Bug description

When listening to a vocal message, putting the phone near your ear doesn't make anything at all, while I am expecting the proximity sensor to turn off the screen and send the sound to the earpiece instead of the loudspeaker.

Steps to reproduce

• listen to a vocal message
• darken the proximity sensor
• nothing happens

Actual result: nothing happens
Expected result: the sound should be sent to the earpiece while the screen should be turned off

Device info

Device: Honor Model 6X (BLN-L21)
Android version: 6.0
Signal version: 3.28.4

How about an additional button like in the webrtc call screen for manual switch between earpiece and speaker.
Here a mockup

It is implemented perfectly in Telegram! No ear touching the screen makes the speaker play the voice message, and the ear touching the phone makes the earpiece play it.

Right now it is horrible: When I receive a voice message in the library or in the metro, I cannot listen to it because it will in any case be played by the speaker and everybody can hear it.

Only exception: With earplugs it works well.

My phone is a Nexus 5x.

@moxie0 switching from speaker to earpiece works, but screen doesn’t turns off (i.e. the screen isn’t locked). I made so an unintended change (i.e. set new value for disappearing massages) with my ear :confused:
imo, screen should be locked if placed to ear

Any chance for a manual toggle in some menu?
This features works very inconsistently for me on my phone. I end up hitting buttons with my cheek half the time.

For instance in Wechat you can set all messages to play "privately" through the earpiece, so you don't need to be so careful about keeping you ear perfectly sandwiched to the light sensor
