Many phones are essentially abandoned by the manufacturer and don't receive any security updates not too long after release, which might just be an issue: https://source.android.com/docs/security/bulletin/2023-12-01

Not only that, but many apps won't run on the older versions of the OS either, due to the API level deprecation in Android: https://support.google.com/googleplay/android-developer/answ...

In other words, you don't really get much of a choice, unless you are buying a flagship device and not everyone will be able to do that. The same goes for the comparatively expensive iPhone devices, the cost also being a factor there for many.
