It's been more than three years since the Galaxy S7 and S7 edge were launched, and despite what our headline may make you believe, it's obvious that the S7 and S7 edge will continue to receive updates from time to time. The bad news is that they've just been switched to that time frame from the one they were previously in where it got updates every three months. Now it looks like they will get irregular updates instead.
It turns out that Samsung has three categories of devices which they decide how often receives security updates. High-end new devices get them monthly, next is the quarterly updates, and finally we have what Samsung calls "other regular security updates". This is where the S7 and S7 edge have ended up, which is certainly understandable given their age.
To be fair, Samsung's updates are a bit of an irregularity. Considering the default scenario for Android smartphones - even Google only promises three years of updates for its Pixel line of handsets.
Oddly enough though, the Galaxy S7 active, which made its debut just three months after the S7 and S7 edge in 2016, is still supposedly getting security patches every month. It's the only device from 2016 to still be on that particular list for some strange undisclosed reason.
