How to turn off iOS 26 full-screen screenshot previews

Apple’s iOS 26 introduces an unobtrusive but noticeable change: screenshots now open in a full-screen preview immediately after capture. The new view surfaces editing tools right away, but it also commandeers the whole display instead of shrinking to the familiar thumbnail in the lower-left corner.

What changed in iOS 26

Previously, screenshots appeared as a temporary thumbnail you could ignore. iOS 26 swaps that for a full-screen preview so you can immediately crop, annotate, or interact with the image. For many users this is helpful, but for others it’s intrusive—especially during quick captures or demos.

How to revert to the old thumbnail behavior

• Open Settings on your iPhone.
• Go to General > Screen Capture.
• Toggle off Full-Screen Previews to restore the temporary thumbnail behavior.

Disabling Full-Screen Previews reduces disruption but doesn't remove the editing tools. After you capture a screenshot, the small thumbnail still appears; tapping it opens the same screenshot interface where you can crop, annotate, or act on the image.

What you can still do from the screenshot interface

• Crop or annotate images with Apple’s markup tools.
• Search for similar images using Google integration.
• Use ChatGPT to analyze image contents or Apple Intelligence to summarize text.
• Capture just the visible portion of a webpage or an entire page.

For power users the immediate preview speeds workflows that require quick edits. For others—especially people presenting their screens or using devices for demos—the thumbnail approach is less disruptive. The toggle gives users a simple way to choose which behavior fits their needs.

IT administrators and product teams should take note. Small UX changes in OS updates can affect training materials, accessibility workflows, and scripted demos. Organizations that manage fleets of iPhones may want to update guidance, consider managed configuration options, or inform users about the toggle to avoid confusion.

Developers and designers should also view this as a reminder: OS-level UI shifts can change how users interact with your app’s screenshots and sharing flows. Test flows on the new default and the alternate setting to ensure your app handles both gracefully.

Bottom line: if iOS 26’s full-screen previews get in your way, restore the thumbnail in a few taps via Settings > General > Screen Capture. You’ll keep all of Apple’s screenshot tools, but avoid the immediate takeover of your screen.
