Some applications provide shortcuts (long-press on the app-icon). These icons sometimes do not have the right icon. It's gray or it's the default Android icon.See: Can this be fixed? I don't want to use another 3rd party launcher.
I'm using the smart button. Pushing twice opens camera app.I'm also using face unlock.Pressing the smart button twice wakes up the phone and should start the camera app.Instead, it recognizes my face and goes to the home screen.
