A couple months ago, Samsung updated the Galaxy S10 to give it a dedicated Night Mode for those times you're capturing photos in low light. Fast-forward to today and that feature has finally begun arriving on U.S. versions of the S10.
AT&T is now pushing an update to its Galaxy S10 models, and the update includes a dedicated Night Mode for the camera app. User KenC on the SamCentral Discord server (via XDA-Developers) got the update on their AT&T Galaxy S10+, but it should be rolling out to Galaxy S10 and S10e models as well.
Night Mode is meant to help you capture better photos in low-light conditions. The Galaxy S10 actually launched with a low-light camera feature called Bright Night, but you couldn't enable it manually. The addition of a dedicated Night Mode lets you manually activate the low-light shooting mode for those times that you want to be sure that it's on.
The update for AT&T's Galaxy S10 models also includes the June 2019 security patches and a QR scanner that lets you scan QR codes using your phone's Camera app rather than having to launch Bixby Vision.
AT&T hasn't officially announced these updates yet, but if they've started hitting devices, your AT&T Galaxy S10, S10+, or S10e should get its over the air update in the coming days. Stay tuned for it and let us know when the update arrives!
