Hello @GManUK
welcome to the Poly Community.
Same issue as already discussed here:
- https://community.poly.com/t5/Video-Endpoints/Poly-X-Devices-Go-Offline-in-TAC-Unable-to-force-reboo...
- https://community.poly.com/t5/Video-Endpoints/Studio-and-G7500-Devices-Freeze-when-Idle-in-Teams-Mod...
- https://community.poly.com/t5/Video-Endpoints/Poly-X50-Studio-going-offline/td-p/118676
Scheduling a periodic reboot seems to stabilize the systems (nightly reboot just like the Microsoft MTR does).
No fix for this as this is the Microsoft Teams application crashing taking down the whole Android System via an ANR.
An ANR will occur if you’re running a process on the UI thread which takes an extended time, usually around 5 seconds. In this case, our Partner Microsoft’s app seemed to have an issue.
On mobile phones, the user usually would be presented with a warning, but the way Android is running on our devices this seems to be suppressed.
Initially, we got a confirmation from the Microsoft Product Group that a fix included in Teams app U3CY22 will prevent the ANRs and therefore avoid the trigger for the crashes in the system service.
Based on our current findings the latest failures indicate that Teams ANRs with U3CY22 1449/1.0.96.2022120503 still occur, but Studio X failures are for an error in the kernel running on our 3.14 .x based on the Android 8.1 release.
A case reference for their Support Team to match this would be

From my knowledge, our partner Microsoft will not fix this for Android 8.1 and therefore expects users to upgrade to PolyOS 4.0 once we release this.
The delay in the release is caused by work on resiliency alternatives as PolyOS 4.0 will move the system to Android 10.
Best regards
