Hey all. Trying to figure out why I can't open file attachments from emails. Received some pdf files and two doc files today. Tried opening files from email with pdf reader program and quickoffice or whatever its called. Neither type of file would open. Tried to download then open files with same problem. Files are definitely .pdf and .doc, just opened and rad them on laptop now. Also confused...is there any way to look at my SD card folders and files through a phone app? Can't figure out how to see anything other then my music and photos. Thanks for any input.
