    Finally after struggling for three days, I have devised a simple mechanism to overcome the Samsung S3 Saga.

    Below is the code, a quick summary of the code is that I first check the Manufacturer of the device and based on this I call different intents for camera.

    public class MainActivity extends Activity {
    
        private static int RESULT_LOAD_IMAGE = 1;
        private static final int PICK_FROM_GALLERY = 2;
        int CAMERA_PIC_REQUEST = 1337;
        Bitmap thumbnail = null;
        private static final int OG = 4;
    
        private static final int CAMERA_IMAGE_CAPTURE = 0;
        Uri u;
        ImageView imgview;
        // int z=0;
        String z = null;
        byte b[];
        String largeImagePath = "";
        Uri uriLargeImage;
        Uri uriThumbnailImage;
        Cursor myCursor;
    
        public void imageCam(Bitmap thumbnail) {
            Bitmap photo = thumbnail;
            ByteArrayOutputStream bos = new ByteArrayOutputStream();
            photo.compress(Bitmap.CompressFormat.JPEG, 70, bos);
            b = bos.toByteArray();
            ImageView imageview = (ImageView) findViewById(R.id.imageView1);
            imageview.setImageBitmap(photo);
        }
    
        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            Button bt = (Button) findViewById(R.id.button1);
            bt.setOnClickListener(onBTN);
            if (savedInstanceState != null) {
    
                Bitmap Zatang;
                String B1 = savedInstanceState.getString("message");
                Toast.makeText(this, "SavedYeah" + B1, Toast.LENGTH_LONG).show();
                BitmapFactory.Options opts = new BitmapFactory.Options();
                opts.inSampleSize = OG;
                Zatang = BitmapFactory.decodeFile((B1), opts);
                System.gc();
                if (Zatang != null) {
                    Toast.makeText(this, "Success Zatang" + B1, Toast.LENGTH_LONG)
                    .show();
                    imageCam(Zatang);
                }
            }
        }
    
        private View.OnClickListener onBTN = new View.OnClickListener() {
            public void onClick(View v) {
                openNewGameDialog();
            }
        };
    
        String[] B = { "Cam", "Gallery" };

                        if(BX1.equalsIgnoreCase("samsung")) {
                            Toast.makeText(getApplicationContext(), "Device man"+BX1, Toast.LENGTH_LONG).show();
                            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                            startActivityForResult(intent, CAMERA_IMAGE_CAPTURE);
    
                        } else {
                            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); 
                            startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST); 
                        }
                    } else if (i == 1) {
                        Intent intent = new Intent(Intent.ACTION_PICK);
                        intent.setType("image/*");
