The biggest problem of the Galaxy S10 is addressed in a day-one update on US carriers32
T-Mobile, Verizon, and Sprint have all confirmed imminent rollouts for their respective variants of the S10, S10 Plus, and S10e, but we're guessing the same enhancements will be delivered to AT&T-specific and US unlocked models over-the-air soon enough. Interestingly, while T-Mobile and Sprint are listing March 8 as the OTA release date of these minor OS revisions, Verizon's support documents suggest the updates have been around since Tuesday, March 5, technically making them "day zero" or even "day -3" affairs.
The all-round vague changelogs also differ from carrier to carrier, as Sprint mentions "bug fixes and performance enhancements", Verizon claims to provide "camera enhancements and the most up to date Android security patches" on your brand-new devices, while T-Mobile lists "camera and fingerprint feature enhancements" and "security patches" as the focus of these updates.
It's safe to assume all wireless service providers are actually sending the same software enhancement packages to the Galaxy S10, S10+, and S10e, including February (not March) security patches and fingerprint recognition improvements. Intriguingly, even the Galaxy S10e is getting a little something to make its side-mounted biometric sensor better. As for the Galaxy S10+, while we didn't find the ultrasonic in-display fingerprint scanner to be completely useless in our in-depth review, it certainly looked like it needed work in terms of both speed and reliability.
Hopefully, this update will be enough to address our concerns, and if not, that others will follow before long. Finally, even though we didn't notice anything wrong with the cameras on the Galaxy S10+, there's always room for refinement in that department, and it's nice to see Samsung is wasting no time trying to achieve photographic perfection.
