So now, what Samsung is doing is taking that a step additional by saying it’s going to present the Android safety patches for an further 12 months past that three-year interval — which, once more, is implausible. Whereas full-fledged working system upgrades completely do play a big position in areas like efficiency, privateness, and safety, the smaller safety patches alone are nonetheless a lot better than nothing (clearly, proper?!). And understanding you will obtain these for 4 years as an alternative of three — or typically even much less — is a precious little bit of assurance for anybody who hangs onto a cellphone even as soon as it is reached, erm, aged golden-ager standing.
