ashot0539 ,
Look
You have APK file dialer
You already installed it, checked it ...
Need to delete (it is installed as a user)
And find where the current is lying (you will help for example Link2SD) Then the APC file from which set to copy with the replacement (naturally the name should be the same) instead of the current ...
You make the reboot, then in the settings of the applications you are looking for the "Application Default" item or something like that and put the one that you installed as the main
And everything, check
You can easily put as a custom and via Lucky Patcher, Titanium Backup or Link2SD do a systematic and currently delete
And the same thing
