My galaxy s3 has suddenly stopped allowing me to paste texts into any of my apps, except the web browser, or Google chrome. When I long press, it usually gives me the "paste" option. But now it just gives me the "clipboard" option. When I tap on this, nothing happens. I can't get access to the clipboard to see its contents, or empty it, to see if this solves the problem. How do I fix this and get my clipboard functioning as normal again?
