Did you own a Galaxy before? For how long? In my experience Samsung does this through updates over time. Your S23 is good for up to about 6 years or until around 2028-2029; you will have this stuff pushed to your phone by end of 2024.
The problem with all the phone reviewers is they put zero thought/effort into the patterns of brands in how they support past models past mentioning how long you get security patches for. Reviewers just do not talk about this on past models in relation to new models.
