[AC Question]

I found that I have a ton of space being used up on my phone due to every email attachment that I ever opened was automatically saved on the phone. I don't want to have to keep going in and deleting these attachments (many of which I do not need saved). How can I view them (what app?) and decide if I want to save them myself? These attachments are any of these: pdf, word document, excel file, etc.

Which email app are you using?
Different apps have different options for handling attachments.
Many times these options are groups together regarding mobile data vs wifi connections.

If you try to view the attachment, obviously it needs to be downloaded to the phone first.
If you don't need to view the attachment, the email app might have an option to not download it.
