Okay So I read an article about some emulators apps were removed from the google play store cause they might be malware. So i checked my apps and one was removed from the app store. It was called Retro Gen Plus. So i figured whatever. I never play games on this phone anymore anyways. So i uninstalled the app. Then I checked my samsung files and it still had a file. Labeled retrogen. So when I got back to the main screen. There was a little green andriod robot icon with no name, it had no app info and the other option was disable. i quick googled something that said to clear the cache but never really explained what the icon was. Well it did disappear when I did this. I just was wondering if any one knows what that green icon was?
