Hi, I have already commented [here](https://forum.babylonjs.com/t/zero-touch-response-on-ipad-7-2019-i-did-all-the-known-solutions/11038/30), but being an old thread I thought maybe it would make sense to create a new one. I am experiencing no rotation with `ArcRotateCamera` (but probably the problem isn’t camera type specific), using Iphone7 IOS12 . I know from a fact that Iphone7 with IOS14 works, and Iphone8 with IOS13 works too. Looking at [this PG](https://playground.babylonjs.com/#PI1KKW) getting `mouse` and no rotation seem highly correlated. I have no idea what I could do to tackle this. Can anybody help? I am referring to ‘rotation’ because being on BrowserStack that’s all I can check, but I am pretty also 2 fingers gestures are affected. Thank you ---

Let me see if I can check on simulator … ---

Hi @Cedric, I have tried having a look 1. Iphone IOS12 does not have `window.PointerEvent` nor `navigator.pointerEnabled`, so `BABYLON.Tools.GetPointerPrefix()` returns ‘mouse’ [Babylon.js/tools.ts at bfdfdab7a13bd22915c0eca320f08a61cb560d8d · BabylonJS/Babylon.js · GitHub](https://github.com/BabylonJS/Babylon.js/blob/bfdfdab7a13bd22915c0eca320f08a61cb560d8d/src/Misc/tools.ts#L300) 2. Even adjusting for that, `Pointer` events in IOS12 seem to be ‘touch’ prefixed, rather than ‘pointer’, so the events attached via `DeviceInputSystem._handlePointerActions` that use prefix from `GetPointerPrefix` won’t fire. [Babylon.js/deviceInputSystem.ts at bfdfdab7a13bd22915c0eca320f08a61cb560d8d · BabylonJS/Babylon.js · GitHub](https://github.com/BabylonJS/Babylon.js/blob/bfdfdab7a13bd22915c0eca320f08a61cb560d8d/src/DeviceInput/deviceInputSystem.ts#L534) I used [this](https://codepen.io/undefinederror/pen/gOLjZxx?editors=1111) to check the event name. I get ‘pointer’ on IOS13 and above and ‘touch’ on IOS12 and below. So I tried making a small change in `GetPointerPrefix` via Gitpod ```auto if (eventPrefix === "mouse" && hasTouchend) { eventPrefix = "touch"; } return prefix; ``` And now in Playground I get this error ☹ ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/0/05575891aa1b5ebd19cb51cd5eba07b367a0b39e.png) ![image](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/2X/0/058f4e158c45064a6e872ff47b66917f6abf731b.png) I am testing this in BrowserStack, and breakpoints don’t work. I don’t think I can manage to do much more than this.

That’s far beyond my knowledge on input. Pinging @PolygonalSun ---

@PolygonalSun (or whoever is willing and able) Any chance you could give me a hand with this? ---

Hey @PolygonalSun, have you figured out anything? Sorry if I insist, but it is unfortunately imperative for us to support IOS 12 in our Babylonjs project. Let me know if you have any news. Thank you ---

So here’s what I’ve got so far. If the event is being treated like a TouchEvent, rather than a PointerEvent, this would explain the error. First, we track all touches with pointerId, which TouchEvent doesn’t have. The biggest issue that I’ve been encountering is finding a way to debug this, as I don’t have a device with iOS 12. The best way that I could think to fix this would be to find a good way to identify when dealing with TouchEvents and then have a proper way to assign and track their ids, as though they were pointerIds ---

Hey @PolygonalSun, Thank a lot for looking into it. I think I solved it! 🥳 Importing [pepjs](https://www.npmjs.com/package/pepjs) (Pointer Events Polyfill) seems enough get pointer events going This PG works for me on IOS12 and even 11 (browserstack) [https://playground.babylonjs.com/#PI1KKW#10](https://playground.babylonjs.com/#PI1KKW#10)
