Bad audio on Samsung only on Video active

Hi all,
I’m trying your latest Jitsi Meet app and I’m experimenting a bad audio only from Samsung A5 (2017) devices when the video mode is active (speakerphone on).
All other connected devices hear a very distorted sound, as if the microphone of this device had a too high gain. When you switch to “audio only” mode, all other devices hear normally.
No difference on iPhone, other Android devices or Web client if the source is this Samsung model.
