Google’s messaging app, Messages, will stop working at the end of March on Android mobile phones that are not certified Google Mobile Services (GMS), a measure that could affect some Huawei devices.
Google Messages is usually installed by default in many of the mobile phones with Android operating system and if it is not, it is easy to download and useas it does not require a Google account.
However, a line of code in version 7.2.203 of the ‘app’ indicates that not all mobiles can use it. Specifically, and as reported in XDA Developers, the code specifies that “on March 31, Messages will stop working on uncertified devices.”
Uncertified Android devices are those that use a basic layer of Android but do not have GMS, as is the case, for example, with some Huawei models.
In the aforementioned portal they indicate that this change could be due to rollout of end-to-end encryption in Rich Communication Services (RCS) as they could not guarantee the security of uncertified telephone communications.
