Android app hangs on Team, Contacts, and Voicemail, MyPhone notification stream times out on multiple phones

[blackacoustic]

Hello,

I am seeing an issue with the 3CX Android app where Team, Contacts, and Voicemail load forever on two different Android phones / extensions.

What works normally:

• Calls
• Provisioning
• SIP tunnel
• Call history
• Web Client

What fails:

• Android app foreground use still hangs on Team, Contacts, and Voicemail
• The issue happens on both Wi-Fi and mobile data
• The issue happens on two separate Android phones

PBX environment:

• 3CX version: 20.0.9.995
• Repository channel: production candidate
• Deployment: on-premise / self-managed
• License: BASIC Edition, 4 SC

Android app environment:

• Android app: 20.7.0.5
• At least one affected phone is on Android 17 / API 37

What I already tried:

• Reprovisioned both extensions
• Removed and re-added the account on the phones
• Updated the Android app from Play Store and retested
• Disabled battery optimization
• Enabled background data
• Restarted 3CX services, including Management Console, System Server, and Call Flow services
• Tested on both Wi-Fi and mobile data

Verbose log details:

• Authentication succeeds
• MyPhone session creation succeeds
• Then the app repeatedly logs onNotificationStreamFailure (SocketTimeoutException) - timeout
• After that it logs stream fail, relogin

Because the issue happens in foreground use, on multiple devices, and on both Wi-Fi and mobile data, it does not look like a background push or battery optimization problem. It also does not seem related to SIP registration, call history, or the Web Client.

If anyone has seen this before, I would appreciate guidance on whether this is a known Android app / MyPhone stream issue for 20.7.0.5 with PBX 20.0.9.995, and whether there is a supported production fix or update.

Thank you.
