Answer 2

There you go :) working on 5X (7.0), MI3 (6.0), S3 Neo (4.4)

Intent launchIntent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA);
                            launchIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                            launchIntent.putExtra("android.intent.extras.CAMERA_FACING", android.hardware.Camera.CameraInfo.CAMERA_FACING_FRONT);
                            launchIntent.putExtra("android.intent.extras.LENS_FACING_FRONT", 1);
                            launchIntent.putExtra("android.intent.extra.USE_FRONT_CAMERA", true);
startActivity(launchIntent);
