There’s a new Google Messages update page that takes up your phone’s entire display every time you open the app.
Granted, keeping your apps up to date is important, and this new system will help get that across to users. But we’re not sure annoying the hell out of the user about it is the best strategy.
Unfortunately AOSP (controlled by Google, keep that in mind) doesn’t provide an API for RCS messaging. That means, you can’t use a third-party app. Google doesn’t allow you to use a third party app because they want to force you to use their proprietary garbage.
