I believe someone else in this thread has mentioned this already, For most people the feature set on phones has been stagnant for many years. Most users have their use case met already and additional features are really just bloat (for the most part). Not all people are into tech, and a phone is simply a tool. And therefore don’t always want/need the latest and greatest.
Remember when Google’s motto was “Don’t be evil”? Pepperidge Farm remembers.
