I would avoid anything that starts with .com, anything you clearly cannot identify, or unsure of. Of course, if you have anything from say, Yahoo, I would disable that.
Thanks. Yeah, I disabled all the Yahoo stuff. Some of the Samsung stuff (don't use the sharing apps).. but not sure if I went too far or not far enough. WHen I had my GS3, there was a list in the forum of the apps/processes that could be disabled. Was hoping there was one floating around for the s4.
