I have a very simple question: My impression is that gmail decides whether to send an email you receive to your inbox or to spam, and that decision is implemented in the exact same way whether you view your emails on a PC or on a smart phone. In other words you, the user, can't control the decision gmail makes, you can't have a person's emails sent to your inbox on your PC but to spam on your phone. That could never happen, either deliberately or inadvertently, am I correct?
