SSRS email subscription uses content-type that cannot be seen in mobile phones

Hello,

I used to have SQL Server 2008 and had subscriptions with a report exported to pdf attached. Email subscription with pdf attach. This was sent to some company emails, that could be seen in blackberry, iphone and Samsung mobile, and it worked ok.

I have updated sql to sql server 2014 with ssrs 2012, i did the same subscriptions to the same emails, and i can open them fine on the company desktops, but on the mobile phones(the same mentioned before) the attach can be opened. On the phones instead of the file name e get application/pdf.

I don't know if i should be doing something different or it is a problem from ssrs email construction.

Thank you
