I’d love if they added a minimum security-update time for the OS. 5 years of OS upgrades should be the norm, and at least 7 more years of life-support, where security updates are provided.
It is ridiculous how fast phones become unsupported and unsafe. The systems are so specialised that open source OS can not support them all. It’s all proprietary technology, dependant on proprietary code.
Once the last security update is shipped, the phone very quickly becomes a serious security vulnerability. Modern messaging formats such as emails and whatsapp become potential vectors of an attack. Visiting a Website might be enough to compromise ones phone. Even if every application you depend on didn’t already drop support, the phone is basically e-waste because of the OS.
On this front, Apple has actually been decent. They support their old hardware much longer than many android brands. However I still think anything below 10 years is absolutely ridiculous as it renders the whole device unusable.
I wonder if in future we will have the same issue with cars and other items now dependant on internal computers.
