"I'm not sure what kind of browser comes on the Samsung Gear S3, but maybe it doesn't support suspending the audio context? If you check in the browser console on the device if AudioContext.prototype.suspend is available, that would identify the issue. If the browser doesn't support suspending or resuming the audio context, the problem is with the browser, not C2 - C2 will use these to optimise battery life if they are available, but if they're not available there's not much choice other than to leave the context running idle in the background. "
So there are the question:
1. what kind of browser comes on the Samsung Gear S3 S2?
2. Is it support the audio context?
3. How can it be checken with emulator or how? I mean see it in Logs "if you check in the browser console on the device if AudioContext.prototype.suspend is available, that would identify the issue"?
