I have a samsung M32 mobile. When i used the API level 30 app then i found that camera and microphone not work in samsung phone at a time join meeting error is: "webcontentsdelegate::checkmediaaccesspermission: not supported"
When i used API level 29 app then both camera and microphone access in the meeting.
When i open the meeting in Chrome browser app install then same problem face. Camera and Microphone not access.
I also check this in Samsung other Android 11 phones 2 more models A22 and F22 and same error show.
When i check this in Pixel 4a (Android 11) phone then their camera and microphone work fine in API level 30 app.
I also raised the issue in google web view team. But with same webview version camera and microphone work in Pixels 4a and not work in Samsung android 11 version.
