I have tried most of the code on stackoverflow but none of them are working.
I am using moto x4 for uploading picture using camera. when I use back camera it gets rotated 90 degree left and when I use front camera it gets rotated 90 degree right. but in debug mode, in both case I found the orientation = 0;

 else if (requestCode == CAMERA) 

 Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
 String imagePath = saveImage(thumbnail);

 File imageFile = new File(imagePath);
 ExifInterface exif = null;
 try 
 exif = new ExifInterface(imageFile.getAbsolutePath());
 catch (IOException e) 
 e.printStackTrace();
 
 int orientation = exif.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_NORMAL);
 bmap = GetandSetBitmap.rotateBitmap(thumbnail,orientation);


 mImageView.setBackgroundResource(0);
 mImageView.setImageBitmap(bmap);

This probably has to do with the fact that one camera is by default in landscape and the other in reverse landscape, so orientation = 0, as the orientation is detected to be the normal one in both cases. Unfortunately, I don't have a solution that wouldn't involve manually rotating the image to cover all cases. Personally I've used a switch to cater for the cases where my photo was saved with a 90 degrees rotation:

ExifInterface exifInterface = new ExifInterface(pictureFile.getPath());
 int orientation = exifInterface.getAttributeInt(ExifInterface.TAG_ORIENTATION, ExifInterface.ORIENTATION_UNDEFINED);

 Bitmap correctedBitmap;
 switch(orientation) 
 case ExifInterface.ORIENTATION_ROTATE_90:
 correctedBitmap = bitmap;
 capturedImageHolder.setImageBitmap(correctedBitmap);
 break;

 case ExifInterface.ORIENTATION_ROTATE_180:
 correctedBitmap = rotateImage(bitmap, 90);
 capturedImageHolder.setImageBitmap(correctedBitmap);
 break;

 case ExifInterface.ORIENTATION_ROTATE_270:
 correctedBitmap = rotateImage(bitmap, 180);
 capturedImageHolder.setImageBitmap(correctedBitmap);

 break;

 case ExifInterface.ORIENTATION_NORMAL:
 default:
 correctedBitmap = rotateImage(bitmap, 270);
 capturedImageHolder.setImageBitmap(correctedBitmap);
 break;

 
 } catch (IOException e) 

 

public static Bitmap rotateImage(Bitmap source, float angle) 
 Matrix matrix = new Matrix();
 matrix.postRotate(angle);
 return Bitmap.createBitmap(source, 0, 0, source.getWidth(), source.getHeight(),
 matrix, true);
 

In your case, you would need to detect if the photo is taken from the front-facing camera or the back and adjust the values accordingly.
