How to set custom dialer as default on Nexus 5? I have a Nexus 5 with root permissions. Google Dialer annoys me. I installed ExDialer &amp; Contacts. How to set this Dialer as my default dialer? 

I will welcome any advice.
This isn't hard.First,you need to disable phone by defaults.go to "manage app",select phone...clear defaults.then go to the menu,remove the phone icon and replace with the exdialer...then i think it should be easy from there on....any where you get a prompt select the exdialer
