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.

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