Answer 1

So, here is my solution.

private int getCurentOrientation() {
    Display d = ((WindowManager) getSystemService(WINDOW_SERVICE))
            .getDefaultDisplay();
    boolean isWide = d.getWidth() >= d.getHeight();
    switch (d.getRotation()) {
    case Surface.ROTATION_0:
        return isWide ? ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
                : ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
    case Surface.ROTATION_90:
        return isWide ? ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE
                : ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
    case Surface.ROTATION_180:
        return isWide ? ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
                : ActivityInfo.SCREEN_ORIENTATION_REVERSE_PORTRAIT;
    case Surface.ROTATION_270:
        return isWide ? ActivityInfo.SCREEN_ORIENTATION_REVERSE_LANDSCAPE
                : ActivityInfo.SCREEN_ORIENTATION_PORTRAIT;
    }
    return -1;
}

private void lockOrientation(boolean lock) {
    if (lock) {
        setRequestedOrientation(getCurentOrientation());
    } else {
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_FULL_SENSOR);
    }
}

On 4 devices (2 smartphones and 2 tablets) it works as nedded.
