@bialpio Android 8 is pretty old - is this a known Chromium issue?

[bialpio]

We should still work on Android 8. The fact that SceneViewer backend also does not seem to work is suspicious - can you confirm that any other ARCore-powered app is functional, just to rule out some ARCore issue?

Hi there, even I was wondering so I got my hands on that device.

ARcore Element App too was black screen. So I did the diagnostic and found the Sensor Hub not working.

It's a hardware issue

However I came across Oppo F21 Pro 5G with same issue. I'll get the device in my hand shortly.

@elalish Shall I open a new issue for Oppo F21 Pro 5G?

[elalish]

No, let's keep all the details here. I need to find the right person to assign this to.

facing the same issue on my samsung A54 5g with latest chrome browser on android, the AR viewer gets stuck while showing "AR Not tracking" and crashes.
