which application you two talking about?
whatsup? whatsapp?

Best is to uninstall every whats** application. Mitakuuluu too. Then restart device and start from scratch. whatsup, if you don't want to uninstall untick the option start whatsup autmaticall on startup. One message looks like an operater problem. But anyway try to do a clean install. Then we'll see.
