Phone agenda closing automatically

I own a Mx4 for a bout a year and today everytime i am trying to make a phone call and press on the call icon it opens my last calls and automatically clossess it making it impossible to call anyone, i believe somehow it is crashing the agenda app.


Clear cache of the caller app, and please state your firmware
