Hi, I’ve a problem with my solution. I receive a “DOMException: Could not start video source” error on some android phones. I don’t know why! And only if I try to use rear camera! front camera works well!  
I use chrome and have android 9 (samsung Galaxy S8)  
Here my code (the error appens when I call “await session.publish(publisher)”):

```
			logger.info("[create settings]");
			const publisherSettings: PublisherProperties = {
				videoSource,
				audioSource: true,
				publishAudio: true,
				publishVideo: true,
				frameRate,
				resolution: resolution,
				mirror: false,
			};
			logger.info("[settings created]" + publisherSettings);
			const publisher: Publisher = this.OV.initPublisher(
				undefined as any,
				publisherSettings
			);
			logger.info("[start publishing]" + publisherSettings);
			await session.publish(publisher);
			logger.info("[published]" + publisherSettings);
			const data: IConnectedSession = {
				mainStreamManager: publisher as StreamManager,
				publisher,
				publisherType,
				isConnected: true,
			};
```

Test with other videoconference web pages to see if behavior is the same. Maybe you have some issue with chrome not related with OpenVidu.
