[Solved] Microphone mute/unmute in calls not working since Android-app version 2.27

Troubleshooting Mobile Apps

Dear Foum,

since the new Mobile App Version: 2.27.0 (Build 6000627) from android, muting or unmuting of microphone in calls is not working anymore. First time of occurence with Mattermost-Server version 9.8.11. An upgrade to versoin 10.5.2 and then 10.7.1 didnt changed behaviour. Calling from desktop-app is working (direct-calls)!

The log on the android device says something like

2025/04/26 16:29:55.855 INFO  TurboLogger: rn-webrtc:pc:DEBUG 0 getStats +2s
2025/04/26 16:29:57.438 WARN  TurboLogger: Handling Javascript error calls: from RTCPeer, error on mute: false
2025/04/26 16:29:57.439 ERROR TurboLogger: calls: from RTCPeer, error on mute: {
  "jsEngine": "hermes"
}

Until version 2.69 no problems happend. Notifactions and Permissions on the phones are allowed. Is this a bug related to JavaScripts handling with Hermes?

Thanks in advance for any help.

Hi Philipp, welcome to the Mattermost community! :waving_hand: Thanks for sharing the detailed logs - it does sound like this could be related to the Hermes JavaScript engine introduced in the newer app versions; I recommend reporting this directly via our Mobile Apps GitHub repository so our team can investigate further.

Hi John, Thank you for the welcomining :slight_smile:

In the meantime, they was a Call-Plugin Update for the server available, from version 1.6.0 to 1.7.1. (iam on Server version 10.7.1). This somehow solved the problem. I assume that some communiction request from the mobile-client to the server was not working properly. here the excerprt from the server-log of the update
