I have a samsung s5. Unfortunately, whatapp pictures and videos go to the internal memory. Astro file manager is not able to move them to the Sd card. So the internal memory fills up very quickly. I then have to manually move them to my desktop, The videos are too big to send by text, How do others do this? Is there an app that works better? Or is there an app that will move photos and videos from the internal memory to the SD card? Thanks for your advice!
