One of the many unpublicized changes introduced with the iOS 26 update released earlier this week is that screenshots now automatically open into a full-screen preview. The new approach provides immediate access to a handful of useful tools for editing a screenshot, but they now dominate your iPhone's screen when captured, instead of shrinking into an unobtrusive thumbnail. Thankfully, reverting to the old way iOS handled screenshots is easy, as spotted by 9To5Mac.
"Screenshots are the most universal method of capturing digital information... It's this portable data format... there's nothing else that's quite so portable that you can move between any piece of software."
