Samsung Galaxy S20 vs Galaxy S24: Should you upgrade?

Galaxy S24 1
Damien Wilde / Android Authority

The Galaxy S20 was a very capable device when it first launched, but as of 2024, it’s no longer receiving active updates. It was just beyond the cutoff date when Samsung announced it would offer four years of Android updates and five years of security updates, meaning it received its last Android update in 2022 with Android 13.

Samsung has upped its game even further with the Galaxy S24 lineup, promising a full seven years of Android version and security updates. This will take support into 2031. If you’re reading this and still hanging on to your Galaxy S20, odds are you don’t like upgrading your phone often, which is a huge selling point of the Galaxy S24 lineup.

The fact that the Galaxy S20 is no longer receiving updates means it's time to upgrade.

There are plenty of other benefits to upgrading, of course. Everything from camera hardware to build materials has been substantially upgraded, resulting in a much better overall device. Following Google’s lead with the Pixel 8 devices, Samsung has also added many new AI features to the series, most of which won’t be available on any older flagship phones from the company, let alone phones from 2020.

The Galaxy S24 is one of the best small phones you can buy, but the larger Galaxy S24 Plus has faster charging speeds, a larger battery, and more RAM. In terms of future-proofing, it’s the one we recommend picking up if you don’t mind the extra size. However, the SD card slot found on the Galaxy S20 series is no longer found on the S24 series, so make sure you get the right size because you can’t expand it later.

Do you think it's worth upgrading from the Galaxy S20 to the Galaxy S24?
