Can you verify that the RN device supports the codecs for the room? The supported codecs are returned in the onLocalParticipantSupportedCodecs callback. See https://www.twilio.com/docs/video/managing-codecs for how you might want to set up the room depending on the platform of the participants.

Hi 👋🏼, how did you handle solving this problem? I have a similar problem, but on the other side (the web application) I can't see what the Android device's camera transmits, however, I can hear it. With iOS it works fine.

You need to add a line preferredVideoCodecs: ['VP8'] in 'Video.connect
