notes, passwords and more don’t feel trapped.​
• EU‑focused changes for wearables and notifications to line up with the Digital Markets Act.​
• A bunch of behind‑the‑scenes polish, with rollout tipped for late Jan/early Feb 2026.​

It’s less “shiny new toy” and more “your whole ecosystem just got less painful.”
