    Thanks Paul, this sounds like a bug for this particular device (Galaxy A03s). I have raised the Bug here:

     

    Bug: Incoming calls not ringing on Galaxy A03s · Community (microsoft.com)

     

    If you could 

    1.) Raise a support ticket via the Microsoft 365 admin centre

    2.) In this thread put down the build numbers of the Teams App and the Galaxy AO3s

     

    I will raise this to Microsoft engineering to review tonight. Of course, it could take a while to resolve but at least we are pushing it in the right direction. Thanks for providing all the information.

     

    Hope this has answered your question

     

    Best, Chris

We had the same problem with several phones (at least 2 different samsung model).We passed the battery parameter for Teams apps on unrestricted instead of optimized and it seems it resolve the problem.

MichaelOliv Did you pass this setting via Intune or directly on the phones? We have similar issues with Samsung Galaxy XCover Pro devices. Also the mic volume is verry low and somehow can't be changed in the mobile app.

    Directly on phone. I don't know if it's possible by Intune.

      We have received and applied these recommendations from Samsung using the Knox Service Plugin via Intune MDM platform.
      1. Battery Optimization Settings
      a. Go to Settings on your phone
      b. Tap Apps
      c. Search for and select “Your App” then tap Battery
      d. Disable Optimize battery usage for “Your App”

      2. Sleeping App Settings
      a. Go to Settings on your phone
      b. Tap Battery & Device Care, then tap Battery
      c. Tap Background usage limits
      d. Disable Put unused apps to sleep
      e. Tap Sleeping Apps: make sure “Your App” is not there
      f. Tap Deep sleeping apps: Tap More options (three vertical dots) and tap Remove apps

      3. Battery Saving Mode Settings
      a. Go to Settings on your device
      b. Tap on Battery and Device care, then Battery
      c. Disable Power saving mode

      4. Optimize battery usage
      d. Go to Settings on your device > Apps
      e. Tap on the three dots menu (⁝), then Special Access
      f. Open Optimize battery usage
      g. Expand the list to All apps from the drop-down filter
      h. Make sure that the toggle for “Your App” app is switched OFF
      i. Open Optimize battery usage
      j. Expand the list to All apps from the drop-down filter
      k. Make sure that the toggle for “Your App” app is switched OFF

      5. Auto-optimize daily
      a. Go to Settings on your device
      b. Tap on Battery and Device care
      c. Tap on the three dots menu (⁝), then Automation
      d. Make sure that Auto optimize daily is disabled

      Hope this works out for any of you with the same problems !

        We have the same issue on the Samsung A50/A52/A53. If phone has been idle for some time (for example early in the morning), incoming Teams calls are not received. A 'missed call' notification does arrive after the caller hangs up. If you know someone is calling you (but call is not received on phone) and you turn on the phone screen, the call suddenly is received. So it must have something to do with idle/sleep-mode.

         

        Tried logging out and back in
        Tried reinstalling Teams app (and even factory resetting phone)
        Happens on multiple phones, multiple users
        Happens on Wifi and 4g
        Phone firmware and Google Play Services are up-to-date
        Teams is up-to-date
        No silent mode, notifications are allowed

        Teams is excluded from being optimised (for background-data, battery and memory cleaning)
        Battery saver is disabled
        Sleeping apps is disabled
        Auto-optimize: was able to disable auto-reboot-option for auto-optimize, but completely disabling this feature seems no longer available in Android 13? Maybe this is the culprit?

         

        Anyone else still experiencing this? Any other solutions available?

         

        PS: Microsoft ticket has been raised.

         

        Software info:

        Teams 1416/1.0.0.2023012702
        Galaxy A53 5G Model Number: SM-A536B/DS

        Android 13, security patch january 2023
