To take advantage of the top of the line photography hardware of the Galaxy S10, Samsung baked what it calls Instagram Mode into the stock camera app.
What this mode does is to allow users to capture and upload images and videos to their Instagram stories directly from the S10 camera app, that is, without the need of leaving the camera app. This mode tags along things like Instagram editing tools, stickers, filters, and what not, ensuring that you get that complete Instagram feel right from within the S10 camera app.
Now, in the latest update rolling out to the AT&T Galaxy S10, the carrier is enabling this Instagram Mode as well as improving the performance of the camera in general as well as optimizing the fingerprint function.
The update making these changes to the S10 has software version G973USQU1ASBA, the same version that was recently pushed to Sprint, Verizon and T-Mobile variants.
Given that the other three carriers also provided a similar update to the Galaxy S10+ and S10e, we are positive that the duo is also on the receiving end of build ASBA, meaning February 2019 security patches are part of it.
