I set World Center Mode of Vuforia AR Camera object in scene to DEVICE_TRACKING to apply handheld device rotation to AR Camera object, it works fine and when I look around by my android mobile phone the Vuforia AR camera move in the scene too. I set my location markers (Point of Interests) in their location in unity scene where x = latitude and z = longitude and set AR Camera transform.position to Input.location.lastData on each frame so when user move in real world the AR Camera also moves in unity scene. My problem is here : Each time I run the app my markers have different position in real world when they should be static in the same coordinates.
How can I fix this?
I'm using a Samsung Galaxy S7, so I have gyro.
