Hackers Keyboard has that via ctrl+z, but only in horizontal mode. For this only i had my Galaxy S3 in horizontal per default. But can’t do that with modern phones’ aspect ratio and i’m missing undo since then.

Edit: i’ll go with Heliboard for now.

    Undo is a function of the Android API, not the keyboard. All phones can do it. It is usually the app’s responsibility to implement its button because the feature extends beyond the realm of text input.

      Some keyboards suggested here can do it tho, since most apps with text input don’t implement undo.
