Samsung rolled out a big Galaxy S10 update last month which brought a dedicated Night mode for the camera. What the update basically did is allow manual access to the Night mode which would previously only trigger automatically. The results remained more or less the same, but at least you could now choose when you wanted the Night mode to work its magic.
The feature has since trickled down to devices like the Galaxy S9 and the Galaxy Note 9 with the June 2019 update. Unfortunately, the Galaxy S10 didn't get the feature in last month's update, and it's not getting the dedicated Night mode with this month's update either.
US Galaxy S10 isn't getting a couple of new features
T-Mobile today started rolling out the June 2019 security update for the Galaxy S10 on its network. While the update firmware version G973USQS2ASF7 does bring the latest security patch for the month of June 2019, it doesn't bring the dedicated Night mode. This is hardly surprising. The June update that T-Mobile released for the Galaxy Note 9 three days ago didn't come with these features either.
The June update for the Galaxy S9 and Galaxy Note 9 even added the ability to scan QR codes from the camera app itself without having to use Bixby Vision. This feature wasn't present on the Galaxy S10 series initially but the June update for the Exynos variant added it. Since US customers get the Snapdragon variant, they won't be happy to hear that this update doesn't include the built-in QR scanner as well.
Other models of the Galaxy S10 will soon receive this update as well. T-Mobile's rival carriers will also be rolling out the update for the Galaxy S10 series on their networks in the near future. It's going to be the same situation for everyone and users will certainly not be happy about it.
This means that it may not be until when the July update starts rolling out that the Snapdragon-variant gets these features. Even that can't be said for sure, but many will keep their fingers crossed for it nonetheless.
