This year, Microsoft will be making two (2) major changes to Teams Native phones:

So where does the chicken and the egg fit into this? Native Teams Phones must be running Android 12 to be managed in Intune with AOSP. Teams administrators need to get ready to update their phones to Android 12 before the switchover to AOSP in Intune. Later this year we will publish a follow-up article on configuring Intune and AOSP to support these updated phones, and as events warrant, we will publish updates as we get them from the Native Teams Phones manufacturers.

There are some significant changes happening this year for Native Teams Phones—updating them to run under the Android 12 operating system and replacing the Android Management platform in Microsoft Intune. The availability of the updates and guidance from the manufacturers varies.
