When I open my email it shows me a list of the emails in my inbox. But sometimes I get spam (or another message that I don't want to read) so I choose Edit and then check the box next to the message I want to delete. The problem is that as soon as I check that box, it opens the email, but I don't want it to open/preview the email at all. I just want to delete it. This doesn't happen on my iPhone 6+. Is there a setting I need to change to prevent this from happening?
