I have a Galaxy S7 and can launch an app from the widget, but cannot find the application icon to delete the app I have a Galaxy S7 and can launch an app from the widget, but cannot find the application icon to actually uninstall the app.  Any thoughts?
If you go to your Settings app, and find the Apps or Application Manager. This will show you a list of all the apps installed on your phone.

Another way to do this is to download an app that triggers the app uninstaller for you (e.g. Uninstaller or Easy Uninstaller App Uninstall). When you download one of these apps it should list all of the apps on your phone, for you to remove one or more of them at once.

Hope this helps
