Hi All - I am using the native samsung email client configured through MDM. When I click on attachments and choose either preview or download it just sits at zero percent. I never receive an error. I have 4.2.2 and a Verizon S4. We have seen this issue on a few Galaxy devices world wide. I have checked all the defaults and I do not see anything for the email client. We are using MDM and controlling aspects of attachemnts. Typically it is opened in then thinkfree attchment viewer.
