So you saved something that you typed on your iPhone. You may have used the new gesture in iOS 13. You may have deliberately or accidentally shaken your iPhone to trigger the traditional undo method. Either way, if you want your text back or repeat editing, you're not sure how to do it. Fortunately, this is as easy as wiping.
If your iPhone has been upgraded to iOS 13, you can now use the new repeat gesture. All you have to do is swipe right across your display with three fingers. That's it. Once you have done this, "Restore" will be displayed at the top of the screen. However, if there is nothing to repeat, iOS says exactly that at this point.
You will find out that this New redo gesture on your iPhone works. That is, it works in popular iOS apps such as Mail, News, Notes, and Safari, but also on Facebook, Twitter, and other third-party apps you use. As you upgrade to iOS 13, you'll need to learn more gestures and try new features.
