I got an email (MS Exchange 2010 / Native Mail App / LG G2 - 4.4.2 / connection->mobile-data[HSDPA]) with an PDF file with a size of ~18 MB. When I click on it, it is trying to download it. After one second I got a message " was not downloaded".
When I am trying on an iPhone 5 (iOS 7.1) I can download and open the file.
Any work arounds or fixes for that issue?
