Can't find android app

I’m trying to install one of the scenes in the mobile assets package. I’ve installed the SDK manager and downloaded all the api packages. I already configured all the settings in unity so the game will be built on the phone. It takes a minute, but after it finishes building the game, I can’t find it, or any sign that unity has made any changes to the phone. Please help, my phone is an LG G2

If you select “Build and Run” the app should automatically launch on your phone after the building is done.

If you don’t do Build and Run you have to manually copy the APK onto your phone, then install it via a File Manager.
