*Steps to reproduce:*

0. Set your Android phone display to sleep after 30 or 60 seconds.

1. Use Unity 2023.2 to create a new project using AR mobile Template 2.0. 

2. Build and Run on an AR-capable Android phone.

3. Point your phone camera North; follow the prompts in the Welcome UI to scan planes and place objects at the North end of the room. 

4. Continue pointing your phone North and do nothing until the screen sleeps.

5. Point your phone East; wake up the display. 

*Actual results:* 

The objects that should be in the North are now in the East (or wherever your camera pointed when you woke up the screen after sleep).  If you turn your phone North then the objects might jump to their original places, but if you look East again then the objects will jump there.  Basically ARCore seems confused about where the objects should be. 

*Expected results:* 

Spawned objects should remain in their original places after the screen sleeps and re-awakens. 

*Reproducible with versions:* 

Google Pixel 7 Pro and Samsung 23 Ultra

Unity 2023.2.10f1

*Can’t test with versions:* 

*Tested on (OS):* 

iOS and Android, deployed from Editor on MacOS. 

*Notes:*
* User Prevalence set as majority because I heard that Android install base is huge.  Feel free to retort if you have seen statistics favoring iOS.  I did not flag this as a regression, though I did not test this specific case for 1.0.  Contact me if follow-up testing would help solve this bug.
