After Verizon and T Mobile, AT&T is the third major operator in the United States to launch another Samsung Galaxy S9/S9+ update. Like the other two network operators, AT & T provides customers who have purchased Samsung’s flagship products the July security patch. In addition to this, AT & T has announced that it is bringing Messaging as a Platform (MaaP) to Samsung Galaxy S9 and the owners of S9 +. This specific service combines advanced messaging features with standardized interfaces for chatbots and plugins.
Finally, the carrier mentions that the update adds network performance improvements, but no additional details are provided. If you want to update your phone, you should look for these specific software updates: R16NW.G960USQU3ARG7 (S9) and R16NW.G965USQU3ARG7 (S9 +).
Do not forget that even if the changes are not too many, this update remains quite important because AT&T confirms that it weighs 546 MB. So make sure you have enough storage space.
