Carlette clicked on something in her Samsung Galaxy S5 mobile device and now she's getting popups. What can she do? Leo said to go through the apps and see if there's anything she doesn't recognize. Uninstall those apps. What she can do is go into Google Play and sort apps by date installed. The one she installed recently is probably the one that is causing the popups. In fact, install as few as possible. If that doesn't stop it, she may need to completely reset the phone to factory settings. That'll reinstall the OS.
