microphone – The camera does not record with external microphone since the last update

I have a Galaxy s9. Since I updated on November 15, when I record a video with my external microphone, sometimes I use the internal microphone of the phone. When the microphone is connected, it says it uses an external microphone to record, but it does not.

I think it has to do with the update, since everything worked well before, but two days later, the first time I recorded something, it went wrong. The new features in the update report show that things have changed for the camera.

I have looked for solutions to return the operating system before the update, but I can not find anything.

What I can do?
