Bug description

When making a Signal audio call, the microphone stops working both when viewing other apps (i.e. when Signal is running in the background) and when the screen is off. This only affects microphone (sending audio), and speakers (receiving audio) continue to function as expected. Bringing Signal back into the foreground, with the screen on restores microphone functionality. Additionally, enabling Picture-in-Picture mode with the call screen hovering over other apps allows the microphone to work normally.

Essentially, in order for a Signal call to work as expected, Signal must always be in the foreground and the screen must always be on, or Picture-in-Picture mode must be enabled. Tabbing into other apps without Picture-in-Picture or turning off the screen disrupts this.

Steps to reproduce

Make a Signal audio call
Switch to other app / Turn off the screen during the call (without Picture-in-Picture)

Actual result: Microphone stops sending audio Expected result: Microphone should continue to function with others apps in foreground, or with screen off.

Device info

Device: Motorola Moto G Pure (XT2163DL) Android version: 12 (Build No. S3RHS32.20-42-13-3-12-4) Signal version: 7.14.1

Updated Signal on the device to 7.14.2, the same issue still persists.

I'm affected by this as well. It is a serious problem, as it basically means I can no longer use signal to talk to people while I walk around.

I use a Moto G Power 2022, with Android 12. My Android build is S3RQS32.20-42-10-12-5-7, and my Signal version is 7.14.1.

I am an end-user, so I'm reporting an issue with the physical device I'm using, as are the other users reporting in this issue.

I have no experience with Android emulators so I have no idea how to test anything with them. All I can do is recognize patterns: Every report so far is Android 12 or higher and using Motorola or Samsung hardware, probably on vendor version Android builds.

I'm having the same issue;

Phone info: Make: OnePlus 8 Pro Model: IN2023 Android version: 13

Signal info: Currently running on version 7.15.4, but I did an update to it to see if it solved my issue and it didn't. I don't know what version I was on before

I have localized it to be Signal, as I've tried other apps and they keep microphone "on" while screen is locked. I've only tried it with locked screen

Hello everyone,

A fix for this issue should be rolling out now, and should reach everyone within the day.
