Hi @tristanbob and thank you for taking the time to look into solutions for this! The solution you found seems to be supported by Safari on iOs only (https://developer.mozilla.org/en-US/docs/Web/API/DeviceMotionEvent#browser_compatibility) CanIUse is more optimistic though: https://caniuse.com/?search=requestPermission

I wonder if this issue occurs on Android smartphones as well. Do you have a game example that I could use to test on my Android?

[tristanbob]

@AlexandreSi there are a couple game examples already inside GDevelop that you can test with. Search for "device sensor".

The external example I linked to worked on my Safari and Chrome browser, so it feels like it should work for most users.

Any updates on this? I'd love to make games with this feature.
