Orientation image image after use Front or Back camera

Question

i use camera in my app for capture image , when switch to the front camera, the picture is mirrorrd . i use this code for take picture (rotate and compensate the mirror) with this code Back camera is OK (without mirror and rotate)! but Front camera result be similar this picture :

this method for get Front camera id : (i use CameraInfo to get Front camera id and send id to result activity)

    public int getFrontFacingCameraId() {
        int numCameras = getNumberOfCameras();
        Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
        for (int cameraId = 0; cameraId < numCameras; cameraId++) {
            Camera.getCameraInfo(cameraId, cameraInfo);
            if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                return cameraId;
            }
        }
        return 0;
    }

this code for rotation : (use matrix)

private 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);
            return source;
        }
    }

and this code use in activity result :

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        switch (requestCode) {
            case PICTURE_RESULT:
                if (resultCode == Activity.RESULT_OK) {
                    try {
                        Bitmap thumbnail = MediaStore.Images.Media.getBitmap(getContentResolver(), IMG_URI);
                        Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
                        int rotation = this.getWindowManager().getDefaultDisplay().getRotation();
                        int degrees = 0;
                        switch (rotation) {
                            case Surface.ROTATION_0:
                                degrees = 90;
                                break;
                            case Surface.ROTATION_90:
                                degrees = 180;
                                break;
                            case Surface.ROTATION_180:
                                degrees = 270;
                                break;
                            case Surface.ROTATION_270:
                                degrees = 360;
                                break;
                        }
                        int displayOrientation;
                        if (cameraInfo.facing == getFrontFacingCameraId()) {
                            displayOrientation = (cameraInfo.orientation + degrees) % 360;
                            displayOrientation = (360 - displayOrientation) % 360;
                        } else {
                            displayOrientation = (cameraInfo.orientation - degrees + 360) % 360;
                        }
                        USER_CIRCLE_PHOTO.setImageBitmap(Bitmap.createScaledBitmap(rotateImage(thumbnail, displayOrientation), 480, 800, false));
                        getContentResolver().delete(IMG_URI, null, null);
                    } catch (Exception e) {
                        displayToast(this, "خطای گرفتن عکس:" + "\n" + e.toString());
                    }
                }
        }
    }

How can I fix the problem Thank you

and when change to this :

case Surface.ROTATION_0:
                                degrees = 0;
                                break;
                            case Surface.ROTATION_90:
                                degrees = 90;
                                break;
                            case Surface.ROTATION_180:
                                degrees = 180;
                                break;
                            case Surface.ROTATION_270:
                                degrees = 270;
                                break;

result :

back and for camera not OK!
