Perhaps I'm completely missing this, but I can't trigger the paste text action on Ice Cream Sandwich in any reliable manner. I end up having to type a letter, then double tap around and eventually hope I get the paste option.
Is there a link or tutorial somewhere on how copy / paste / select text is supposed to work?
Select the text you want to copy and then long press on it, you will then see a header towards the top of the phone with different icons for copy, cut and something else. Then go to the field you want to paste it into and long press on it, you will then see the paste option. Hope this helps.
What do you mean "the fields to highlight?" Use the blue markers to select what text you want to copy, then tap the copy button at the top. When you want to paste, long press the text box and paste should appear right above where the cursor is currently position. Just tested it and it works fine on my Prime.
