Hi,
I have developed an Android APK combined to Krpano "engine" which uses Webview feature to manage VR tours.
Since last year, it was running perfectly on Nexus/Lollipop 5.0 and Samsung S7/Mashmallow 6.0.
Since last Samsung S7/Nougat 7.0 upgrade, it seems that Webview no longer supports gyroscope...
Of course, as short term solution (I hope), like in my fisrt APK version, I call external web browser but it is less efficient.
Can someone else confirm?
