Our latest OS release adds a sandboxed Google Play toggle for extending RCS compatibility in Google Messages to the rest of the carriers supporting it by granting ICC authentication access to sandboxed Play services. T-Mobile is the main one requiring it.

There are also the usual updates to the Linux kernel and the latest Android security preview patches. March 2026 AOSP patches have been finalized for a while other than patches being deferred. Most of the ones being added now are for the next major quarterly batch in June 2026.

We also added a new implementation of call recording which should be more robust including better handling of network handovers. It's an opt-in toggle in the Dialer app until it gets a lot of testing and then it can replace the existing implementation we made a long time ago.
