In the dev version of my app, I can hold down 4 fingers, bring up the command line, and change the r.MobileContentScaleFactor on Android. When I put the same commands into iOS, it does not seem to work. Is there another way to change resolution in game? I want to have a graphics settings menu and let users change their resolution in game. I understand I can set the resolution inside of the UE4 editor, but I want to let users do it themselves as well.
