/e/ os does’t switch speaker when held to ear

• /e/ version: 0.19-20211027142972
• Device model(s): fairphone 3
• Device rooted: yes

Summary

When listening to voice-messages from signal, I used to be able to hold the phone to my ear as if making a phone call. My old phone used to automatically switch voice-output from external speaker to ear-speaker. That way I was able to enjoy some privacy while listenig to messages in public transport directly on my ear. I’ve noticed that with my fairphone 3 & /e/ this switch does’t seem to happen. Voice messages on signal are played through external loud speaker only.

The problem

Steps to reproduce Play sound, e.g. voice message Pick up phone, hold it to your ear

What is the current behavior? Sound continues playing through loudspeakers

What is the expected correct behavior? loudspeakers should shut up sound/voice message should be played through ear-speaker
