My 8gb tablet has no memory left. I have an SD card and tried to move the app to it but it's disabled (is that the case for you Androids?). I'm running 4.2 I believe. Is there a way to move the app or at least the cached files to the SD card?
Start the app.. go to camera and hit the four dots icon in the top right corner. At the bottom of the window that opens should be a section titled VIDEO CACHE. Only 2 options and a manual clear cache button
