Nothing came up that has helped me in my search to fix this problem. I deal with word, excel sheets etc through email. I have never had a problem with this in the 11 months of owning this phone until today. I go to open an email with a word attachment and when I open the email it it says it's an unsupported file type. I pulled sd card and battery after shutting off my phone. Dled new free versions of office apps, no luck anywhere. I've ben using quick office btw which came with the phone.
