[Randyf1963]

#$&@ ? I downloaded an apk that was supposed. to be the final upgrade for an app I wanted. I thought it included the whole app and installed it. Nothing happened I went to Google play and the app wasn't listed ! @#$&( ! Now I'm not happy about that but I'm even less happy about all the damn popups ! I can't do anything without one showing up ! Can someone give me a hand please ?.i have a galaxy S 7 Active .. I will be searching myself for answers.
Now how do I follow this post to see the responses ? I m pretty new here .. thanks all !

1. Uninstall the app. Go to Settings>Apps>Look for whatever it is you installed.

2. Don't download apks from random sources. Only from the developer's site if they have it, or. Google Play.
