Galaxy 25+.... I am experiencing pop up ads that overlay any app that I have open or am working with. This includes Google, messenger, fb, texts, etc. Usually an avg of three ads. Sometimes they clear easily, other times they block th display and are difficult to clear. Seems this started with the appearance of three small purple balls on the screen followed by the ads (see photo) Verizon protect and Malware has not found anything. Verizon techs observed the event and tried some changes in settings, but it did not help. This has become very annoying. Anyone else? Solutions? Thanks in advance
