This is an issue not only for phones, but any device that has an update(able) operating system. This includes PCs through to TVs and now even more and more appliances as they become smart. There has been a post on this forum about smart tvs becoming less smart the older they get.
It appears that manufacturers have different life expectations than their customers, and possily view the ‘updates’ as a way to sell new models as the older models lose functionality.
Maybe it is time for a product life guide to be prepared like that suggested here. Software/OS support/functionality would be part of the product life expectation.
