Great S7 port. Just installed and noticed that the "Sort" function in "Contacts" doesn't work. I tried to toggle between sort by last name and first name and it doesn't do anything. Also tried to change the "name format" from first,last to last,first, and nothing happened.
Dominion settings also has a bug: Under "statusbar settings" toggling the "stock battery" option doesn't hide the stock battery.
Also, I don't think Call Recorder (under Dominion Settings) is working for both incoming and outgoing calls.
I'm not sure what could be going on with your contacts as I don't have that issue. For the battery, make sure you have 3minit toggled on. Toggle the stock battery to show, then back to hide, and then reboot your phone. See if that helps.
