Samsung is pushing out yet another update with camera improvements for the Galaxy S20 series. Available for both the Exynos and Snapdragon models (only in Korea for the Snapdragon model at this time), the latest Galaxy S20 update comes with firmware version G98xxXXU2ATE6. This is the second update Samsung has released that includes the May 2020 security patch, though it is only rolling out in markets where the initial May security update wasn't made available, at least right now.
Samsung isn't telling us what kind of improvements we can expect from the camera on the Galaxy S20, S20+, and S20 Ultra after the latest update, but some users on Reddit suggest that Night mode now offers better image quality. Whether or not autofocus performance on the Galaxy S20 Ultra has received another boost is unclear at this time, though we're assuming Samsung has already done all it can on that front, especially since some of the autofocus limitations are based in hardware.
If the new Galaxy S20 update is available in your country, you will eventually get a notification allowing you to download it over-the-air. You can also try and download it right away by tapping Download and install in your phone's Settings » Software update menu. If that doesn't work, you can always download the latest firmware from our archive and use it to update your phone manually using a Windows PC.
