An analysis of the latest Google Messaging update suggests it may be approaching having one-to-one encryption for RCS, according to 9 to 5 Google (via APKMirror). Rich Communication Services, or RCS, is the successor to text messaging and does what most other text services do, but without the final encryption that apps like Signal and iMessage have. Its widespread assumption has been a bit messy, but the major US mobile operators announced late last year that they would offer RCS in 2020.

An internal design of Google Messages v. 6.2 has several lines of code that provide clues about possible future features of the app, including 12 new strings that refer to encryption, according to 9 to 5 GoogleAnalysis. Not enough information is available to determine if the sender and recipient of texts in messages should use the app for final encryption to take effect. The code updates suggest a setting that will allow users to decide whether to allow other Android apps that have access to messages to see encrypted messages as well.
There is no way to know if or when Google will ever send the encryption feature from end to end. But the company has said before that it worked with it, so it seems likely to happen.
