Hi, can you try the branch in PR #4548 and see if that fixes it?

[dax72]

is there a dist ready to download?

I couldn't find any relevant changes on the Safari release notes:

I just tried on another iPad (iPad Pro 12,9""), v13.4.1...same problem! Motion sensor does not work when you click VR button.

We should probably disable cardboard / stereo mode on iPads

[dax72]

and on iPhone? currently I can confirm that it does not work on iPhone and iPad with iOS13.4.1.
VR mode on iPad has no sense..but on iPhone it's necessary

Got same issue, with my older iphone for tests with iOS 13.3 it does work properly, but newest 13.4.X it doesn't... as far as i checked DeviceMotionEvent.requestPermission() doesn't seem to work right, it asks about permission, right after with my app it reloads page and and my typical promise that checks if it's gyroscope or if the device support gyroscope it saying "false" for iPhone with newest iOS :/ previous version was ok.

Also checked with DeviceOrientationEvent, doesn't help :(

On iPad we can disable. On iPhone we can keep for now. What’s your audience? Can you share details on your application? We see Cardboard usage decline and harder and harder to come by. Polyfilled VR comes with a lot of issues like this one where things break when browser APIs and policies change.

[dax72]

We create VR games/apps for clients and they require iPhone compatibility

[dmarcos]

Is iPhone compatibility via Magic Window mode enough? Do you have any metrics of cardboard usage you can share?

[dax72]

Magic Window mode it's not enough, they need stereo mode.
I think the percentage of iPhone/cardboard is not relevant but clients require the compatibility iPhone/android and without it they do not market products.

Safari iOS from a development point of view is a nightmare because there is
no webVR/webXR support but for big companies it is not their problem, they want it to work on iOS too :(

[dmarcos]

@dax72 Thanks for the info. Is your client decision based on any audience metrics?

[dax72]

@dmarcos Unfortunately I don't have access to their audience metrics, but I have more clients that are asking to me to fix this iOS bug

[dmarcos]

@dax72 Are they willing to pay to fix the issue?
