I'm new at this and, at first, my Galaxy S7 worked plug and play as advertised. Then, I started exploring Cardboard Enabler and apps from the Play store. I couldn't get any of them to work since the home button would depress when the phone was snapped into place most of the time and there was a double image the rest of the time. So, I uninstalled the new apps.....now, Gear VR won't start when I insert my phone. I'm just looking at my phones home screen through the lenses. Could someone please give advice here?
