How could we help here? You are providing ZERO information (code, manifest) about your app.

Try to reproduce it in a small project and upload it.

<supports-screens android:largeScreens="true"
    android:normalScreens="true"

That's normal. If you run a program compiled for debug without the IDE attached that's what happens. The IDE actually runs a lot of the code in debug mode - not the device,
