hello guys am new here and i have this problem with my nexus 4, every time i want to place a phone call after i click on dial it takes 5 to 30 seconds on a black screen with a loading circle on it then it comes the picture of my contact and the call gets place, and it does this regardless if i pick a contact from my contact list or i dial the number its the same, and i have a nexus 4 with all the updates not rooted with nova gui.....any ideas on why is that happening?
