and literally any 10 year old android phone can run not just the latest security patches but even the latest android. you are taking the iphone limitation of 'os must be from hardware manufacturer' and for some reason applying it to android phones.
my 10 year old motorola nexus is running android 10 -which is the current version. you install the new os on android by downloading an app, which installs the new os on reboot. it takes 15 minutes, and gramma can do it.
next you'll tell me mac laptops are better because you can't put windows 10 on your old hp laptop, because hp's system image for it only goes to windows 7.
