orientation tablet vs phone

所以我剛剛測試了一個應用程序，我一直在三星平板電腦上測試電話設備。orientation tablet vs phone

基於accelermoter數據的應用程序更新的圖形和我注意到，在平板電腦上是治療的風景與人像..其自然人像模式設備上很好..

任何想法，我哪有那麼它ajust這適用於兩個：

public class ARLaunch extends Activity { 

/** Open Camera View **/  
private CamLayer camPreview; 
/** Open Camera View **/ 
private GLLayer glView; 

private WakeLock mWakeLock; 

/** Called when the activity is first created. */ 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    // requesting to turn the title OFF 
    requestWindowFeature(Window.FEATURE_NO_TITLE); 

    // making it full screen 
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, 
    WindowManager.LayoutParams.FLAG_FULLSCREEN); 

    //Set Screen Orientation 
    this.setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 

    try{ 
     final PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE); 
     this.mWakeLock = pm.newWakeLock(
       PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "My Tag"); 


     //Create Intance of Camera 
     camPreview = new CamLayer(this.getApplicationContext()); 

     //Create Instance of OpenGL 
     glView = new GLLayer(this); 

     //FrameLayOut for holding everything 
     FrameLayout frame = new FrameLayout(this); 
     // set as main view 
     setContentView(frame); 

     // add Camera to view 
     frame.addView(camPreview, new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT)); 

     frame.addView(glView); 



    } catch(Exception e){} 
} 
/** Remember to resume the glSurface */ 
@Override 
protected void onResume() { 
    super.onResume(); 
    try{ 
    this.mWakeLock.acquire(); 
    } catch (Exception ex){} 
    glView.onResume(); 
    glView.setZOrderOnTop(true); 
} 
/** Also pause the glSurface */ 
@Override

    super.onPause(); 
    try{

    glView.onPause();
