Instantiated Prefab instantiates upside down sometimes?

Scripting
1

When I’m looking forward the prefab instantiates correctly facing me the camera on hololens.
When I turn around the instantiated prefab appears upside down when instantiated?

This loop runs every 6 seconds.
How can i fix that so it always appears right side up?

Vector3 camPos = Camera.main.transform.position + Camera.main.transform.forward; tempNumber = Instantiate(ScaryFace) as GameObject; tempNumber.transform.position = camPos;
yield return new WaitForSeconds(1.0f);
Destroy(tempNumber);

Normally you should do this: public static Object Instantiate(Object original, Vector3 position, Quaternion rotation

For example:

Instantiate(PointerLineSprite, TapLocation.position, Quaternion.identity);
