I can open most files on my Tab 2, however this one particular client of mine sends PDF's through daily - none of which open on my Tab. They're small files - 100k approx. They open perfectly on the iPad and on my PC, just not on the Tab. When they come through on email, I save them to the device and then go to open them, but receive a message telling me that no application can open the file. It's a standard PDF doc, and I can normally open any other PDF's just fine on the Tab. I have Kingsoft Office and Adobe Reader installed on the Tab - both of which I normally use to view PDFs and have no issues - with the exception of this customer's PDFs. It's definitely not a problem with the files since they open perfectly on other devices. Strange thing is these particular files don't open on any of our office Galaxy Tab 2's (so it's not just my device). Any idea what the issue could be? Cheers!
