Spatial tracking in AR not working on Xiaomi 13T

[Bastel-Bodo]

SPECIFIC ISSUE ENCOUNTERED

When trying to use any AR app that's based on ARCore on the Xiaomi 13T, the spatial tracking in the AR experience is not working. The virtual objects are drifting heavily all over the place, rendering the application unusable.
This can be easily reproduced using any WebXR-based experience.

VERSIONS USED

• Device Manufacturer, model and OS: Xiaomi 13T, HyperOS 1.0.2.0.UMFEUXM
• CPU: Dimensity 8200-Ultra
• Android version: 14 UP1A.230905.011
• Google Play Services for AR (ARCore): 1.41.233110993
• Output of adb shell getprop ro.build.fingerprint: Xiaomi/aristotle_eea/aristotle:14/UP1A.230905.011/V816.0.2.0.UMFEUXM:user/release-keys

STEPS TO REPRODUCE THE ISSUE

1. Open the WebXR homepage on the device: https://immersiveweb.dev/
2. Launch the demo AR experience using the "ENTER AR" button
3. The AR experience will launch, and it is possible to find the "WebXR!" demo object in space. However, it doesn't stay in place and drifts around uncontrollably.

Alternatively, it is also possible to use any app from the Play Store that uses ARCore; the result is the same.

I'm encountering this exact same issue as well.

Bought my 13T a week ago, installed Unity and was going to try some AR dev... EXACTLY this problem :/

I am experiencing the same thing as you where ARCore is not working optimally on the 13T device. I checked for gyroscope, magnetometer, accelerometer, orientation, everything is running normally on this device (I used the Sensor Test app on the Play Store). However, when used for Augmented Reality applications, the position of the device drifts uncontrollably.

This can be seen from my video below, where I tested with the Depth Lab application made by Google as well. I tried on my other Android device (Realme 9), it runs normally, unlike this 13T device.
