Galaxy S10 owners on Verizon are getting a new software update that brings the April 2019 security patch to the device. Verizon is the second of the four major North American carriers to be releasing the April security update for Samsung's latest flagships, although it's a bit late at this point as we're a week into May, which means we could see AT&T and T-Mobile skipping the April update altogether.
The update comes with software version G973USQU1ASD7; it's out for the Galaxy S10 at the moment but should be reaching Galaxy S10e and Galaxy S10+ owners as well in the next few hours. Verizon hasn't yet updated its official Galaxy S10 support page so we're not aware of the changelog, but the update hopefully includes the new dedicated camera Night mode. If you have a Galaxy S10e, S10, or S10+ on Verizon, you can check if the update is available by tapping the Download and install option in the Settings » Software update menu on the phone.
We also have the firmware for the new update in our firmware database, and you can use that to upgrade if the over-the-air update isn't yet available for your device. Do let us know what changes you see once you've installed the update on your Galaxy S10.
