Ron wants to know if you can set Outlook to be the default email app on his Samsung Galaxy S7 phone. Leo says that there's a section in the phone's settings where he can choose default apps. It will depend on whether or not Samsung allows it, though. If it was a pure Android phone like the Nexus, then it's definitely possible. If he can't choose it in the default apps, he can always use Nova Launcher in the Google Play store. It'll let him set up his phone the way he wants.
