When i look at the Recents list in the Phone app I can see that some are marked as spam and/or blocked but a number of them are not. How can I mark a call as spam or blocked in my Recents list ? If I choose a recent call the only choices that I see, beside the phone icon for calling back, are "Add contact:, "Message", and "History". Surely I should be allowed to mark a recent call as spam or as a number which should be blocked.
