Reading mail if I select more that 1spam message the program remives the Spam select option but leaves the useless "add star" feature. Obviously people who design this mail client don't use it the way the public does but I have found this true of most Samsung software. I guess they did not learn when the dumped SD card slots and no one bought that years phones or the cumbersome useless Bixby button and one more voice command no one uses.
So just keep in mind that whenever you use your email, you'll likely receive spam because most things requiring emails will sell your personal information. So if you go to the bottom and unsubscribe you'll stop receiving their emails. However, it's a hard lesson that some just don't learn! Don't give out any personal information.
