Photo rotated from camera (SAMSUNG device)

Question

i hate this company. All them devices have a lot of bugs. Ok question : Im trying to fix stupid problem (which as i know exist more than 5 years) Its photo taken from camera - rotated on 90 degree. I have two devices :

  Nexus 5p and Samsung j2  
  Nexus - work perfect. Everything fine. 
  Samsung - photo rotated

For example :

Photo size - nexus : Portrate : width 1000, height 1900.  Landscape :
width 1900 , height 1000

Lets see on samsung device :

Photo size  - Portrate: width 1900(?????) height - 1000(????)
rotate to landscape : width 1900 height 1000

After some testing : if make photo in landscape mode on samsung device - than everything ok. Photo not rotated

If make photo in PORTRATE - photo rotated on 90 degree. (BUT size of photo as on landscape (HOW ITS POSSIBLE) ?

Anyone know how to fix this stupid bug ? Maybe any can tell me how to detect orientation for camera ? Im using IntentActivity for photo :

String _path = Environment.getExternalStorageDirectory()
                                    + File.separator + "camera_img.jpg";
                            File file = new File(_path);
                            Uri outputFileUri = Uri.fromFile(file);
                            Intent intent = new Intent(
                                    android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                            intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
                            startActivityForResult(intent, CAMERA_REQUEST);

Any help ? I also add a checker , if its samsung device than rotate. But rotation good only if we create photo in portrate mode. In landscape everything fine. So i need somehow detected in which orientation photo was created. Any one know ?

UPD 29.08.2018 I found that this method doesn't work with Samsung device based on Android 8+. I don't have Samsung s8 (for example) and can't understand why this again does not work there. If someone can test and check why this not work - let's try to fix this together.

I found how to fix: well it's really stupid and very hard for me.

First step get activity result

 @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {

            String _path = Environment.getExternalStorageDirectory() + File.separator + "TakenFromCamera.jpg";
            String p1 = Environment.getExternalStorageDirectory().toString();
            String fName = "/TakenFromCamera.jpg";
            final int rotation = getImageOrientation(_path);
            File file = resaveBitmap(p1, fName, rotation);
            Bitmap mBitmap = BitmapFactory.decodeFile(_path);

Main steps it's getImageOrientation before changes in file.

1. getImageOrientation (by path)
2. resave file (if need send to server, if you need only for preview we can skip this step)
3. get correct bitmap from file

For preview it's enough to perform only steps 1 and 3, and using this function - just rotate bitmap.

private Bitmap checkRotationFromCamera(Bitmap bitmap, String pathToFile, int rotate) {
        Matrix matrix = new Matrix();
        matrix.postRotate(rotate);
        Bitmap rotatedBitmap = Bitmap.createBitmap(bitmap, 0, 0, bitmap.getWidth(), bitmap.getHeight(), matrix, true);
        return rotatedBitmap;
    }

getImageOrientation

public static int getImageOrientation(String imagePath) {
    int rotate = 0;
    try {
        ExifInterface exif = new ExifInterface(imagePath);
        int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, 1);
        switch (orientation) {
            case ExifInterface.ORIENTATION_ROTATE_270:
                rotate = 270;
                break;
            case ExifInterface.ORIENTATION_ROTATE_180:
                rotate = 180;
                break;
            case ExifInterface.ORIENTATION_ROTATE_90:
                rotate = 90;
                break;
        }
    } catch (IOException e) {
        e.printStackTrace();
    }
    return rotate;
}

and resaveBitmap if need

private File resaveBitmap(String path, String filename, int rotation) { //help for fix landscape photos
        String extStorageDirectory = path;
        OutputStream outStream = null;
        File file = new File(filename);
        if (file.exists()) {
            file.delete();
            file = new File(extStorageDirectory, filename);
        }
        try {
            // make a new bitmap from your file
            Bitmap bitmap = BitmapFactory.decodeFile(path + filename);
            bitmap = checkRotationFromCamera(bitmap, path + filename, rotation);
            bitmap = Bitmap.createScaledBitmap(bitmap, (int) ((float) bitmap.getWidth() * 0.3f), (int) ((float) bitmap.getHeight() * 0.3f), false);
            bitmap = Utils.getCircleImage(bitmap);
            outStream = new FileOutputStream(path + filename);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 100, outStream);
            outStream.flush();
            outStream.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
        return file;
    }
