you can use this demo in ios 12.2,you can drag screen by hand,but gyro is unuseful,if ios version <12.2,everything is ok
@1113 yikes it looks like they disabled gyro by default in 12.2 Apple to Limit Accelerometer and Gyroscope Access in Safari on iOS 12.2 for Privacy Reasons - MacRumors
You can turn it on in settings but unfortunately apple doesn’t prompt the user to do this.
If you want to detect if it’s supported you could try something like the following
var supported = false;
window.removeEventListener(“deviceorientation”, ()=>{
supported = true
});
setTimeout(()=>{
if(!supported){
// prompt user that orientation is not supported
}
}, 200)

Your QA have two way to resolve it,one is use the latest version of babylon,

two is handle the prompt,but i don’t know how to do it
