In a surprising development, Samsung has released new software updates for the Galaxy S20 series in various markets with different changelogs and security patches on the same day. Over in its home country, Samsung released an update that brings call quality improvements to the Galaxy S20, S20+, and S20 Ultra and bundles the May security patch. In the US, the company is updating unlocked versions of the Galaxy S20 series devices with the June Android security patch.

Based on its firmware version and changelog, the update rolling out for the unlocked Galaxy S20 models in the US only brings a new security patch. It’s unclear if the camera improvements included in the update released for international models a couple of weeks back are present in the update for the unlocked US variants. The last time the carrier-free versions of the Galaxy S20, S20+, and S20 Ultra received an update with new features was way back in April, so it seems Samsung isn’t treating them the same as the carrier-locked models.

It remains to be seen when the international Galaxy S20 models will receive the June security update, but we will let you know once they do. In the meantime, if you own an unlocked Galaxy S20, S20+, or S20 Ultra, you can download the new update from the phone’s Settings » Software update menu or from our firmware archive. If you own a Galaxy S20 Ultra, you can check if the latest update includes camera improvements by seeing if there’s a new ‘close-up zoom’ feature in the camera that we have detailed here.
