I have a Galaxy S7 Active. Yesterday I received a notification on my phone that I did not recognize - a blue circle with a ghost inside of it and next to it the statement "Click me!! Click me!!" It seemed concerning and a person I trusted to know these things clicked it and it took him to a game center. Today I have the same icon with a different message. I don't want to click it as I do not know the source of these notifications. Can anyone help?
