iOS 27: Paste sometimes duplicates text, then keyboard stops working

Sorry for the late reply.

I’d like to clarify the issue. It only happened occasionally. After I pasted an image, I sometimes could not type with the keyboard. This only happened when I pasted the image using the Paste button on the keyboard. Pasting from the menu did not cause this problem.

I haven’t tried this in other apps, so it may have been limited to one app.

I’m now on iOS 27.2, and this issue appears to be fixed.

If, on your iPhone 13 Pro, the text you copy and paste is sometimes appearing twice or getting duplicated, one possibility is that the Paste command may inadvertently be getting triggered twice. This can happen if the paste action is tapped more than once, if there is a slight delay in the app responding and the action is repeated, or occasionally because of the way a particular app handles the paste operation.

However, it is difficult to analyse the issue accurately without knowing which app you are experiencing it in. You have not mentioned the name of the app where the duplicated text appears.

This is important because copy-and-paste behaviour is handled partly by the iOS text system and partly by the individual app. If the problem occurs only in one particular app, it could be related to that app's text field, editing implementation, or compatibility with your current iOS version. If it happens across several different apps, then we should investigate the iPhone/iOS copy-and-paste behaviour more generally.

Please mention:

• The app in which the duplication occurs.
• Your iOS version.
• Whether the duplication happens every time or only occasionally.
• Whether the text is duplicated when using Paste from the context menu, three-finger paste, or another method.

With these details, it will be much easier to determine whether you are inadvertently pasting twice or whether there is an actual copy-and-paste issue with iOS or the particular app.

If the Paste function duplicates the copied text, we need a little more information to identify the cause.

1. Where are you copying the text from, and where are you pasting it? For example, are you copying from Notes, Safari, or another app and pasting into a text field, an email, or a website?
2. What happens when you use Undo (Shake to undo)? Does it remove both copies of the duplicated text, or does it remove only one and leave the other intact?

Also, does the duplication occur immediately after pasting, or does it happen only in a particular app or website? 

These details will help narrow down whether the problem is related to the source app, the destination app, or the way the destination handles pasted text.
