As the title implies... I sometimes change from photo to video mode (or vice versa) and my live feed becomes pixelated and digitized. Is that an app issue? My photos/video are unaffected; I tried taking a picture/video when this happens. I switch back to either photo/video mode and the live feed goes back to normal, sometimes it takes a couple switches back and forth to reinstate the live feed. I am using a Nexus 7 2012 tablet - is that the issue? I side-loaded the APK outside of the Google Play Store.
