I have a 16 GB SD card installed in my Ellipses 7 Tablet. I had no problem copying picture or video files over to the SD card to keep the on board memory free. Now with this Kit Kat upgrade I cannot move these files. I get errors. I'm using both ES File Explorer and X-plore file manager and neither will work. I can create a folder so I know I'm writing but can't copy files. I've reformatted the SD card and tried everything else I can. I have read this is prevented in Kit Kat. I would not have upgraded had I known however I have an LG G3 with Kit Kat and have no problem copying files. Neither the G3 or the tablet are rooted. If it's Kit Kat why is it working on my G3 and not the Ellipses. If it is Kit Kat, Is there a work around?
