It's for verification purposes, sanity check, and note keeping if a related issue comes up in the future. Please provide the specific versions from your lock file.

In my app I use following versions: @livekit/react-native: 2.6.2 livekit-client: 2.9.5 @livekit/react-native-webrtc: 125.0.9

In example app I see different versions: @livekit/react-native: 🤷 livekit-client: 2.9.8 @livekit/react-native-webrtc: 125.0.8

Bug occurs in both of these apps

Fixed in 2.7.6.

WARNING: This was "fixed" by completely removing the ability to switch camera through applyConstraints (and _switchCamera which uses this internally).

This is a breaking change! And documentation keeps incorrectly suggesting to use applyConstraints.

The only working solution now is to rerequest stream with new constraints
