Update 1 (03/23/2020 @ 9:59 AM ET): The US Snapdragon variant of the Galaxy S20 is now getting the new update. Scroll to the bottom for more information. The article as published on December 22, 2019, is preserved as below.

The megapixel race is back, and the top-end 'Ultra' variant of the Samsung Galaxy S20 is one of the prominent contenders, boasting a massive 108MP ISOCELL HM1 sensor. The company already rolled out the first software update for the phone to improve the focusing issues, but owners are still reporting autofocus glitches. Samsung is now rolling out a new software build with an updated camera firmware to tackle the situation.

Tagged with the version number G98xxXXU1ATCH, this update is intended for the Exynos-powered international variant of the Galaxy S20 lineup. At the time of writing this article, the OTA should hit the units in various Asian and European countries, including India. The base models, i.e. the Galaxy S20/S20+ also utilize the same camera stack as the Ultra variant (despite having different hardware sensors), thus the owners of these phones should also benefit after installing the new update. The 5G-capable variants are picking up similar updates as well in different regions.

While the changelog does mention about camera performance improvements, the underlying changes are quite huge. Samsung is shipping a new version (10.0.01.98 to be precise) of the stock camera app, accompanied by an improved camera firmware. The initial feedback is mixed though, so do let us know your experience after installing the OTA. Sideloading the updated camera app on Snapdragon models might not be fruitful, as it depends on the new firmware as well.

Interestingly, all three Galaxy S20 models in India received an intermediate update before. Bearing version number G98xFXXU1ATC1, this build apparently brought stability improvements. Now that Samsung is aware of these pesky bugs (e.g. the random reboot issue), there is no doubt that they will push a bunch of similar updates in the near future.

After the international units, both the carrier unlocked (U1) and carrier models (U) of Galaxy S20/S20+/S20 Ultra are getting the ATCH firmware with the camera improvements.
