You can find real device dimensions with either using Display or DisplayMetrics

Using Display:

private void findRealSize(Activity activity)
{
    Point size = new Point();
    Display display = activity.getWindowManager().getDefaultDisplay();

    if (Build.VERSION.SDK_INT >= 17)
        display.getRealSize(size);
    else
        display.getSize(size);

    int realWidth = size.x;
    int realHeight = size.y;

    Log.i("LOG_TAG", "realWidth: " + realWidth + " realHeight: " + realHeight);
}

Using DisplayMetrics:

private void findRealSize(Activity activity)
{
    DisplayMetrics displayMetrics = new DisplayMetrics();

    if (Build.VERSION.SDK_INT >= 17)
    {
        activity.getWindowManager().getDefaultDisplay().getRealMetrics(displayMetrics);
    }
    else
    {
        activity.getWindowManager().getDefaultDisplay().getMetrics(displayMetrics);
    }

    int realWidth = displayMetrics.widthPixels;
    int realHeight = displayMetrics.heightPixels;

    Log.i("LOG_TAG", "realWidth: " + realWidth + " realHeight: " + realHeight);
}
