On some devices (specially Samsung) I have found the following error while establishing a P2P connection:

Error processing ICE candidate- Failed to set remote offer sdp: The order of m-lines in subsequent offer doesn't match order from previous offer/answer

If I establish the connection for the first time it works perfectly but if I try it a second time it fails until I wait some time, even if I force the P2P connection to close. This does not happen with Chrome for Android or every device.

My code before setting an Ice candidate:

    var candidate = new RTCIceCandidate({
        sdpMLineIndex: evt.sdpMLineIndex,
        sdpMid       : evt.sdpMid,
        candidate    : evt.candidate
    });
    peerConn.addIceCandidate(candidate, onSuccess, onFailure);

It seems that I wasn't cutting the local stream properly which made the camera and microphone look like they were still in use. 

 if(localstream){
        localstream.getTracks()[0].stop();
        localstream = null;
    }

I think Samsung's layer makes Firefox act differently as it only happened on the Samsung devices from all the devices I tested.
