This is due to a change in Chrome m65 which breaks the Polyfill. See here for more info:

https://github.com/immersive-web/webvr-polyfill/issues/307 https://bugs.chromium.org/p/chromium/issues/detail?id=819413 https://bugs.chromium.org/p/chromium/issues/detail?id=796518 https://bugs.chromium.org/p/chromium/issues/detail?id=805146

The fix was merged a day late to make the M65 stable release, and unfortunately the fix ends up causing further issues (819413).

@dustinkerstein Thanks for the detailed info.

So my understanding is that there isn't anything we can do on the A-Frame side and everything will work again once M66 ships. I leave this issue open as a reference and as a reminder to verify M66 when available.

dustinkerstein commented 6 years ago

@dmarcos That's correct. It's a Chrome platform issue that was caused by an incomplete merge (796518 depends on 805146 but it wasn't originally planned for m65).

Also experiencing this on Oneplus 5. Vertical movement is extremely slow, horizontal barely works.

Chrome 65. Android 8.0.0 A-frame version 0.8.0

Works fine on iPhone.

Happens, after the Chrome update yesterday, on the Nexus 5X too. Yay. \o/

Chrome 65 Android 8.1.0 Aframe Version 0.8.0

Some more info on a separate but similar (and much more impactful) issue in Chrome M66:

They are changing the rotationRate units in the deviceMotion API from radians -> degrees to be in line with the actual spec. This is a good thing in the long term, but unfortunately, this is going break all existing Polyfilled sites on Chrome (including all A-Frame sites using a locally hosted library). It's already been addressed in the dev version of the Polyfill, which should find it's way into A-Frame soon, but it's going to be a bit of a mess once M66 goes stable. Here are the tickets where this change is currently being tracked:

Chromium - https://bugs.chromium.org/p/chromium/issues/detail?id=541607 Polyfill / cardboard-vr-display - https://github.com/immersive-web/cardboard-vr-display/issues/18

There's a tiny bit of hope that they decide to tweak how they implement this change (there's a suggestion about changing the spec so that it provides a "units" parameter) but most likely all Polyfill dependent sites will need to upgrade to support Chrome M66+.
