In Gmail I'm getting "SD card required to download attachment" when I ask to Preview. When I click download I can view it but it then saves it to my Gallery. This just started happening a few day ago.
Also all of my mail had been going into the All Mail label, on my phone not on the web. I cleared data, Cache and did a battery pull and that seem to fix that issue. I couldn't tell if it created the other problem or if it was already there.
