In my react native app. Video call is working fine when the app is in foreground. But If i put my app in background or screenlock, there is black screen for 5-6 seconds after I open the app.
I want to know if the black screen be fixed, or atleast detected.
Black screen is also coming for the first 3 or 4 seconds when the video connection is established.

That’s because the WebRTC connections are discovering and connecting again. It takes a little bit to handle all the connections again, that’s way the blackscreen appears.
Sadly, this is a limitation which can no be fixed easily, because the app is connecting to all the streams again.
I suppose that this is a react native error which put the app to “sleep”. I don’t know much about React Native, but there should be an API to keep your app running while in background or something to avoid this issue.
