I'm on KK and haven't received an update to Lollipop. I know KK changed the write permissions for the SD cards and there is a fix if you have root. I don't want to root as I'm waiting for the Lollipop OTA. When I tried to use the microSD card for the camera app it tells me the card is full. The card shows 31.72gb free in storage though. I tried copying files to the card with a 3rd party app, which of course did not work. Also I see no way to copy files to it using the default file manager. In KK Samsung allowed the camera to write to the card and the default file manager. Did LG not build that in? It has no problem reading the video and audio I have on the card.
