SPECIFIC ISSUE ENCOUNTERED

While walking continuously to use SLAM, ARCore's world Up started to go up and goes beyond the acceptable limit when the distance get increases(also Tested With AR Elements,HelloARController and some Measuring apps available in Google Play which using ARCore). I started an measure app to test this issue. I started to measure the mall while the phone is in front of front of my face camera facing the floor, When I complete my measurement, the phone is above to my head and facing the wall. That much world moved up. I have used ARKit to test the same Scenario. I haven't faced any issues in Up axis. I Know that you will say the same story that ARKit supporting less number of devices compared to ARCore but this I'm facing this issue even on your pixel phones. Please fix this issue soon.
