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

In my Unity 4.6.1f1 i have similar problem, i cant build on my Android device, application starts with a “black screen”. This is a problem with Unity versions, please update to patch version.

Unity Path Version
